In the course of finding out why a gradient calc changed in pytensor > 2.12.3 ( Something changed in `pytensor > 2.12.3` (and thus `pymc > 5.6.1`) that makes my `pytensor.gradient.grad` call get stuck - any ideas? - #32 by jonsedar ), I’ve hit a number of pain points. This one seems related but diffe…

I went and checked your different tests test1_scan Your first attempt with ravel failure has nothing to do with scan in test1_scan. Trying any at.grad(f.ravel().sum(), x.ravel()) will fail because x.ravel() is not an input to f.ravel(), even if x is an input to f. test2_scan Your second attempt te…

I’m weary of those deepcopy calls! PyMC models can’t be trivially copied like that
