# Pixtral-12B Vision Encoder |
|
|
|
## Model Overview |
|
This repository provides direct access to the vision encoder module extracted from the Pixtral-12B multimodal model. By isolating the vision encoder, we enable researchers and developers to leverage the powerful visual feature extraction capabilities for downstream vision tasks. |
|
|
|
## Key Features |
|
- **Standalone Vision Encoder**: Extracted from the full Pixtral-12B model |
|
- **Lightweight Architecture**: Optimized 400M parameter vision encoder |
|
- **Flexible Usage**: Easily integrated into various computer vision pipelines |
|
- **No Unnecessary Decoder Weights**: Trimmed for efficient vision-specific applications |
|
|
|
## Motivation |
|
The Pixtral-12B Vision Encoder module is designed for researchers and developers who: |
|
- Require high-quality visual feature extraction |
|
- Want to use the vision encoder independently of the full multimodal model |
|
- Seek to implement custom downstream vision tasks |
|
- Desire a lightweight, efficient vision representation module |
|
|
|
## Installation |
|
```python |
|
from transformers import AutoModel |
|
import torch |
|
|
|
# Load the vision encoder |
|
vision_encoder = AutoModel.from_pretrained("your-repository/pixtral-12b-vision-encoder") |
|
``` |
|
|
|
## Example Usage |
|
```python |
|
from PIL import Image |
|
import torch |
|
|
|
# Load an image |
|
image = Image.open("example_image.jpg") |
|
|
|
# Preprocess the image (ensure to use the corresponding processor) |
|
inputs = vision_processor(images=image, return_tensors="pt") |
|
|
|
# Extract visual features |
|
with torch.no_grad(): |
|
visual_embeddings = vision_encoder(**inputs).last_hidden_state |
|
|
|
# Now you can use visual_embeddings for downstream tasks |
|
``` |
|
|
|
## Capabilities |
|
- High-quality visual feature extraction |
|
- Support for various image sizes |
|
- Robust representation learning |
|
- Compatible with multiple vision downstream tasks |
|
|
|
## Limitations |
|
- Designed specifically for feature extraction |
|
- Performance may vary depending on the specific downstream task |
|
- Requires careful preprocessing and task-specific fine-tuning |
