As illustrated in our repository, we provide an example to perform generation.

>> 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 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.
