Running errors

[Cqbelt]

Hi, Professors. there are bugs when I run the code. Can you explain what they mean and how to solve the problems?

Hi @Cqbelt,

Thanks for your interest in our work.
Could you please check whether you use the same version of torchvision as mine?

Best,
Yaoyao

Thanks a lot, I'll have a look.

Hi, Professors. there bugs when I run the code. Can you explain what they mean and how to solve the problem?
when running mnemonics-training . main , 'CIFAR100' object has no attribute 'train_data'，
line 62, in train
X_train_total = np.array(self.trainset.train_data),

Hi @Liuhao-128,

Thanks for your interest in our work.

May I know the PyTorch version you are using? If you are not using the PyTorch version I mentioned in the README file, you may try to switch to that version.
