Py2.7 on Apple Silicon Macs

[Adamtaranto]

Note for future travellers: Python 2.7 is not available on conda-forge for ARM-64 Macs.

If you want to create an env to run Flexidot on an M-series Mac you can create a virtual OSX-64 env to install Python 2.7.

# Create a new OSX-64 env 
CONDA_SUBDIR=osx-64 conda create -n py27 python=2.7

# Activate the new env
conda activate py27

# Ensure that future package installs in this env stick to 'osx-64'
conda config --env --set subdir osx-64

Then use pip to install the last version of Biopython that was compatible with Py 2.7, and conda for the rest of the dependencies.

pip install biopython==1.76 
conda install colormap colour easydev matplotlib numpy regex
