Training

python -m torch.distributed.launch --nproc_per_node=8 projects/evad/run_net.py --cfg "projects/evad/configs/config_file.yaml" DATA.PATH_TO_DATA_DIR "path/to/ava" TRAIN.CHECKPOINT_FILE_PATH "path/to/pretrain.pth" OUTPUT_DIR "path/to/output"

Validation

You can load specific checkpoint file with TEST.CHECKPOINT_FILE_PATH or autoload the last checkpoint from the output folder.

python -m torch.distributed.launch --nproc_per_node=1 projects/evad/run_net.py --cfg "projects/evad/configs/config_file.yaml" DATA.PATH_TO_DATA_DIR "path/to/ava" TRAIN.ENABLE False TEST.ENABLE True NUM_GPUS 1 OUTPUT_DIR "path/to/output"
