Cannot compile the documentation

[JurgisR]

Trying to compile the documentation.
Created a virtual environment for Olympus, cloned the olympus repo, installed olympus.
Installed requirements at documentation, missing modules in the requirements:

• No module named 'sklearn' (installing manually)
• Sqlite databases require sqlalchemy (missing module) (installing manually)
• Plotter requires matplotlib, seaborn (installing manually)
• No module named m2r (installing manually)

Error after installing these modules:
sphinx/registry.py", line 266, in add_source_parser for filetype in parser.supported: AttributeError: 'str' object has no attribute 'supported' make: *** [Makefile:21: html] Error 2

I can confirm I have encountered the same issue. Interestingly I can compile the docs on my Mac in a conda env with python==3.7.3 and sphinx==2.3.1. I can share the whole env details if this may help.

This issue seemed to be caused by this:
sphinx-doc/sphinx#8395

I updated the master branch to use m2r2 and the docs should compile now - I managed to compile them with m2r2==0.2.7
