anaconda package missing nose dependency

[megies]

The packages on anaconda cloud are missing a dependency on nose, so it is not installed automatically and then this leads to package management raising exceptions when trying to use matplotlib.

Hope this is the right place to report this packaging issue.. otherwise please lat me know where to report.

example conda info output:

The conda packages are afaik maintained by the anaconda team and not directly by us.
However, matplotlib should only depend on nose for testing and we have deliberately removed the explicit pip dependency because users complained about it being unnecessary installed. Which error are you talking about and how do you trigger it?

[megies]

Oh.. actually looking at the full traceback the missing nose wasn't triggered from matplotlib itself but from our own package (obspy) by using load_entry_point from pkg_resources module (my bad to not notice right away).

So while it is to some extent an external problem, it might still be worthwile to think about some solution for this. (although for us it'll go away as we have nose in our own dependencies for the most recent stable versions -- but potentially other people might still get hurt by this if other packages use pkg_resources in their code)

[jenshnielsen]

Which version of matplotlib are you seeing this on. We do not have any dependency on any version of nose in version 1.5.1. If you try to run the tests it will just fail informing you to install nose
1.4.x and older used to depend on nose via install_requires (1.5.0 has nose as test_requires but we dropped that due to several issues)

Closing; I gather there is no action we need to take.
