I like to do all my data transforms in numpy. E.g. random crops of very large images/arrays is very simple and fast when using the mmap mode of np.load (no need to load entire array into memory). Who honestly likes PIL?? And anyway it’s useless outside of 2D.
Also not being able to multiply numpy types (e.g. np.log(2)) with torch tensors is a nuisance… yes, I can import math but who actually uses that instead of numpy??
There’s just so much good stuff in numpy and scipy!
