Upgrade to PyMC3 3.6

[twiecki]

These should all be ported to work with recent pymc3 and arviz.

[AlexAndorra]

I can help with that, since I'll also work on porting the exercices and/or homeworks.
From I understood though, there is a 3.7 version coming soon? If so, shouldn't we wait for it?

[twiecki]

Yes there is, and there are actually some changes (mainly renaming varnames and vars to var_names). You can for now just use master which will look 99% like 3.7.

"Rethinking" has been updated, but BDA3 and BCM are still outdated, right?

[junpenglao]

I will do an update on BCM from pymc3 master.

[AlexAndorra]

Where are we on this? Can we close? Asking because it looks like most NBs were updated.

[aloctavodia]

BCM needs to be updated. I will do it

[aloctavodia]

I offered myself to update BCM, but I never find the time, sorry :-( Does anyone else have the time to update it?

[AlexAndorra]

Maybe I could do it, but I didn't read that book -- is that a problem? The idea is just to update the syntax to new versions of PyMC and ArviZ?

[aloctavodia]

Yes, that's the idea. Thanks for your help
