Train model

this is a example for Swin-transformer-celoss
cd model/Swin-transformer-celoss
CUDA_VISIBLE_DEVICES="0,1,2,3" python -m torch.distributed.launch --nproc_per_node 4 --master_port 29500 main.py   --resume <checkpoint-file> 

Eval model

this is a example for Swin-transformer-celoss
cd model/Swin-transformer-celoss
CUDA_VISIBLE_DEVICES="0" python -m torch.distributed.launch --nproc_per_node 1 --master_port 29500 main.py --eval  --resume <checkpoint-file> --test_dir <label-file>

How to run the Swin Transformer (focal loss) model on images

• Copy swin_transform_focalloss.pth to model/Swin-transformer-focalloss/
• cd model/Swin-transformer-focalloss/
• Run python run_ocsr_on_images.py --data-path ./path/of/directory/with/images
• The script runs the Swin Transformer model on all images in the given directory and saves the results in smiles_output.tsv in the same directory. Each line of the output file contains the image file name and the SMILES representation of the depicted molecule.
