Dear Sir: I'm using Python3 and I'm trying to train the two .py files in /utils, I used: python3 train_classification.py --dataset='<dataset path>' --nepoch='<number epochs>' --dataset_type='<modelnet40 | shapenet>' instead but the system told me that train_classification.py: error: argument --nepoch: invalid int value: '<number epochs>' How can I fix this? Thank you very much! Best, cellist
