Missing dependencies for yaml

[pocketOfShells]

I installed on a fresh install of Ubuntu Server 18.04 in Azure.

PROBLEM
Upon running the ./generate_config.py I encountered the "ImportError: No module named yaml" error.

Running pip install yaml results in:

Collecting yaml
Could not find a version that satisfies the requirement yaml (from versions: )
No matching distribution found for yaml

SOLUTION
Run pip install pyyaml or if you want to install machine-wide run apt-get install python-yaml

I suggest either updating the dependencies or reflect this somewhere in the documentation.

I have updated the README.md file to include this information in #33

It's because of the python and pip versions.. If you are using pip, follow:
pip install --upgrade setuptools
pip install PyYAML==5.2

If you are using pip3, follow:
pip3 install --upgrade setuptools
pip3 install PyYAML==5.2

(PyYAML should be latest version.)
