Has anyone encountered an environment incompatibility?

I want to generate brain images from brain masks. But I don't how to prepare data. Is the test set used in the training process? I only put datas in train set. But I got a "index 0 is out of bounds for axis 0 with size 0" error.

Hi~

I have some problems with data. I use HCP datasets, the image size is 260x311x260. First, I run prepare_train_data.py to crop data, the result is :

Smallest recommended input image shape: [260 311 260]

Then, I try to run CycleGAN_3D.py to train these data, I encounter a problem:

Traceback (most recent call last):

raise ValueError("index can't contain negative values")
ValueError: index can't contain negative values

I don't understand the meaning of this error. Could you offer some suggestions for this error?

Thanks!
