my problem is "ValueError: all the input array dimensions for the concatenation axis must match exactly, but along dimension 1, the array at index 0 has size 50000 and the array at index 1 has size 60000

Have you solved @MrLinNing

I met the same problems as you before, I tried to use dataset.targets instead and it just worked fine.
So my code is:

labels = np.array(dataset.targets)

Could you provide a more detailed error message? For example, which line is this error come from?

num_shards, num_imgs = 200, 250
200*250=50000 ,the multiplication of these need equal to 60,000.

Change train_labels to targets
