MAINT: Fix Travis and Circle - #10540

Also pushed a commit to bump tolerances in special

@larsoner Do you know if the doc issues in master mirror the ones I've observed when trying to backport in #10496? If so, let's label this for backporting to 1.3.x?

I guess I need to check the logs carefully.

LGTM since it makes the CI green again, modulo the explicit mtrand import.

I'd wait for a numpy dev to confirm they are fine with this before merging this though.

Yeah that doesn't look right. The objects are still there:

In [1]: np.__version__                                                              
Out[1]: '1.17.0'

In [2]: np.random.RandomState                                                       
Out[2]: numpy.random.mtrand.RandomState

In [3]: np.random.multinomial                                                       
Out[3]: <function RandomState.multinomial>

So I think it's a change that just affected intersphinx. CC @mattip FYI

IIRC it's still exposed in that namespace, just not documented in their API docs there anymore

ah that's why it doesn't link.

But do wonder if this is something numpy devs want to reconsider, e.g. add RandState back to their docs, with a corresponding note.

Indeed, I do think these should not have been removed from the docs, they're not even deprecated.

Well it's all still listed: https://numpy.org/devdocs/reference/random/legacy.html in the docs. It's too hard to find, and the main numpy.random docs reference mtrand explicitly which is wrong. So that should be reshuffled, and perhaps a :currentmodule: directive must be inserted in order to fix intersphinx.

For now though that won't unbreak our CI, that will take a 1.17.1 release I guess (that won't take very long, but more than a few days). So how about we merge this PR for now, fix the numpy issue, and open a scipy issue so we won't forget to revert this change before the next release?

Sounds good to me. Though I'm not sure we even need an issue, CircleCI will yell at us when the intersphinx inventory reverts with 1.17.1, if they do decide to change back.

OK, let's get this in, will open an issue in a moment. If CircleCI yells at us, great, we'll close it.

EDIT: Opened gh-10545

Thanks Eric, Ralf, all.

Ah, I do need the tolerance fix for signal here on LTS branch.
