This repo contains the official checkpoints for *A Touch, Vision, and Language Dataset for Multimodal Alignment*. 

The tactile encoders comes in three different sizes: ViT-Tiny, ViT-Small, and ViT-Base, all of which are stored in
```bash
ckpt/tvl_enc
```

TVL-LLaMA, the generative counterparts, are stored in
```bash
ckpt/tvl_llama
```

## Inference
For zero-shot classification, we would require [OpenCLIP](https://github.com/mlfoundations/open_clip) with the following configuration:
```bash
CLIP_VISION_MODEL = "ViT-L-14"
CLIP_PRETRAIN_DATA = "datacomp_xl_s13b_b90k"
```

For TVL-LLaMA, please request access to the pre-trained LLaMA-2 from this [form](https://llama.meta.com/llama-downloads/). In particular, we use `llama-2-7b` as the base model. The weights here contains the trained [adapter](https://arxiv.org/abs/2309.03905), the tactile encoder, and the vision encoder for the ease of loading. 

For the complete info, please take a look at the [GitHub repo](https://tactile-vlm.github.io/) to see instructions on pretraining, fine-tuning, and evaluation with these models.
