Moving sigmoid opt to math has broken the import of pymc3

[danituckerpersonal]

Hello,

Because you recently moved the sigmoid opt to math, importing pymc3 breaks, as it looks for sigmoid in nnet still. Is this something you can fix?

Thanks!

I think it is something that can be fixed, but if you are encountering this issue you are probably using the master branch from github for pymc, which for now you should avoid. The stable 3.x version is available at v3 branch and the development of pymc3 4.0 is happening at v4 branch, I'd recommend using one of these two branches to get pymc from github.

master has some changes wrt to v3 like using Aesara instead of Theano-pymc, but it is also missing some important bugfixes that are present in v3. v4 is what really takes advantage of Aesara instead of treating it as a drop in replacement for Theano.

I know the advise is a bit tangential to the issue, but I think it's worth mentioning anyways.

The current master branch of PyMC3 is definitely a major source for this problem, but we could also add a deprecation warning and an alias for the old aesara.tensor.nnet.sigm module, just in case other code was relying on it.

Thank you all for your quick responses. I switched to v3 and got it working. Thanks! Dani From: Brandon T.
