Extension Error building docs

[LuckyMD]

So I just loaded sphinx v1.8.1 and tried to build the docs using make html, and I got the following error:

Extension error:
Could not import extension sphinx_autodoc_typehints (exception: No module named 'sphinx_autodoc_typehints')
make: *** [Makefile:20: html] Error 2

You are probably missing some sphinx packages:
pip3 install sphinx-autodoc-typehints sphinx_rtd_theme

Thanks... I just looked at the error again, and noticed the older error I had pasted on here also included an autocomplete error for when I was trying to look for sphinx-* packages ;).

It now builds, but it might be relevant for you that I'm getting two warnings though:
