Moved from #754

If there are no critical problems, I suggest we merge them as-is and make additional changes in separate PRs.

That sounds good. There's an issue with the GP example, I left a comment there, but I'm good w picking that up later.

The plan is no longer to have them appear in the gallery?

[fonnesbeck]

Sorry! Fixed.

Overall LGTM.

Chapter 16 and 17 mention "PyMC5". In Chapter 17 it is mentioned that pymc/pytensor uses a naive implementation log_sum_exp , is that the case?

[fonnesbeck]

It appears to be true
