--no-wandb
--wandb-watch Watch the models gradient and parameters into wandb (can be
slow).
--sweep Run the code with sweep for HP search.Training can be done by specifying parameters in command line, for example:
python main.py --results-root ./results/tiny/ --data-root /data/dataset/torchvision --learner FD --dataset tiny --batch-size 10 --fd-loss agd --optim Adam --learning-rate 0.0005When using a configuration file, parameters specified in the .yaml cannot be overriten by command line arguments. However, other parameters like --data-root can be adapted to the users' need.
python main.py --data-root /Volumes/SSD2/data/dataset/torchvision --config config/icml24/ER,cifar10,m1000mbs64sbs10,blurry1500.yamlOutput of the command above should contain performances like this.
