I tried a bunch of things incl:

• Create a conda environment with supported python version
• Go to the root directory of the project, Remove .venv folder
• Activate the newly created conda environment
• Create new virtual environment using python3 -m venv .venv/

I also tried to apply the Rosetta fix as outlined here How to run the Homebrew installer under Rosetta 2 on M1 Macbook

but wasn't successfull. How can I fix this?

Answer 1

I kept running into problems with python on my M1 Mac until I went completely to Rosetta on the command line. For that, I did the following:

1. Update Rosetta: In a Terminal type:

softwareupdate --install-rosetta

2. In Finder, type ⇧⌘G and go to /Applications/Utilities. Then duplicate Terminal:

3. Rename the second Terminal to "Rosetta" (or whatever you like) and have it execute in Rosetta by checking "Open using Rosetta" in the "Get Info" dialogue:

4. Open a Rosetta Terminal and make sure it shows i386 when you issue the command arch:

4. In that terminal, install homebrew (per the homebrew homepage):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

5. Once homebrew has been installed, install miniconda using homebrew:

brew install --cask miniconda

6. Create a conda environment, for instance here a python 3.9 env named azure:

conda create -n azure python=3.9

Then activate the environment:

conda activate azure

From here on out, you have a fully functioning i386 Python system. This has resolved all problems that I had with Azure, Numpy, Pandas, etc. on my M1 Mac.
