How to upgrade Python packages

[sahuguet]

for instance,
the pre-installed scikit-learn is 0.14. How can install 0.15?
I have 0.15 installed on my system (OSX), but the notebook only picks 0.14.

You can try to add your custom location to the PYTHONPATH setting in the app's preferences, but it's possible that that won't work properly.

I will need to update the package but unfortunately I don't have much time to work on it right now.

I already tried.
I have 0.15 installed globally. And it is not recognized by the notebook.
I have tried to mess up with sys.path. Didn't work either.

Since notebook is launching virtualenv, is there anything I can do there?
I tried to pip install -U inside virtualenv. Maybe I just need to link 0.15.

Renaming sklearn inside IPython-Notebook.app/Contents/Resources/virtualenv/lib/python2.7/site-packages and linking to 0.15 did the trick.
ln -s /Library/Python/2.7/site-packages/sklearn .

Great to hear you found a workaround for now. I think I'll eventually build on something like anaconda instead of building all packages myself but implementing that takes time as well.

another option that seems to be working is to remove the stale package from the IPython-Notebook.app/Contents/Resources/virtualenv/lib/python2.7/site-packages .
The notebook then will use the version used by Python at the OS level.

Re packaging, the issue (in this case) is not being able to update a package because it is pre-packaged with ipython. The ideal solution would be a "update button". But having a default folder when one can put their new stuff would work as well.
