Following the documentation for setting up Sphinx documentation links between packages, I have added
intersphinx_mapping = {\'python\': (\'http://docs.python.or
An additional way to know how to do cross reference is with the sphobjinv module.
You can search local or even remote inventory files (with fuzzy matching). For instance with scipy:
$ sphobjinv suggest -t 90 -u https://docs.scipy.org/doc/scipy/reference/objects.inv "signal.convolve2d"
Remote inventory found.
:py:function:`scipy.signal.convolve2d`
:std:doc:`generated/scipy.signal.convolve2d`
Note that you may need to use :py:func:
and not :py:function:
(I'd be happy to know why).
