thank you for providing such a nice class on GANs.
I found this issue while doing assignment C3W2A. I made a crop function which passed test_expanding_block_crop() but was then failing in the next part with test_expanding_block() .
I narrowed down the issue to how my code was handling cases with inputs having odd and even width and height (test_size parameter in test_expanding_block_crop() ).
I solved this anyways, but maybe there could be an extra check in test_expanding_block_crop() that checks the crop function correctly works when the input has odd/even width and height.
Not sure if I can post code here but If needed I can provide some more concrete example of my code.
