class langchain_community.embeddings.ollama.OllamaEmbeddings[source]¶
Bases: BaseModel, Embeddings
Ollama locally runs large language models.
To use, follow the instructions at https://ollama.ai/.
Example
from langchain_community.embeddings import OllamaEmbeddings
ollama_emb = OllamaEmbeddings(
model="llama:7b",
)
r1 = ollama_emb.embed_documents(
[
"Alpha is the first letter of Greek alphabet",
"Beta is the second letter of Greek alphabet",
]
)
r2 = ollama_emb.embed_query(
"What is the second letter of Greek alphabet"
)
Create a new model by parsing and validating input data from keyword arguments.
Raises ValidationError if the input data cannot be parsed to form a valid model.
param base_url: str = 'http://localhost:11434'¶
Base url the model is hosted under.
param embed_instruction: str = 'passage: '¶
Instruction used to embed documents.
param headers: Optional[dict] = None¶
Additional headers to pass to endpoint (e.g. Authorization, Referer).
This is useful when Ollama is hosted on cloud services that require
tokens for authentication.
param mirostat: Optional[int] = None¶
Enable Mirostat sampling for controlling perplexity.
(default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0)
param mirostat_eta: Optional[float] = None¶
Influences how quickly the algorithm responds to feedback
from the generated text. A lower learning rate will result in
slower adjustments, while a higher learning rate will make | https://api.python.langchain.com/en/latest/embeddings/langchain_community.embeddings.ollama.OllamaEmbeddings.html |
8e2f15364485-1 | slower adjustments, while a higher learning rate will make
the algorithm more responsive. (Default: 0.1)
param mirostat_tau: Optional[float] = None¶
Controls the balance between coherence and diversity
of the output. A lower value will result in more focused and
coherent text. (Default: 5.0)
param model: str = 'llama2'¶
Model name to use.
param model_kwargs: Optional[dict] = None¶
Other model keyword args
param num_ctx: Optional[int] = None¶
Sets the size of the context window used to generate the
next token. (Default: 2048)
param num_gpu: Optional[int] = None¶
The number of GPUs to use. On macOS it defaults to 1 to
enable metal support, 0 to disable.
param num_thread: Optional[int] = None¶
Sets the number of threads to use during computation.
By default, Ollama will detect this for optimal performance.
It is recommended to set this value to the number of physical
CPU cores your system has (as opposed to the logical number of cores).
param query_instruction: str = 'query: '¶
Instruction used to embed the query.
param repeat_last_n: Optional[int] = None¶
Sets how far back for the model to look back to prevent
repetition. (Default: 64, 0 = disabled, -1 = num_ctx)
param repeat_penalty: Optional[float] = None¶
Sets how strongly to penalize repetitions. A higher value (e.g., 1.5)
will penalize repetitions more strongly, while a lower value (e.g., 0.9)
will be more lenient. (Default: 1.1)
param show_progress: bool = False¶ | https://api.python.langchain.com/en/latest/embeddings/langchain_community.embeddings.ollama.OllamaEmbeddings.html |
8e2f15364485-2 | param show_progress: bool = False¶
Whether to show a tqdm progress bar. Must have tqdm installed.
param stop: Optional[List[str]] = None¶
Sets the stop tokens to use.
param temperature: Optional[float] = None¶
The temperature of the model. Increasing the temperature will
make the model answer more creatively. (Default: 0.8)
param tfs_z: Optional[float] = None¶
Tail free sampling is used to reduce the impact of less probable
tokens from the output. A higher value (e.g., 2.0) will reduce the
impact more, while a value of 1.0 disables this setting. (default: 1)
param top_k: Optional[int] = None¶
Reduces the probability of generating nonsense. A higher value (e.g. 100)
will give more diverse answers, while a lower value (e.g. 10)
will be more conservative. (Default: 40)
param top_p: Optional[float] = None¶
Works together with top-k. A higher value (e.g., 0.95) will lead
to more diverse text, while a lower value (e.g., 0.5) will
generate more focused and conservative text. (Default: 0.9)

where you may want to use this Embedding class with a model name not
supported by tiktoken. This can include when using Azure embeddings or
when using one of the many model providers that expose an OpenAI-like
API but with different models. In those cases, in order to avoid erroring
when tiktoken is called, you can specify a model name to use here.

them to be under a certain limit. By default, when set to None, this will
be the same as the embedding model name. However, there are some cases
where you may want to use this Embedding class with a model name not
supported by tiktoken. This can include when using Azure embeddings or
when using one of the many model providers that expose an OpenAI-like
API but with different models. In those cases, in order to avoid erroring
when tiktoken is called, you can specify a model name to use here.

class langchain_community.embeddings.bedrock.BedrockEmbeddings[source]¶
Bases: BaseModel, Embeddings
Bedrock embedding models.
To authenticate, the AWS client uses the following methods to
automatically load credentials:
https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html
If a specific credential profile should be used, you must pass
the name of the profile from the ~/.aws/credentials file that is to be used.
Make sure the credentials / roles used have the required policies to
access the Bedrock service.
Create a new model by parsing and validating input data from keyword arguments.
Raises ValidationError if the input data cannot be parsed to form a valid model.
param client: Any = None¶
Bedrock client.
param credentials_profile_name: Optional[str] = None¶
The name of the profile in the ~/.aws/credentials or ~/.aws/config files, which
has either access keys or role information specified.
If not specified, the default credential profile or, if on an EC2 instance,
credentials from IMDS will be used.
See: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html
param endpoint_url: Optional[str] = None¶
Needed if you don’t want to default to us-east-1 endpoint
param model_id: str = 'amazon.titan-embed-text-v1'¶
Id of the model to call, e.g., amazon.titan-embed-text-v1, this is
equivalent to the modelId property in the list-foundation-models api
param model_kwargs: Optional[Dict] = None¶
Keyword arguments to pass to the model.
param normalize: bool = False¶
Whether the embeddings should be normalized to unit vectors
param region_name: Optional[str] = None¶ | https://api.python.langchain.com/en/latest/embeddings/langchain_community.embeddings.bedrock.BedrockEmbeddings.html |
