Python requirements and versions matching

[jennykim1016]

Hello!

We are trying to run this script on Mac (both M1 / M2 / Apply Silicon -- newest). We have just realized that:

• Apple Silicon doesn't natively support Python 3.8
• Conda does not support Python 3.6 but still supports Python 3.8, but the required package versions cannot be met. For instance, conda install -c tensorflow-gpu=2.2.0 or keras=2.3.1. would not work (with conda-forge)[1]. With python 3.8, import statements such as import tensorflow.compat.v2 as tf in /opt/anaconda3/envs/py38/lib/python3.8/site-packages/keras/src/engine/functional.py would not work as it requires lower-version tensorflow and keras, which again Conda doesn't support now.

Given this, what would be the best way to run the SynthSeg script, locally on the Macbook? Is there a plan to support this script in later Python versions (3.10, 3.11) that would be even more compatible with the newer hardware structures in the future?
