Hello, and thank you for your new review!

I tried to make sure that this situation didn’t happen again.

I think it’s not, plus these are medical data (anonymized but still) so
maybe we shouldn’t take the risk.

I had nervous laughter when I read that page. I managed to package
everything except for the JS widgets (I don’t know how to tackle that
and I fear it would be a lot of work for very little benefit, since
there are other visualization platforms from what I understand) and
mne-qt-browser, because it depends on MNE.

I tried to separate them, but they depend on a lot of stuff which is
not easy to organize into acyclic module imports.

I fixed that occurence, but as a general rule I’m not very confident in
my indentation taste.

I think I got it.

There were some more occurences that I neutralized.

OK.

As you see in the new series, vtk doesn’t install an egg-info, which
breaks the sanity-check phase of dependent python packages. There was
an option to let setuptools build the whole project, so the egg-info
would be installed too, but the installation plan with setup.py is
dysfunctional. So I made a terrible hack to "install" an egg-info.
There’s surely a better way to do it with python or pip, but I have no
clue as to what it would be and I can’t do much trial and error since I
have to wait for everything to build again (and vtk is quite a long
thing to compile).

Here is the v5!

I’m not used to managing such a large patch series; I hope I didn’t
make too many errors.

Best regards,

Vivien
