Hello, over at Matplotlib we're trying to reference your docs on datetime64 objects, but it doesn't look like there is an entry in the numpy intersphinx inventory. Running the following doesn't produce any output:

python -m sphinx.ext.intersphinx 'https://docs.scipy.org/doc/numpy/objects.inv' | grep 'datetime64'

The grep can be removed to see the whole numpy intersphinx inventory. xref matplotlib/matplotlib#9802
