Thanks for the PR !

Have you run the tests ?

[SQLMaDMan]

@mpariente Yes, ran the tests, had to do a small change
added the weights_only=False
on base_models.py:114 conf = torch.load(cached_model, map_location="cpu", weights_only=False)

Haven't tested the CI changes I made

Think I introduced a build error on docs ... might have to have a look at that...
