I found that, I recently worked on a project where there was a Python library using pymc3, scikit-learn and pytensor that is used for time sensitive calculations. The performance wasn't very good and someone was pushing for us to spend a lot of time moving it to GPU, but as I had to point out, that means almost a total rewrite, not simply switching to the GPU enabled version(s) of those libraries, where they even exist.
