Created attachment 510830 [details] sphinx-err-*.log Exception occurred: File "/usr/lib64/python2.7/site-packages/numpydoc/docscrape.py", line 343, in _parse raise ValueError(msg) ValueError: The section Notes appears twice in the docstring of None in None. The full traceback has been saved in ‹attached sphinx-err-*.log›, if you want to report the issue to the developers. This is using dev-python/sphinx-1.6.3-r2. Unfortunately the error message is none too helpful. Seems we lost some context somewhere. USE=-doc serves as a workaround.
Currently this version is not in portage, guess that makes it INVALID/WONTFIX?
Thank you, Kalin. Martin, where was your ebuild from? I did not see, that we do not have the mentioned version in our tree. Do you use an overlay? Could you test this dev-python/matplotlib from the gentoo tree? It could help also to add the logs here. https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket
This was the main Gentoo repository, with ARCH=~amd64. The ebuild got removed in https://github.com/gentoo/gentoo/commit/b35eee52212164c14ae6bfb6dff4a56cae401f1b by Michał Górny. Updating to matplotlib-2.1.0-r1 required updating to sci-mathematics/sage-8.1-r2::sage-on-gentoo due to an explicit minor version dependency there. See https://github.com/cschwan/sage-on-gentoo/commit/12e1ca52181ad497cc5c05a2740e for the bump there. So yes I'm using an overlay, namely sage-on-gentoo, but no, the ebuild in question did not come from that overlay, although me using the specific version I had been using is likely due to this. Anyway, with matplotlib-2.1.0-r1[doc] I get this: Exception occurred: File "conf.py", line 19, in <module> from sphinx_gallery.sorting import ExplicitOrder ModuleNotFoundError: No module named 'sphinx_gallery' The full traceback has been saved in …, if you want to report the issue to the developers. which makes some sense since dev-python/sphinx-gallery isn't installed on my system. It would appear that the matplotlib ebuild does not reflect https://github.com/matplotlib/matplotlib/blob/v2.1.0/doc-requirements.txt in full. Do you want a separate ticket for this, or abuse this one here? Installing sphinx-gallery itself fails for bug #626878 so I can't test whether manually installing that dependency would allow me to install current matplotlib with USE=doc. Will gladly revisit once that has been resolved.

Filed bug 643840 for this in order to keep separate things separate. > Installing sphinx-gallery itself fails for bug #626878 so I can't test > whether manually installing that dependency would allow me to install > current matplotlib with USE=doc. Did work around by emerging dev-python/pytest-runner. Next I hit bug 581550 comment 10 but that appears to be a sporadic thing, since without changes the next run after that did proceed past that point. So I can confirm that matplotlib-2.1.0-r1[doc] does not encounter this specific issue, although it has several other problems. Closing as obsolete since the ebuild in question is no longer in tree.
