## Quick Start

**Fine-tuning a CLIP model on ImageNet** is as simple as:

```bash
python vlm_toolbox/scripts/train.py \
    --dataset_name imagenet1k \
    --backbone_name vit_b_32 \
    --trainer_name clip \
    --model_type few_shot \
    --setup_type full \
    --num_epochs 100 \
    --train_batch_size 64 \
    --eval_batch_size 256 \
    --precision_dtype fp16 \
    --source huggingface \
    --main_metric_name accuracy \
    --random_state 42 \
    --device_type cuda \
    --collate_all_m2_samples False \
    --save_predictions True
```

This command uses a ViT-B/32 CLIP model from Hugging Face, automatically logs progress, and stores prediction outputs for later review.

## Usage

### Running Experiments

You can also import this toolbox as a library for more advanced or **custom** experimentation. Here’s a minimal code example illustrating how to set up a multimodal pipeline:

```python
from config.enums import (
    CLIPBackbones,
    ImageDatasets,
    Trainers,
    Sources,
    Metrics,
    Stages,
)
from pipeline.pipeline import Pipeline
from config.setup import Setup
from util.memory import flush

# 1. Define your setup
setup = Setup(
    dataset_name=ImageDatasets.IMAGENET_1K,
    backbone_name=CLIPBackbones.CLIP_VIT_B_32,
    trainer_name=Trainers.CLIP,
    model_type='few_shot',
    setup_type='full',
    num_epochs=100,
    train_batch_size=64,
    eval_batch_size=256,
    precision_dtype='fp16',
    main_metric_name=Metrics.ACCURACY,
    random_state=42,
    device_type='cuda'
)

# 2. Initialize the pipeline
pipeline = Pipeline(setup, device_type='cuda')

# 3. Run the training
pipeline.run(
    collate_all_m2_samples=False,
    save_predictions=True,
    persist=True,
)

# 4. Clean up
pipeline.tear_down()
flush()
```

> **Note**: The toolbox treats multiple data inputs as modalities: `m1` and `m2`. This modular design makes it easy to extend support for text, image, video, or other data streams.

---

### Adding New Models

One key strength of this repository is its **extensibility**. Integrating your own model is straightforward:

1. **Add Your Model to an Enum**  
   Extend `ImageBackbones` or `CLIPBackbones` in 
   [`enums.py`](vlm_toolbox/config/enums.py):
   ```python
   class ImageBackbones(BaseEnum):
       DINO_V2_GIANT = 'dino_v2_giant'
       NEW_IMAGE_MODEL = 'new_image_model'
   ```

2. **Specify the Model URL**  
   Update [`backbones.py`](vlm_toolbox/config/backbones.py):
   ```python
   class BackboneURLConfig(BaseConfig):
       config = {
           Backbones.IMAGE: {
               ImageBackbones.NEW_IMAGE_MODEL: {
                   Sources.HUGGINGFACE: 'new/image-model-url',
               },
           },
           ...
       }
   ```

3. **Train & Evaluate**  
   Reference your new model from the command line or from your Python code. Your model is now part of the VL Models Toolbox!

### Adding a New Dataset

Similar to adding new models, you can integrate additional datasets seamlessly:

1. **Extend the `ImageDatasets` Enum**  
   In [`enums.py`](vlm_toolbox/config/enums.py), add:
   ```python
   class ImageDatasets(BaseEnum):
       IMAGENET_1K = 'imagenet1k'
       FOOD101 = 'food101'
       ...
       MY_NEW_DATASET = 'my_new_dataset'
   ```

2. **Add Configuration**  
   In [`image_datasets.py`](vlm_toolbox/config/image_datasets.py), define:
   ```python
   ImageDatasetConfig.config = {
       ...
       ImageDatasets.MY_NEW_DATASET: {
           'splits': ['train', 'validation'],
           DataStatus.RAW: {
               'path': 'HuggingFaceM4/MYNEW',
               'type': StorageType.HUGGING_FACE,
           },
           DataStatus.EMBEDDING: {
               'path': '/path/to/embeddings/my_new_dataset',
               'type': StorageType.DISK,
           },
           'id_col': 'my_label_column_name',
       },
   }
   ```

3. **Validate Paths**  
   If using a local folder, ensure `StorageType.IMAGE_FOLDER` or `StorageType.DISK` is set, and that the path exists.

4. **Reference the Dataset**  
   Use `my_new_dataset` in your script or code, and you're all set. The dataset is now recognized and processed just like any other!
