As this is a trivial cherry pick of a previously passing commit, I am not really sure what the problem is with CircleCI, but it looks like it might be running out of memory after building the documentation. FWIW, Travis CI appears to pass.

LGTM

As this is a trivial cherry pick of a previously passing commit, I am not really sure what the problem is with CircleCI.

Looks like the CircleCI problem is due to the fix 3daab8a to fetch_california_housing not having been backported in the 0.17.x branch. cc @ogrisel.

Hmm...so I tried to cherry-pick that commit ( 3daab8a ), as well, but it did not apply cleanly. As I am not really sure what is going on in that code, I don't feel comfortable resolving those merge conflicts. Would someone else who knows more about it please give it a try?

AFAIK (but I may be wrong about that), backports in maintenance branches are done directly by core contributors and not via PRs.

No clue. I think this is the first time I have done a PR for this project. So, not sure what the rules are. Though I would assume that most people appreciate having some of their work done for them. :) In any event, I just wanted to make sure this saw its way into a bugfix release as I know it was causing me problems.

This looks good to me. I will take care of fixing the documentation in 0.17.X.

Thanks @ogrisel.
