Hello! When I run the train.py file in the experiments directory according to your instructions, I execute the following command, python train.py --scenario simple After the training, I got the following error, please ask, what is the reason for this, how should I modify it? Looking forward to your reply Traceback (most recent call last): File "train.py", line 193, in train(arglist) File "train.py", line 182, in train rew_file_name = arglist.plots_dir + arglist.exp_name + '_rewards.pkl' TypeError: must be str, not NoneType

Hello! You can try to assign value to the parameters like this: python train.py --scenario simple --plots-dir 'plot_' --exp-name 'name'
