parameter problem

[csc1233]

When I was using the following command for training, I encountered an error message that did not include the '--expt setup' parameter.I have checked the STR/args.py file and there is no defined expt-setup parameter inside.
cd STR
python main.py --seed 1 --resnet-type large --config configs/largescale/resnet18-cifar-str-1.yaml --threshold-list --multigpu 0 --er-sparse-method uniform --er-sparse-init 0.2 --name cifar-imp-er-uniform-0.2 --final_prune_epoch 150 --result-dir results --warmup-epochs 0 --prune-scheduler cosine --expt-setup rml --lr 0.1

When I remove the 'expt-setup' parameter from the command, I can train normally.
