Following the documentation for setting up Sphinx documentation links between packages, I have added
intersphinx_mapping = {\'python\': (\'http://docs.python.or
In case this is still an issue.. you need to leave out the slash at the end of the URL:
intersphinx_mapping = {'python': ('http://docs.python.org/2', None),
'numpy': ('http://docs.scipy.org/doc/numpy', None),
'scipy': ('http://docs.scipy.org/doc/scipy/reference', None),
'matplotlib': ('http://matplotlib.sourceforge.net', None)}
