Re: [matplotlib-devel] basemap installation problem with mpl master

[Jeff Whitaker]

Damon McDougall July 6, 2013 9:32 AM If I do a clean install of mpl master, and then of basemap, basemap lands in dist-packages/mpl_toolkits, as it always has.  But now it is not found--I can't import it.  It seems that now the *real* mpl_toolkits is cleverly hidden inside an egg directory with a monstrous name, leaving basemap orphaned in a directory with no __init__.py.  As a workaround I can symlink it into the egg location.  I suspect the real solution will require basemap to use setuptools, correct?  I don't know how to do this, so I hope someone who does will submit a PR. Actually, using the new setuptools isn't adequate, I just tried it locally on my machine and it still doesn't install itself into the matplotlib egg. I think the proper solution here is to add basemap as an optional dependency to matplotlib and have the user set a flag (off by default) to pull basemap if it's desired Does that sound like a reasonable solution? What if a user decides later that he/she wants to install basemap?  Then they would have to reinstall matplotlib?  That doesn't sound reasonable to me.  How about having matplotlib install a symlink to the egg location? Why the change to using setuptools by default in the first place? -Jeff P.S.  Note that the other mpl_toolkits are installed into the correct place because they are shipped with matplotlib and installed at the same time.  We could ship basemap with matplotlib too but it's a rather large download.
