Issue Installing MuPeXI

[leldershaw]

I'm having issues installing MuPeXI as it seems that Python 2.7 support has depreciated such that Biopython requires Python 3.6 or later.

Commands used:
conda create --name mupexi python=2.7
conda activate mupexi
pip install biopython

Error message:
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

I would recommend creating a conda environment with python 2.7 and from there you can install Biopython Version 1.76, which was the last version to support both python 2 and 3
