Answer 1

The error shows that the code is written in Python 2. Probably the library depending on Cheetah is also written in Python 2. I suggest you to create a anaconda environment and install Python 2.7 instead.

If you insist to use Python 3, Cheetah3 has been released (https://cheetahtemplate.org/) You should update the version number of Cheetah in the requirements.txt file, say Cheetah==3.2.6. You may also need to use 2to3 to upgrade the code.
