Python3.6: Error when installing packages with pip install -r requirements.txt

[Daniel]

I'm using python3.6 and when I ran pip install -r requirements.txt to install all required packages the notebook did not work properly. When opening a notebook from the project I got this error:
/usr/bin/python: no module named ipykernel_launcher

Upon googling this issue I found the advice to reinstall this packages so I ran:

pip3 uninstall ipykernel_launcher
pip3 install ipykernel_launcher

This fixed that import issue, but when I proceeded to open a notebook I got this error:
ImportError: cannot import name 'generator_to_async_generator'

This did not have an easy fix on the internet, so I basically uninstalled all installed packages by running:

pip3 uninstall -r requirements.txt
and proceeded to install jupyter notebook with pip by running:

pip3 install jupyter

This seems to have fixed the issue, all notebooks I have tried so far have worked without issue. But I feel this should be added in the README or did I do something wrong?

@DanielPerezJensen thanks for reporting! I've fixed this with #241.
