Waking up early, going on a walk, making breakfast, and then spending two hours meditating on how much I wish someone would write some good, differentiable, richly featured wavelet libraries in python.

I’m tinkering with something where shearlets are very clearly The Right Tool For The Job. There is one pytorch library implementing them in what looks like a good way. Its last commit was 3 years ago and it’s not on PyPI; turns out you have to compile it locally against the CUDA SDK. Using it would instantly make my project unportable. I’m not complaining about the author of the library – if anything, I’m grateful to them. But I’m certainly complaining about the situation.
