Issues about train "classifer_train.py" on the chexpert dataset

[liyiyue2021]

When I train the "classifer_train.py" on the chexpert dataset, it keeps printing the length of the training set, does not run to the next step, and also does not generate a saved model file.

Comment out line 117 in guided_diffusion/image_datasets.py. It will work. The print statement was inside the len function and this led to the function calling itself.
