There seems to be something wrong with your install of either Sphinx or
numpydoc. If it's missing completely, the traceback says:

  Could not import extension numpydoc (exception: No module named
'numpydoc')

rather than complaining about "Directive". Possibly a mixup with versions?
Also note that you're saying that you see numpydoc in the sphinx directory
- did you mean in site-packages instead? That's where it should be:

In [1]: import numpydoc

In [2]: numpydoc.__file__
Out[2]:
'/home/rgommers/anaconda3/lib/python3.6/site-packages/numpydoc/__init__.py'
