VISION_TEXT_DUAL_ENCODER_START_DOCSTRING = r"""
This class can be used to initialize a vision-text dual encoder model with any pretrained vision autoencoding model
as the vision encoder and any pretrained text model as the text encoder. The vision and text encoders are loaded
via the [`~TFAutoModel.from_pretrained`] method. The projection layers are automatically added to the model and
should be fine-tuned on a downstream task, like contrastive image-text modeling.
In [LiT: Zero-Shot Transfer with Locked-image Text Tuning](https://arxiv.org/abs/2111.07991) it is shown how
leveraging pre-trained (locked/frozen) image and text model for contrastive learning yields significant improvment
on new zero-shot vision tasks such as image classification or retrieval.
After such a Vision-Text-Dual-Encoder model has been trained/fine-tuned, it can be saved/loaded just like any other
models (see the examples for more information).
This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
etc.)
This model is also a Keras [Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it as a
regular Keras Model and refer to the TF documentation for all matter related to general usage and behavior.
Parameters:
config ([`VisionEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
Initializing with a config file does not load the weights associated with the model, only the
configuration. Check out the [`~TFPreTrainedModel.from_pretrained`] method to load the model weights.

- A path or url to a *PyTorch checkpoint folder* (e.g, `./pt_model`). In this case, `from_pt`

- A path or url to a *PyTorch checkpoint folder* (e.g, `./pt_model`). In this case, `from_pt`

model_args (remaining positional arguments, *optional*):
All remaning positional arguments will be passed to the underlying model's `__init__` method.
kwargs (remaining dictionary of keyword arguments, *optional*):
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,

- To update the text configuration, use the prefix *text_* for each configuration parameter.

Main method to featurize and prepare for the model one or several sequence(s).
Args:
raw_speech (`np.ndarray`, `List[float]`, `List[np.ndarray]`, `List[List[float]]`):
The sequence or batch of sequences to be padded. Each sequence can be a numpy array, a list of float
values, a list of numpy arrays or a list of list of float values. Must be mono channel audio, not
stereo, i.e. single float per timestep.
padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`):
Select a strategy to pad the returned sequences (according to the model's padding side and padding
index) among:
- `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
sequence if provided).
- `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
acceptable input length for the model if that argument is not provided.
- `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
lengths).
max_length (`int`, *optional*):
Maximum length of the returned list and optionally padding length (see above).
truncation (`bool`):
Activates truncation to cut input sequences longer than *max_length* to *max_length*.
pad_to_multiple_of (`int`, *optional*):
If set will pad the sequence to a multiple of the provided value.
This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability
`>= 7.5` (Volta), or on TPUs which benefit from having sequence lengths be a multiple of 128.
return_attention_mask (`bool`, *optional*):
Whether to return the attention mask. If left to the default, will return the attention mask according
to the specific feature_extractor's default.

- `'pt'`: Return PyTorch `torch.Tensor` objects.
- `'np'`: Return Numpy `np.ndarray` objects.

Model configuration class with all the parameters of the model. Initializing with a config file does not
load the weights associated with the model, only the configuration. Check out the

"""
WHISPER_INPUTS_DOCSTRING = r"""
Args:
input_features (`torch.FloatTensor` of shape `(batch_size, feature_size, sequence_length)`):
Float values mel features extracted from the raw speech waveform. Raw speech waveform can be obtained by
loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via
the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the
[`AutoFeatureExtractor`] should be used for extracting the mel features, padding and conversion into a
tensor of type `torch.FloatTensor`. See [`~WhisperFeatureExtractor.__call__`]
attention_mask (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
Mask to avoid performing *SpecAugment* data augmentation on padding token indices. Mask values selected in
`[0, 1]`:
- 1 for tokens that are **not masked**,
- 0 for tokens that are **masked**.
[What are attention masks?](../glossary#attention-mask)
decoder_input_ids (`torch.LongTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
Indices of decoder input sequence tokens in the vocabulary.
Indices can be obtained using [`WhisperTokenizer`]. See [`PreTrainedTokenizer.encode`] and
[`PreTrainedTokenizer.__call__`] for details.
[What are decoder input IDs?](../glossary#decoder-input-ids)
Whisper uses the `decoder_start_token_id` as the starting token for `decoder_input_ids` generation. If
`past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
`past_key_values`).
decoder_attention_mask (`torch.LongTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
be used by default.
If you want to change padding behavior, you should read
[`modeling_whisper._prepare_decoder_attention_mask`] and modify to your needs. See diagram 1 in [the BART
paper](https://arxiv.org/abs/1910.13461) for more information on the default strategy.
head_mask (`torch.Tensor` of shape `(encoder_layers, encoder_attention_heads)`, *optional*):
Mask to nullify selected heads of the attention modules in the encoder. Mask values selected in `[0, 1]`:
- 1 indicates the head is **not masked**,
- 0 indicates the head is **masked**.
decoder_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
Mask to nullify selected heads of the attention modules in the decoder. Mask values selected in `[0, 1]`:
- 1 indicates the head is **not masked**,
- 0 indicates the head is **masked**.
cross_attn_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:
- 1 indicates the head is **not masked**,
- 0 indicates the head is **masked**.
encoder_outputs (`tuple(tuple(torch.FloatTensor)`, *optional*):
Tuple consists of (`last_hidden_state`, *optional*: `hidden_states`, *optional*: `attentions`)
`last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)`, *optional*) is a sequence of
hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the decoder.
past_key_values (`EncoderDecoderCache` or `tuple(tuple(torch.FloatTensor))`, *optional*):
Pre-computed hidden-states that can be used to speed up auto-regressive (sequential) decoding. There are
four sets of pre-computed hidden-states: key and values states in the self-attention blocks (2) and
in the cross-attention blocks (2). The `past_key_values` are returned when `use_cache=True` is passed or
when `config.use_cache=True`
Two formats are allowed:
- An [`~cache_utils.EncoderDecoderCache`] instance;
- Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
`(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
`(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
`decoder_input_ids` of shape `(batch_size, sequence_length)`.
decoder_inputs_embeds (`torch.FloatTensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be
input (see `past_key_values`). This is useful if you want more control over how to convert
`decoder_input_ids` indices into associated vectors than the model's internal embedding lookup matrix.
use_cache (`bool`, *optional*):
If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
`past_key_values`).
output_attentions (`bool`, *optional*):
Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
tensors for more detail.
output_hidden_states (`bool`, *optional*):
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
more detail.
return_dict (`bool`, *optional*):
Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
Indices depicting the position of the input sequence tokens in the sequence. It is used to update the cache
in the correct position and to infer the complete sequence length.

Args:
input_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`):
Indices of input sequence tokens in the vocabulary. Padding will be ignored by default should you
provide it. Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
[`PreTrainedTokenizer.__call__`] for details. [What are input IDs?](../glossary#input-ids)
attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
- 1 for tokens that are **not masked**,
- 0 for tokens that are **masked**.
[What are attention masks?](../glossary#attention-mask)
encoder_outputs (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
Sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention
if the model is configured as a decoder.
head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
Mask to nullify selected heads of the attention modules. Mask values selected in `[0, 1]`:
- 1 indicates the head is **not masked**,
- 0 indicates the head is **masked**.
cross_attn_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:
- 1 indicates the head is **not masked**,
- 0 indicates the head is **masked**.
past_key_values (`tuple(tuple(torch.FloatTensor))`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`):
Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of
shape `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`. The two additional
tensors are only required when the model is used as a decoder in a Sequence to Sequence model. Contains
pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
blocks) that can be used (see `past_key_values` input) to speed up sequential decoding. If
`past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
`decoder_input_ids` of shape `(batch_size, sequence_length)`.
inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation.
This is useful if you want more control over how to convert `input_ids` indices into associated vectors
than the model's internal embedding lookup matrix.
labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
Labels for computing the masked language modeling loss. Indices should either be in `[0, ...,
config.vocab_size]` or -100 (see `input_ids` docstring). Tokens with indices set to `-100` are ignored
(masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`.
use_cache (`bool`, *optional*):
If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding
(see `past_key_values`).
- 1 for tokens that are **not masked**,
- 0 for tokens that are **masked**.
output_attentions (`bool`, *optional*):
Whether or not to return the attentions tensors of all attention layers. See `attentions` under
returned tensors for more detail.
output_hidden_states (`bool`, *optional*):
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors
for more detail.
return_dict (`bool`, *optional*):
Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
Indices depicting the position of the input sequence tokens in the sequence. It is used to update the cache
in the correct position and to infer the complete sequence length.

"""A helper method to check if the passed module's key name matches any of the target modules in the optim_target_modules.
Args:
optim_target_modules (`Union[str, List[str]]`):
A list of strings to try to match. Can be also a full string.
key (`str`):
A key to search any matches in optim_target_modules

Returns:
`bool` : True of match object if key matches any target modules from config, False or
None if no match found
`bool` : If the matched target module is a regex to silence out the warnings in Trainer
for extra modules being found (only if `target_module_found=True` for an array of regex).

" Marseille, France (CNN)The French prosecutor leading an investigation into the crash of Germanwings"
" Flight 9525 insisted Wednesday that he was not aware of any video footage from on board the plane."
' Marseille prosecutor Brice Robin told CNN that "so far no videos were used in the crash investigation."'
' He added, "A person who has such a video needs to immediately give it to the investigators." Robin\'s'
" comments follow claims by two magazines, German daily Bild and French Paris Match, of a cell phone video"
" showing the harrowing final seconds from on board Germanwings Flight 9525 as it crashed into the French"
" Alps. All 150 on board were killed. Paris Match and Bild reported that the video was recovered from a"
" phone at the wreckage site. The two publications described the supposed video, but did not post it on"
" their websites. The publications said that they watched the video, which was found by a source close to"
" the investigation. \"One can hear cries of 'My God' in several languages,\" Paris Match reported."
' "Metallic banging can also be heard more than three times, perhaps of the pilot trying to open the'
" cockpit door with a heavy object. Towards the end, after a heavy shake, stronger than the others, the"
' screaming intensifies. Then nothing." "It is a very disturbing scene," said Julian Reichelt,'
" editor-in-chief of Bild online. An official with France's accident investigation agency, the BEA, said"
" the agency is not aware of any such video. Lt. Col. Jean-Marc Menichini, a French Gendarmerie spokesman"
" in charge of communications on rescue efforts around the Germanwings crash site, told CNN that the"
' reports were "completely wrong" and "unwarranted." Cell phones have been collected at the site, he said,'
' but that they "hadn\'t been exploited yet." Menichini said he believed the cell phones would need to be'
" sent to the Criminal Research Institute in Rosny sous-Bois, near Paris, in order to be analyzed by"
" specialized technicians working hand-in-hand with investigators. But none of the cell phones found so"
" far have been sent to the institute, Menichini said. Asked whether staff involved in the search could"
' have leaked a memory card to the media, Menichini answered with a categorical "no." Reichelt told "Erin'
' Burnett: Outfront" that he had watched the video and stood by the report, saying Bild and Paris Match'
' are "very confident" that the clip is real. He noted that investigators only revealed they\'d recovered'
' cell phones from the crash site after Bild and Paris Match published their reports. "That is something'
" we did not know before. ... Overall we can say many things of the investigation weren't revealed by the"
' investigation at the beginning," he said. What was mental state of Germanwings co-pilot? German airline'
" Lufthansa confirmed Tuesday that co-pilot Andreas Lubitz had battled depression years before he took the"
" controls of Germanwings Flight 9525, which he's accused of deliberately crashing last week in the"
' French Alps. Lubitz told his Lufthansa flight training school in 2009 that he had a "previous episode of'
' severe depression," the airline said Tuesday. Email correspondence between Lubitz and the school'
" discovered in an internal investigation, Lufthansa said, included medical documents he submitted in"
" connection with resuming his flight training. The announcement indicates that Lufthansa, the parent"
" company of Germanwings, knew of Lubitz's battle with depression, allowed him to continue training and"
" ultimately put him in the cockpit. Lufthansa, whose CEO Carsten Spohr previously said Lubitz was 100%"
' fit to fly, described its statement Tuesday as a "swift and seamless clarification" and said it was'
" sharing the information and documents -- including training and medical records -- with public"
" prosecutors. Spohr traveled to the crash site Wednesday, where recovery teams have been working for the"
" past week to recover human remains and plane debris scattered across a steep mountainside. He saw the"
" crisis center set up in Seyne-les-Alpes, laid a wreath in the village of Le Vernet, closer to the crash"
" site, where grieving families have left flowers at a simple stone memorial. Menichini told CNN late"
" Tuesday that no visible human remains were left at the site but recovery teams would keep searching."
" French President Francois Hollande, speaking Tuesday, said that it should be possible to identify all"
" the victims using DNA analysis by the end of the week, sooner than authorities had previously suggested."
" In the meantime, the recovery of the victims' personal belongings will start Wednesday, Menichini said."
" Among those personal belongings could be more cell phones belonging to the 144 passengers and six crew"
" on board. Check out the latest from our correspondents . The details about Lubitz's correspondence with"
" the flight school during his training were among several developments as investigators continued to"
" delve into what caused the crash and Lubitz's possible motive for downing the jet. A Lufthansa"
" spokesperson told CNN on Tuesday that Lubitz had a valid medical certificate, had passed all his"
' examinations and "held all the licenses required." Earlier, a spokesman for the prosecutor\'s office in'
" Dusseldorf, Christoph Kumpa, said medical records reveal Lubitz suffered from suicidal tendencies at"
" some point before his aviation career and underwent psychotherapy before he got his pilot's license."
" Kumpa emphasized there's no evidence suggesting Lubitz was suicidal or acting aggressively before the"
" crash. Investigators are looking into whether Lubitz feared his medical condition would cause him to"
" lose his pilot's license, a European government official briefed on the investigation told CNN on"
' Tuesday. While flying was "a big part of his life," the source said, it\'s only one theory being'
" considered. Another source, a law enforcement official briefed on the investigation, also told CNN that"
" authorities believe the primary motive for Lubitz to bring down the plane was that he feared he would"
" not be allowed to fly because of his medical problems. Lubitz's girlfriend told investigators he had"
" seen an eye doctor and a neuropsychologist, both of whom deemed him unfit to work recently and concluded"
" he had psychological issues, the European government official said. But no matter what details emerge"
" about his previous mental health struggles, there's more to the story, said Brian Russell, a forensic"
' psychologist. "Psychology can explain why somebody would turn rage inward on themselves about the fact'
" that maybe they weren't going to keep doing their job and they're upset about that and so they're"
' suicidal," he said. "But there is no mental illness that explains why somebody then feels entitled to'
" also take that rage and turn it outward on 149 other people who had nothing to do with the person's"
' problems." Germanwings crash compensation: What we know . Who was the captain of Germanwings Flight'

" (CNN)The Palestinian Authority officially became the 123rd member of the International Criminal Court on"
" Wednesday, a step that gives the court jurisdiction over alleged crimes in Palestinian territories. The"
" formal accession was marked with a ceremony at The Hague, in the Netherlands, where the court is based."
" The Palestinians signed the ICC's founding Rome Statute in January, when they also accepted its"
' jurisdiction over alleged crimes committed "in the occupied Palestinian territory, including East'
' Jerusalem, since June 13, 2014." Later that month, the ICC opened a preliminary examination into the'
" situation in Palestinian territories, paving the way for possible war crimes investigations against"
" Israelis. As members of the court, Palestinians may be subject to counter-charges as well. Israel and"
" the United States, neither of which is an ICC member, opposed the Palestinians' efforts to join the"
" body. But Palestinian Foreign Minister Riad al-Malki, speaking at Wednesday's ceremony, said it was a"
' move toward greater justice. "As Palestine formally becomes a State Party to the Rome Statute today, the'
' world is also a step closer to ending a long era of impunity and injustice," he said, according to an'
' ICC news release. "Indeed, today brings us closer to our shared goals of justice and peace." Judge'
" Kuniko Ozaki, a vice president of the ICC, said acceding to the treaty was just the first step for the"
' Palestinians. "As the Rome Statute today enters into force for the State of Palestine, Palestine'
" acquires all the rights as well as responsibilities that come with being a State Party to the Statute."
' These are substantive commitments, which cannot be taken lightly," she said. Rights group Human Rights'
' Watch welcomed the development. "Governments seeking to penalize Palestine for joining the ICC should'
" immediately end their pressure, and countries that support universal acceptance of the court's treaty"
' should speak out to welcome its membership," said Balkees Jarrah, international justice counsel for the'
" group. \"What's objectionable is the attempts to undermine international justice, not Palestine's"
' decision to join a treaty to which over 100 countries around the world are members." In January, when'
" the preliminary ICC examination was opened, Israeli Prime Minister Benjamin Netanyahu described it as an"
' outrage, saying the court was overstepping its boundaries. The United States also said it "strongly"'
" disagreed with the court's decision. \"As we have said repeatedly, we do not believe that Palestine is a"
' state and therefore we do not believe that it is eligible to join the ICC," the State Department said in'
' a statement. It urged the warring sides to resolve their differences through direct negotiations. "We'
' will continue to oppose actions against Israel at the ICC as counterproductive to the cause of peace,"'
" it said. But the ICC begs to differ with the definition of a state for its purposes and refers to the"
' territories as "Palestine." While a preliminary examination is not a formal investigation, it allows the'
" court to review evidence and determine whether to investigate suspects on both sides. Prosecutor Fatou"
' Bensouda said her office would "conduct its analysis in full independence and impartiality." The war'
" between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The inquiry"
" will include alleged war crimes committed since June. The International Criminal Court was set up in"

" (CNN)The United States and its negotiating partners reached a very strong framework agreement with Iran"
" in Lausanne, Switzerland, on Thursday that limits Iran's nuclear program in such a way as to effectively"
" block it from building a nuclear weapon. Expect pushback anyway, if the recent past is any harbinger."
" Just last month, in an attempt to head off such an agreement, House Speaker John Boehner invited Israeli"
" Prime Minister Benjamin Netanyahu to preemptively blast it before Congress, and 47 senators sent a"
" letter to the Iranian leadership warning them away from a deal. The debate that has already begun since"
" the announcement of the new framework will likely result in more heat than light. It will not be helped"
" by the gathering swirl of dubious assumptions and doubtful assertions. Let us address some of these: ."
" The most misleading assertion, despite universal rejection by experts, is that the negotiations'"
" objective at the outset was the total elimination of any nuclear program in Iran. That is the position"
" of Netanyahu and his acolytes in the U.S. Congress. But that is not and never was the objective. If it"
" had been, there would have been no Iranian team at the negotiating table. Rather, the objective has"
" always been to structure an agreement or series of agreements so that Iran could not covertly develop a"
" nuclear arsenal before the United States and its allies could respond. The new framework has exceeded"
" expectations in achieving that goal. It would reduce Iran's low-enriched uranium stockpile, cut by"
" two-thirds its number of installed centrifuges and implement a rigorous inspection regime. Another"
" dubious assumption of opponents is that the Iranian nuclear program is a covert weapons program. Despite"
" sharp accusations by some in the United States and its allies, Iran denies having such a program, and"
" U.S. intelligence contends that Iran has not yet made the decision to build a nuclear weapon. Iran's"
" continued cooperation with International Atomic Energy Agency inspections is further evidence on this"
" point, and we'll know even more about Iran's program in the coming months and years because of the deal."
" In fact, the inspections provisions that are part of this agreement are designed to protect against any"
" covert action by the Iranians. What's more, the rhetoric of some members of Congress has implied that"
" the negotiations have been between only the United States and Iran (i.e., the 47 senators' letter"
" warning that a deal might be killed by Congress or a future president). This of course is not the case."
" The talks were between Iran and the five permanent members of the U.N. Security Council (United States,"
" United Kingdom, France, China and Russia) plus Germany, dubbed the P5+1. While the United States has"
" played a leading role in the effort, it negotiated the terms alongside its partners. If the agreement"
" reached by the P5+1 is rejected by Congress, it could result in an unraveling of the sanctions on Iran"
" and threaten NATO cohesion in other areas. Another questionable assertion is that this agreement"
" contains a sunset clause, after which Iran will be free to do as it pleases. Again, this is not the"
" case. Some of the restrictions on Iran's nuclear activities, such as uranium enrichment, will be eased"
" or eliminated over time, as long as 15 years. But most importantly, the framework agreement includes"

" French Alps. All 150 on board were killed. Paris Match and Bild reported that the video was"
" recovered from a phone at the wreckage site. The two publications described the supposed video, but"
" did not post it on their websites. The publications said that they watched the video, which was"
" found by a source close to the investigation. \"One can hear cries of 'My God' in several"

" of the pilot trying to open the cockpit door with a heavy object. Towards the end, after a heavy"
' shake, stronger than the others, the screaming intensifies. Then nothing." "It is a very disturbing'

" in Rosny sous-Bois, near Paris, in order to be analyzed by specialized technicians working"
" hand-in-hand with investigators. But none of the cell phones found so far have been sent to the"

" something we did not know before. ... Overall we can say many things of the investigation weren't"
' revealed by the investigation at the beginning," he said. What was mental state of Germanwings'
" co-pilot? German airline Lufthansa confirmed Tuesday that co-pilot Andreas Lubitz had battled"
" depression years before he took the controls of Germanwings Flight 9525, which he's accused of"
" deliberately crashing last week in the French Alps. Lubitz told his Lufthansa flight training school"
' in 2009 that he had a "previous episode of severe depression," the airline said Tuesday. Email'
" correspondence between Lubitz and the school discovered in an internal investigation, Lufthansa"
" said, included medical documents he submitted in connection with resuming his flight training. The"
" announcement indicates that Lufthansa, the parent company of Germanwings, knew of Lubitz's battle"
" with depression, allowed him to continue training and ultimately put him in the cockpit. Lufthansa,"
" whose CEO Carsten Spohr previously said Lubitz was 100% fit to fly, described its statement Tuesday"
' as a "swift and seamless clarification" and said it was sharing the information and documents --'
" including training and medical records -- with public prosecutors. Spohr traveled to the crash site"
" Wednesday, where recovery teams have been working for the past week to recover human remains and"
" plane debris scattered across a steep mountainside. He saw the crisis center set up in"
" Seyne-les-Alpes, laid a wreath in the village of Le Vernet, closer to the crash site, where grieving"
" families have left flowers at a simple stone memorial. Menichini told CNN late Tuesday that no"
" visible human remains were left at the site but recovery teams would keep searching. French"
" President Francois Hollande, speaking Tuesday, said that it should be possible to identify all the"
" victims using DNA analysis by the end of the week, sooner than authorities had previously suggested."
" In the meantime, the recovery of the victims' personal belongings will start Wednesday, Menichini"
" said. Among those personal belongings could be more cell phones belonging to the 144 passengers and"
" six crew on board. Check out the latest from our correspondents . The details about Lubitz's"
" correspondence with the flight school during his training were among several developments as"
" investigators continued to delve into what caused the crash and Lubitz's possible motive for"
" downing the jet. A Lufthansa spokesperson told CNN on Tuesday that Lubitz had a valid medical"
' certificate, had passed all his examinations and "held all the licenses required." Earlier, a'
" spokesman for the prosecutor's office in Dusseldorf, Christoph Kumpa, said medical records reveal"
" Lubitz suffered from suicidal tendencies at some point before his aviation career and underwent"
" psychotherapy before he got his pilot's license. Kumpa emphasized there's no evidence suggesting"
" Lubitz was suicidal or acting aggressively before the crash. Investigators are looking into whether"
" Lubitz feared his medical condition would cause him to lose his pilot's license, a European"
' government official briefed on the investigation told CNN on Tuesday. While flying was "a big part'
" of his life,\" the source said, it's only one theory being considered. Another source, a law"
" enforcement official briefed on the investigation, also told CNN that authorities believe the"
" primary motive for Lubitz to bring down the plane was that he feared he would not be allowed to fly"
" because of his medical problems. Lubitz's girlfriend told investigators he had seen an eye doctor"
" and a neuropsychologist, both of whom deemed him unfit to work recently and concluded he had"
" psychological issues, the European government official said. But no matter what details emerge about"
" his previous mental health struggles, there's more to the story, said Brian Russell, a forensic"
' psychologist. "Psychology can explain why somebody would turn rage inward on themselves about the'
" fact that maybe they weren't going to keep doing their job and they're upset about that and so"
' they\'re suicidal," he said. "But there is no mental illness that explains why somebody then feels'

"The Palestinian Authority officially became the 123rd member of the International Criminal Court on"
" Wednesday, a step that gives the court jurisdiction over alleged crimes in Palestinian territories."
" The formal accession was marked with a ceremony at The Hague, in the Netherlands, where the court is"
" based. The Palestinians signed the ICC's founding Rome Statute in January, when they also accepted"
' its jurisdiction over alleged crimes committed "in the occupied Palestinian territory, including'
' East Jerusalem, since June 13, 2014." Later that month, the ICC opened a preliminary examination'
" into the situation in Palestinian territories, paving the way for possible war crimes investigations"
" against Israelis. As members of the court, Palestinians may be subject to counter-charges as well."
" Israel and the United States, neither of which is an ICC member, opposed the Palestinians' efforts"
" to join the body. But Palestinian Foreign Minister Riad al-Malki, speaking at Wednesday's ceremony,"
' said it was a move toward greater justice. "As Palestine formally becomes a State Party to the Rome'
' Statute today, the world is also a step closer to ending a long era of impunity and injustice," he'
' said, according to an ICC news release. "Indeed, today brings us closer to our shared goals of'
' justice and peace." Judge Kuniko Ozaki, a vice president of the ICC, said acceding to the treaty was'
' just the first step for the Palestinians. "As the Rome Statute today enters into force for the State'
" of Palestine, Palestine acquires all the rights as well as responsibilities that come with being a"
' State Party to the Statute. These are substantive commitments, which cannot be taken lightly," she'
' said. Rights group Human Rights Watch welcomed the development. "Governments seeking to penalize'
" Palestine for joining the ICC should immediately end their pressure, and countries that support"
" universal acceptance of the court's treaty should speak out to welcome its membership,\" said"
" Balkees Jarrah, international justice counsel for the group. \"What's objectionable is the attempts"
" to undermine international justice, not Palestine's decision to join a treaty to which over 100"
' countries around the world are members." In January, when the preliminary ICC examination was'
" opened, Israeli Prime Minister Benjamin Netanyahu described it as an outrage, saying the court was"
' overstepping its boundaries. The United States also said it "strongly" disagreed with the court\'s'
' decision. "As we have said repeatedly, we do not believe that Palestine is a state and therefore we'
' do not believe that it is eligible to join the ICC," the State Department said in a statement. It'
' urged the warring sides to resolve their differences through direct negotiations. "We will continue'
' to oppose actions against Israel at the ICC as counterproductive to the cause of peace," it said.'
" But the ICC begs to differ with the definition of a state for its purposes and refers to the"
' territories as "Palestine." While a preliminary examination is not a formal investigation, it allows'
" the court to review evidence and determine whether to investigate suspects on both sides. Prosecutor"
' Fatou Bensouda said her office would "conduct its analysis in full independence and impartiality."'
" The war between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The"
" inquiry will include alleged war crimes committed since June. The International Criminal Court was"
" set up in 2002 to prosecute genocide, crimes against humanity and war crimes.",
"The French prosecutor leading an investigation into the crash of Germanwings Flight 9525 insisted"
" Wednesday that he was not aware of any video footage from on board the plane. Marseille prosecutor"
' Brice Robin told CNN that "so far no videos were used in the crash investigation." He added, "A'
" person who has such a video needs to immediately give it to the investigators.\" Robin's comments"
" follow claims by two magazines, German daily Bild and French Paris Match, of a cell phone video"
" showing the harrowing final seconds from on board Germanwings Flight 9525 as it crashed into the"
" French Alps. All 150 on board were killed. Paris Match and Bild reported that the video was"
" recovered from a phone at the wreckage site. The two publications described the supposed video, but"
" did not post it on their websites. The publications said that they watched the video, which was"
" found by a source close to the investigation. \"One can hear cries of 'My God' in several"
' languages," Paris Match reported. "Metallic banging can also be heard more than three times, perhaps'
" of the pilot trying to open the cockpit door with a heavy object. Towards the end, after a heavy"
' shake, stronger than the others, the screaming intensifies. Then nothing." "It is a very disturbing'
" scene,\" said Julian Reichelt, editor-in-chief of Bild online. An official with France's accident"
" investigation agency, the BEA, said the agency is not aware of any such video. Lt. Col. Jean-Marc"
" Menichini, a French Gendarmerie spokesman in charge of communications on rescue efforts around the"
' Germanwings crash site, told CNN that the reports were "completely wrong" and "unwarranted." Cell'
' phones have been collected at the site, he said, but that they "hadn\'t been exploited yet."'
" Menichini said he believed the cell phones would need to be sent to the Criminal Research Institute"
" in Rosny sous-Bois, near Paris, in order to be analyzed by specialized technicians working"
" hand-in-hand with investigators. But none of the cell phones found so far have been sent to the"
" institute, Menichini said. Asked whether staff involved in the search could have leaked a memory"
' card to the media, Menichini answered with a categorical "no." Reichelt told "Erin Burnett:'
' Outfront" that he had watched the video and stood by the report, saying Bild and Paris Match are'
' "very confident" that the clip is real. He noted that investigators only revealed they\'d recovered'
' cell phones from the crash site after Bild and Paris Match published their reports. "That is'
" something we did not know before. ... Overall we can say many things of the investigation weren't"
' revealed by the investigation at the beginning," he said. What was mental state of Germanwings'
" co-pilot? German airline Lufthansa confirmed Tuesday that co-pilot Andreas Lubitz had battled"
" depression years before he took the controls of Germanwings Flight 9525, which he's accused of"
" deliberately crashing last week in the French Alps. Lubitz told his Lufthansa flight training school"
' in 2009 that he had a "previous episode of severe depression," the airline said Tuesday. Email'
" correspondence between Lubitz and the school discovered in an internal investigation, Lufthansa"
" said, included medical documents he submitted in connection with resuming his flight training. The"
" announcement indicates that Lufthansa, the parent company of Germanwings, knew of Lubitz's battle"
" with depression, allowed him to continue training and ultimately put him in the cockpit. Lufthansa,"
" whose CEO Carsten Spohr previously said Lubitz was 100% fit to fly, described its statement Tuesday"
' as a "swift and seamless clarification" and said it was sharing the information and documents --'
" including training and medical records -- with public prosecutors. Spohr traveled to the crash site"
" Wednesday, where recovery teams have been working for the past week to recover human remains and"
" plane debris scattered across a steep mountainside. He saw the crisis center set up in"
" Seyne-les-Alpes, laid a wreath in the village of Le Vernet, closer to the crash site, where grieving"
" families have left flowers at a simple stone memorial. Menichini told CNN late Tuesday that no"
" visible human remains were left at the site but recovery teams would keep searching. French"
" President Francois Hollande, speaking Tuesday, said that it should be possible to identify all the"
" victims using DNA analysis by the end of the week, sooner than authorities had previously suggested."
" In the meantime, the recovery of the victims' personal belongings will start Wednesday, Menichini"
" said. Among those personal belongings could be more cell phones belonging to the 144 passengers and"
" six crew on board. Check out the latest from our correspondents . The details about Lubitz's"
" correspondence with the flight school during his training were among several developments as"
" investigators continued to delve into what caused the crash and Lubitz's possible motive for"
" downing the jet. A Lufthansa spokesperson told CNN on Tuesday that Lubitz had a valid medical"
' certificate, had passed all his examinations and "held all the licenses required." Earlier, a'
" spokesman for the prosecutor's office in Dusseldorf, Christoph Kumpa, said medical records reveal"
" Lubitz suffered from suicidal tendencies at some point before his aviation career and underwent"
" psychotherapy before he got his pilot's license. Kumpa emphasized there's no evidence suggesting"
" Lubitz was suicidal or acting aggressively before the crash. Investigators are looking into whether"
" Lubitz feared his medical condition would cause him to lose his pilot's license, a European"
' government official briefed on the investigation told CNN on Tuesday. While flying was "a big part'
" of his life,\" the source said, it's only one theory being considered. Another source, a law"
" enforcement official briefed on the investigation, also told CNN that authorities believe the"
" primary motive for Lubitz to bring down the plane was that he feared he would not be allowed to fly"
" because of his medical problems. Lubitz's girlfriend told investigators he had seen an eye doctor"
" and a neuropsychologist, both of whom deemed him unfit to work recently and concluded he had"
" psychological issues, the European government official said. But no matter what details emerge about"
" his previous mental health struggles, there's more to the story, said Brian Russell, a forensic"
' psychologist. "Psychology can explain why somebody would turn rage inward on themselves about the'
" fact that maybe they weren't going to keep doing their job and they're upset about that and so"
' they\'re suicidal," he said. "But there is no mental illness that explains why somebody then feels'
" entitled to also take that rage and turn it outward on 149 other people who had nothing to do with"

# Training customization
TRL is designed with modularity in mind so that users to be able to efficiently customize the training loop for their needs. Below are some examples on how you can apply and test different techniques.
## Train on multiple GPUs / nodes
The trainers in TRL use 🤗 Accelerate to enable distributed training across multiple GPUs or nodes. To do so, first create an 🤗 Accelerate config file by running
```bash
accelerate config
```
and answering the questions according to your multi-gpu / multi-node setup. You can then launch distributed training by running:
```bash
accelerate launch your_script.py
```
We also provide config files in the [examples folder](https://github.com/huggingface/trl/tree/main/examples/accelerate_configs) that can be used as templates. To use these templates, simply pass the path to the config file when launching a job, e.g.:
```shell
accelerate launch --config_file=examples/accelerate_configs/multi_gpu.yaml --num_processes {NUM_GPUS} path_to_script.py --all_arguments_of_the_script
```
Refer to the [examples page](https://github.com/huggingface/trl/tree/main/examples) for more details.
### Distributed training with DeepSpeed
All of the trainers in TRL can be run on multiple GPUs together with DeepSpeed ZeRO-{1,2,3} for efficient sharding of the optimizer states, gradients, and model weights. To do so, run:
```shell
accelerate launch --config_file=examples/accelerate_configs/deepspeed_zero{1,2,3}.yaml --num_processes {NUM_GPUS} path_to_your_script.py --all_arguments_of_the_script
```
Note that for ZeRO-3, a small tweak is needed to initialize your reward model on the correct device via the `zero3_init_context_manager()` context manager. In particular, this is needed to avoid DeepSpeed hanging after a fixed number of training steps. Here is a snippet of what is involved from the [`sentiment_tuning`](https://github.com/huggingface/trl/blob/main/examples/scripts/ppo.py) example:
```python
ds_plugin = ppo_trainer.accelerator.state.deepspeed_plugin
if ds_plugin is not None and ds_plugin.is_zero3_init_enabled():
with ds_plugin.zero3_init_context_manager(enable=False):
sentiment_pipe = pipeline("sentiment-analysis", model="lvwerra/distilbert-imdb", device=device)
else:
sentiment_pipe = pipeline("sentiment-analysis", model="lvwerra/distilbert-imdb", device=device)
```
Consult the 🤗 Accelerate [documentation](https://huggingface.co/docs/accelerate/usage_guides/deepspeed) for more information about the DeepSpeed plugin.
## Use different optimizers
By default, the `PPOTrainer` creates a `torch.optim.Adam` optimizer. You can create and define a different optimizer and pass it to `PPOTrainer`:
```python
import torch
from transformers import GPT2Tokenizer
from trl import PPOTrainer, PPOConfig, AutoModelForCausalLMWithValueHead
# 1. load a pretrained model
model = AutoModelForCausalLMWithValueHead.from_pretrained('gpt2')
ref_model = AutoModelForCausalLMWithValueHead.from_pretrained('gpt2')
tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
# 2. define config
ppo_config = {'batch_size': 1, 'learning_rate':1e-5}
config = PPOConfig(**ppo_config)
# 2. Create optimizer
optimizer = torch.optim.SGD(model.parameters(), lr=config.learning_rate)
# 3. initialize trainer
ppo_trainer = PPOTrainer(config, model, ref_model, tokenizer, optimizer=optimizer)
```
For memory efficient fine-tuning, you can also pass `Adam8bit` optimizer from `bitsandbytes`:
```python
import torch
import bitsandbytes as bnb
from transformers import GPT2Tokenizer
from trl import PPOTrainer, PPOConfig, AutoModelForCausalLMWithValueHead
# 1. load a pretrained model
model = AutoModelForCausalLMWithValueHead.from_pretrained('gpt2')
ref_model = AutoModelForCausalLMWithValueHead.from_pretrained('gpt2')
tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
# 2. define config
ppo_config = {'batch_size': 1, 'learning_rate':1e-5}
config = PPOConfig(**ppo_config)
# 2. Create optimizer
optimizer = bnb.optim.Adam8bit(model.parameters(), lr=config.learning_rate)
# 3. initialize trainer
ppo_trainer = PPOTrainer(config, model, ref_model, tokenizer, optimizer=optimizer)
```
### Use LION optimizer
You can use the new [LION optimizer from Google](https://huggingface.co/papers/2302.06675) as well, first take the source code of the optimizer definition [here](https://github.com/lucidrains/lion-pytorch/blob/main/lion_pytorch/lion_pytorch.py), and copy it so that you can import the optimizer. Make sure to initialize the optimizer by considering the trainable parameters only for a more memory efficient training:
```python
optimizer = Lion(filter(lambda p: p.requires_grad, self.model.parameters()), lr=self.config.learning_rate)
...
ppo_trainer = PPOTrainer(config, model, ref_model, tokenizer, optimizer=optimizer)
```
We advise you to use the learning rate that you would use for `Adam` divided by 3 as pointed out [here](https://github.com/lucidrains/lion-pytorch#lion---pytorch). We observed an improvement when using this optimizer compared to classic Adam (check the full logs [here](https://wandb.ai/distill-bloom/trl/runs/lj4bheke?workspace=user-younesbelkada)):
<div style="text-align: center">
<img src="https://huggingface.co/datasets/trl-internal-testing/example-images/resolve/main/images/trl-lion.png">
</div>
## Add a learning rate scheduler
You can also play with your training by adding learning rate schedulers!
```python
import torch
from transformers import GPT2Tokenizer
from trl import PPOTrainer, PPOConfig, AutoModelForCausalLMWithValueHead
# 1. load a pretrained model
model = AutoModelForCausalLMWithValueHead.from_pretrained('gpt2')
ref_model = AutoModelForCausalLMWithValueHead.from_pretrained('gpt2')
tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
# 2. define config
ppo_config = {'batch_size': 1, 'learning_rate':1e-5}
config = PPOConfig(**ppo_config)
# 2. Create optimizer
optimizer = torch.optim.SGD(model.parameters(), lr=config.learning_rate)
lr_scheduler = torch.optim.lr_scheduler.ExponentialLR(optimizer, gamma=0.9)
# 3. initialize trainer
ppo_trainer = PPOTrainer(config, model, ref_model, tokenizer, optimizer=optimizer, lr_scheduler=lr_scheduler)
```
## Memory efficient fine-tuning by sharing layers
Another tool you can use for more memory efficient fine-tuning is to share layers between the reference model and the model you want to train.
```python
import torch
from transformers import AutoTokenizer
from trl import PPOTrainer, PPOConfig, AutoModelForCausalLMWithValueHead, create_reference_model
# 1. load a pretrained model
model = AutoModelForCausalLMWithValueHead.from_pretrained('bigscience/bloom-560m')
ref_model = create_reference_model(model, num_shared_layers=6)
tokenizer = AutoTokenizer.from_pretrained('bigscience/bloom-560m')
# 2. initialize trainer
ppo_config = {'batch_size': 1}
config = PPOConfig(**ppo_config)
ppo_trainer = PPOTrainer(config, model, ref_model, tokenizer)
```
## Pass 8-bit reference models
<div>
Since `trl` supports all key word arguments when loading a model from `transformers` using `from_pretrained`, you can also leverage `load_in_8bit` from `transformers` for more memory efficient fine-tuning.
Read more about 8-bit model loading in `transformers` [here](https://huggingface.co/docs/transformers/perf_infer_gpu_one#bitsandbytes-integration-for-int8-mixedprecision-matrix-decomposition).
</div>
```python
# 0. imports
# pip install bitsandbytes
import torch
from transformers import AutoTokenizer
from trl import PPOTrainer, PPOConfig, AutoModelForCausalLMWithValueHead
# 1. load a pretrained model
model = AutoModelForCausalLMWithValueHead.from_pretrained('bigscience/bloom-560m')
ref_model = AutoModelForCausalLMWithValueHead.from_pretrained('bigscience/bloom-560m', device_map="auto", load_in_8bit=True)
tokenizer = AutoTokenizer.from_pretrained('bigscience/bloom-560m')
# 2. initialize trainer
ppo_config = {'batch_size': 1}
config = PPOConfig(**ppo_config)
ppo_trainer = PPOTrainer(config, model, ref_model, tokenizer)
```
## Use the CUDA cache optimizer
When training large models, you should better handle the CUDA cache by iteratively clearing it. Do do so, simply pass `optimize_cuda_cache=True` to `PPOConfig`:
```python
config = PPOConfig(..., optimize_cuda_cache=True)
```
## Use score scaling/normalization/clipping
As suggested by [Secrets of RLHF in Large Language Models Part I: PPO](https://huggingface.co/papers/2307.04964), we support score (aka reward) scaling/normalization/clipping to improve training stability via `PPOConfig`:
```python
from trl import PPOConfig
ppo_config = {
use_score_scaling=True,
use_score_norm=True,
score_clip=0.5,
}
config = PPOConfig(**ppo_config)
```
To run `ppo.py`, you can use the following command:
```
python examples/scripts/ppo.py --log_with wandb --use_score_scaling --use_score_norm --score_clip 0.5
```

**TRL CHAT INTERFACE**
The chat interface is a simple tool to try out a chat model.
Besides talking to the model there are several commands:
- **clear**: clears the current conversation and start a new one
- **example {NAME}**: load example named `{NAME}` from the config and use it as the user input
- **set {SETTING_NAME}={SETTING_VALUE};**: change the system prompt or generation settings (multiple settings are separated by a ';').
- **reset**: same as clear but also resets the generation configs to defaults if they have been changed by **set**
- **save {SAVE_NAME} (optional)**: save the current chat and settings to file by default to `./chat_history/{MODEL_NAME}/chat_{DATETIME}.yaml` or `{SAVE_NAME}` if provided
- **exit**: closes the interface

train_dataset (`datasets.Dataset`):
The dataset to use for training.
eval_dataset (`datasets.Dataset`):

The model initializer to use for training. If None is specified, the default model initializer will be used.
callbacks (`List[transformers.TrainerCallback]`):

The optimizer and scheduler to use for training.
preprocess_logits_for_metrics (`Callable[[torch.Tensor, torch.Tensor], torch.Tensor]`):
The function to use to preprocess the logits before computing the metrics.
peft_config (`Dict`, defaults to `None`):
The PEFT configuration to use for training. If you pass a PEFT configuration, the model will be wrapped in a PEFT model.
disable_dropout (`bool`, defaults to `True`):
Whether or not to disable dropouts in `model` and `ref_model`.
compute_metrics (`Callable[[EvalPrediction], Dict]`, *optional*):
The function to use to compute the metrics. Must take a `EvalPrediction` and return
a dictionary string to metric values.
model_adapter_name (`str`, defaults to `None`):
Name of the train target PEFT adapter, when using LoRA with multiple adapters.

# Installation and Configuration
Before you start, you will need to setup your environment, install the appropriate packages, and configure 🤗 Accelerate. 🤗 Accelerate is tested on **Python 3.8+**.
## Installing 🤗 Accelerate
🤗 Accelerate is available on pypi and conda, as well as on GitHub. Details to install from each are below:
### pip
To install 🤗 Accelerate from pypi, perform:
```bash
pip install accelerate
```
### conda
🤗 Accelerate can also be installed with conda with:
```bash
conda install -c conda-forge accelerate
```
### Source
New features are added every day that haven't been released yet. To try them out yourself, install
from the GitHub repository:
```bash
pip install git+https://github.com/huggingface/accelerate
```
If you're working on contributing to the library or wish to play with the source code and see live
results as you run the code, an editable version can be installed from a locally-cloned version of the
repository:
```bash
git clone https://github.com/huggingface/accelerate
cd accelerate
pip install -e .
```
## Configuring 🤗 Accelerate
After installing, you need to configure 🤗 Accelerate for how the current system is setup for training.
To do so run the following and answer the questions prompted to you:
```bash
accelerate config
```
To write a barebones configuration that doesn't include options such as DeepSpeed configuration or running on TPUs, you can quickly run:
```bash
python -c "from accelerate.utils import write_basic_config; write_basic_config(mixed_precision='fp16')"
```
🤗 Accelerate will automatically utilize the maximum number of GPUs available and set the mixed precision mode.
To check that your configuration looks fine, run:
```bash
accelerate env
```
An example output is shown below, which describes two GPUs on a single machine with no mixed precision being used:
```bash
- `Accelerate` version: 0.11.0.dev0
- Platform: Linux-5.10.0-15-cloud-amd64-x86_64-with-debian-11.3
- Python version: 3.7.12
- Numpy version: 1.19.5
- PyTorch version (GPU?): 1.12.0+cu102 (True)
- `Accelerate` default config:
- compute_environment: LOCAL_MACHINE
- distributed_type: MULTI_GPU
- mixed_precision: no
- use_cpu: False
- num_processes: 2
- machine_rank: 0
- num_machines: 1
- main_process_ip: None
- main_process_port: None
- main_training_function: main
- deepspeed_config: {}
- fsdp_config: {}

# Accelerated PyTorch Training on Mac
With PyTorch v1.12 release, developers and researchers can take advantage of Apple silicon GPUs for significantly faster model training.
This unlocks the ability to perform machine learning workflows like prototyping and fine-tuning locally, right on Mac.
Apple's Metal Performance Shaders (MPS) as a backend for PyTorch enables this and can be used via the new `"mps"` device.
This will map computational graphs and primitives on the MPS Graph framework and tuned kernels provided by MPS.
For more information please refer official documents [Introducing Accelerated PyTorch Training on Mac](https://pytorch.org/blog/introducing-accelerated-pytorch-training-on-mac/)
and [MPS BACKEND](https://pytorch.org/docs/stable/notes/mps.html).
### Benefits of Training and Inference using Apple Silicon Chips
1. Enables users to train larger networks or batch sizes locally
2. Reduces data retrieval latency and provides the GPU with direct access to the full memory store due to unified memory architecture.
Therefore, improving end-to-end performance.
3. Reduces costs associated with cloud-based development or the need for additional local GPUs.
**Pre-requisites**: To install torch with mps support,
please follow this nice medium article [GPU-Acceleration Comes to PyTorch on M1 Macs](https://medium.com/towards-data-science/gpu-acceleration-comes-to-pytorch-on-m1-macs-195c399efcc1).
## How it works out of the box
It is enabled by default on MacOs machines with MPS enabled Apple Silicon GPUs.
To disable it, pass `--cpu` flag to `accelerate launch` command or answer the corresponding question when answering the `accelerate config` questionnaire.
You can directly run the following script to test it out on MPS enabled Apple Silicon machines:
```bash
accelerate launch /examples/cv_example.py --data_dir images
```
## A few caveats to be aware of
1. We strongly recommend to install PyTorch >= 1.13 (nightly version at the time of writing) on your MacOS machine.
It has major fixes related to model correctness and performance improvements for transformer based models.
Please refer to https://github.com/pytorch/pytorch/issues/82707 for more details.
2. Distributed setups `gloo` and `nccl` are not working with `mps` device.
This means that currently only single GPU of `mps` device type can be used.
Finally, please, remember that, 🤗 `Accelerate` only integrates MPS backend, therefore if you
have any problems or questions with regards to MPS backend usage, please, file an issue with [PyTorch GitHub](https://github.com/pytorch/pytorch/issues). | accelerate/docs/source/usage_guides/mps.md/0 | {

//! #A simplified example in Rust of training a neural network and then using it based on the Candle Framework by Hugging Face.
//! Author: Evgeny Igumnov 2023 [email protected]
//! This program implements a neural network to predict the winner of the second round of elections based on the results of the first round.
//!
//! ##Basic moments:
//!
//! A multilayer perceptron with two hidden layers is used. The first hidden layer has 4 neurons, the second has 2 neurons.
//! The input is a vector of 2 numbers - the percentage of votes for the first and second candidates in the first stage.
//! The output is the number 0 or 1, where 1 means that the first candidate will win in the second stage, 0 means that he will lose.
//! For training, samples with real data on the results of the first and second stages of different elections are used.
//! The model is trained by backpropagation using gradient descent and the cross-entropy loss function.
//! Model parameters (weights of neurons) are initialized randomly, then optimized during training.
//! After training, the model is tested on a deferred sample to evaluate the accuracy.
//! If the accuracy on the test set is below 100%, the model is considered underfit and the learning process is repeated.
//! Thus, this neural network learns to find hidden relationships between the results of the first and second rounds of voting in order to make predictions for new data.

# candle-based
Experimental, not instruction-tuned small LLM from the Hazy Research group, combining local and linear attention layers.
[Blogpost](https://hazyresearch.stanford.edu/blog/2024-03-03-based)
[Simple linear attention language models balance the recall-throughput tradeoff](https://arxiv.org/abs/2402.18668)
## Running an example
```bash
$ cargo run --example based --release -- --prompt "Flying monkeys are" --which 1b-50b --sample-len 100
Flying monkeys are a common sight in the wild, but they are also a threat to humans.
The new study, published today (July 31) in the journal Science Advances, shows that the monkeys are using their brains to solve the problem of how to get around the problem.
"We found that the monkeys were using a strategy called 'cognitive mapping' - they would use their brains to map out the route ahead," says lead author Dr. David J. Smith from the University of California

# candle-gemma: 2b and 7b LLMs from Google DeepMind
[Gemma](https://ai.google.dev/gemma/docs) is a collection of lightweight open
models published by Google Deepmind with a 2b and a 7b variant for the first
version, and a 2b and a 9b variant for v2.
## Running the example
```bash
$ cargo run --example gemma --features cuda -r -- \
--prompt "Here is a proof that square root of 2 is not rational: "
Here is a proof that square root of 2 is not rational:
Let us assume it to be rational. Then, we can write √2 = p/q where q ≠ 0 and p and q are integers with no common factors other than 1. Squaring both sides gives us (p/q)^2 = 2 or p^2/q^2 = 2. This implies that p^2 is divisible by 2, which means that p must be even. Let us write p = 2m where m is an integer. Substituting this in the above equation we get:
(p^2)/q^2 = 2 or (4m^2)/q^2 = 2 or q^2/2m^2 = 1 which implies that q^2 must be divisible by 2, and hence q is even. This contradicts our assumption that p and q have no common factors other than 1. Hence we conclude that √2 cannot be rational.
```

# candle-yolo-v8: Object Detection and Pose Estimation
This is a port of [Ultralytics
YOLOv8](https://github.com/ultralytics/ultralytics). The implementation is based
on the [tinygrad
version](https://github.com/tinygrad/tinygrad/blob/master/examples/yolov8.py)
and on the model architecture described in this
[issue](https://github.com/ultralytics/ultralytics/issues/189). The supported
tasks are object detection and pose estimation.
You can try this model online on the [Candle YOLOv8
Space](https://huggingface.co/spaces/lmz/candle-yolo). The model then fully runs
in your browser using WebAssembly - if you use a custom image it will never
leave your phone/computer!
## Running some example
### Object Detection
```bash
cargo run --example yolo-v8 --release -- candle-examples/examples/yolo-v8/assets/bike.jpg
```
This prints details about the detected objects and generates a `bike.pp.jpg` file.

### Pose Estimation
```bash
cargo run --example yolo-v8 --release -- \
candle-examples/examples/yolo-v8/assets/bike.jpg --task pose
```
### Command-line flags
- `--which`: select the model variant to be used, `n`, `s` , `m`, `l`, or `x` by
increasing size and quality.
- `--task`: `detect` for object detection and `pose` for pose estimation.
- `--legend-size`: the size of the characters to print.
- `--model`: use a local model file rather than downloading it from the hub.
