## Deployment
1. Clone
    ```shell
    git lfs install
    git clone https://huggingface.co/liyuesen/druggpt
    ```
2. Create virtual environment
    ```shell
    conda create -n druggpt python=3.7
    conda activate druggpt
    ```
3. Download python dependencies
    ```shell
    pip install datasets transformers scipy scikit-learn
    pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu117
    conda install -c openbabel openbabel
    ```
## Example usage
Run the script with the desired arguments, such as the protein sequence, ligand prompt, number of molecules to generate, and output directory.  
- If you want to input a protein FASTA file
    ```shell
    python drug_generator.py -f bcl2.fasta -n 50
    ```
- If you want to input the amino acid sequence of the protein
    ```shell
    python drug_generator.py -p MAKQPSDVSSECDREGRQLQPAERPPQLRPGAPTSLQTEPQGNPEGNHGGEGDSCPHGSPQGPLAPPASPGPFATRSPLFIFMRRSSLLSRSSSGYFSFDTDRSPAPMSCDKSTQTPSPPCQAFNHYLSAMASMRQAEPADMRPEIWIAQELRRIGDEFNAYYARRVFLNNYQAAEDHPRMVILRLLRYIVRLVWRMH -n 50
    ```
    
- If you want to provide a prompt for the ligand  
    ```shell
    python drug_generator.py -f bcl2.fasta -l COc1ccc(cc1)C(=O) -n 50
    ```
