Support for python 3.9

[16DF35DC5E7F679EF7C096F61B79B679]

The current requirements.txt specifies numpy version as 1.18.1.
However, this numpy version is only available for python versions 3.5-3.8
It would be of great help if we can start supporting python 3.9

It would be lovely if what Python versions are supported were stated at the start of the README.

Supporting Python 3.9 comes second to that.

But thanks for the info.

Got the exact same error.

For all the noobs out there:

pip uninstall python

pip install python==3.8

latest requirements have been tested in python 3.9 as well.
