无法使用ipython / jupyter笔记本导入matplotlib

Question

Cannot import matplotlib with ipython/jupyter notebook through a virtual environment.

I'm able to import matplotlib just fine using the console. Having seen other SO posts I can't seem to get this set up right.

I followed this to get the separate ipython/jupyter kernel.

When I checked my locations through jupyter I get

six.__file__ : '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.pyc'

and

datutil.__file__ : '/Library/Python/2.7/site-packages/dateutil/__init__.pyc'

I am not sure these are correct. Main jupyter error below

Ok I fixed this by using the tutorial properly ( http://help.pythonanywhere.com/pages/IPythonNotebookVirtualenvs )

You need to set up a virtualenv, then make sure that you install jupyter within it. I was using the globally installed jupyter.

Then set up the new jupyter kernel (linked above) and everything should work with your virtualenv pointed to correctly
