This repo contains a low-rank adapter for [LLaMA2-7b-chat](https://huggingface.co/meta-llama/Llama-2-7b-chat), trained on the 🔬 **molecule-oriented instructions** from the 🧪 [Mol-Instructions](https://huggingface.co/datasets/zjunlp/Mol-Instructions) dataset.


Instructions for running it can be found at https://github.com/zjunlp/Mol-Instructions.

> Please refer to our [paper](https://arxiv.org/abs/2306.08018) for more details.

  ```
  The molecule is a 3-sn-phosphatidyl-L-serine in which the phosphatidyl acyl groups at positions 1 and 2 are specified as stearoyl and arachidonoyl respectively. 
  It is functionally related to an arachidonic acid and an octadecanoic acid.

<h3> 📝 Demo</h3>

As illustrated in [our repository](https://github.com/zjunlp/Mol-Instructions/tree/main/demo), we provide an example to perform generation.

```shell
>> python generate.py \
    --CLI True \
    --protein False\
    --load_8bit \
    --base_model $BASE_MODEL_PATH \
    --lora_weights $FINETUNED_MODEL_PATH \
```

Please download [Llama-2-7b-chat](https://huggingface.co/meta-llama/Llama-2-7b-chat) to obtain the pre-training weights of LlamA-2-7b-chat, refine the `--base_model` to point towards the location where the model weights are saved.

For model fine-tuned on **molecule-oriented** instructions, set `$FINETUNED_MODEL_PATH` to `'zjunlp/llama2-molinst-molecule-7b'`.




<h3> 🚨 Limitations</h3>

The current state of the model, obtained via instruction tuning, is a preliminary demonstration. Its capacity to handle real-world, production-grade tasks remains limited.
