## Usage
|
20 |
+
|
21 |
+
```python
|
22 |
+
from transformers import AutoProcessor, AutoModelForVision2Seq
|
23 |
+
|
24 |
+
# Load the model and processor
|
25 |
+
processor = AutoProcessor.from_pretrained("Coda-Robotics/OpenVLA-ER-Select-Book-LoRA")
|
26 |
+
model = AutoModelForVision2Seq.from_pretrained("Coda-Robotics/OpenVLA-ER-Select-Book-LoRA")
|
27 |
+
|
28 |
+
# Process an image
|
29 |
+
image = ... # Load your image
|
30 |
+
inputs = processor(images=image, return_tensors="pt")
|
31 |
+
outputs = model.generate(**inputs)
|
32 |
+
text = processor.decode(outputs[0], skip_special_tokens=True)
|
33 |
+
```
|
34 |
+
|
35 |
+
|
36 |
+
## Using with PEFT
|
37 |
+
|
38 |
+
To use this adapter with the base OpenVLA model:
|
39 |
+
|
40 |
+
```python
|
41 |
+
from transformers import AutoProcessor, AutoModelForVision2Seq
|
42 |
+
from peft import PeftModel, PeftConfig
|
43 |
+
|
44 |
+
# Load the base model
|
45 |
+
base_model = AutoModelForVision2Seq.from_pretrained("openvla/openvla-7b")
|
46 |
+
|
47 |
+
# Load the LoRA adapter
|
48 |
+
adapter_model = PeftModel.from_pretrained(base_model, "{model_name}")
|
49 |
+
|
50 |
+
# Merge weights for faster inference (optional)
|
51 |
+
merged_model = adapter_model.merge_and_unload()
|
52 |
+
```
