Python and Apple Silicon

Download, install, & setup conda miniforge

After downloading the above conda setup script, make it executable, run it, and activate it

chmod +x ~/Downloads/Miniforge3-MacOSX-arm64.sh
~/Downloads/Miniforge3-MacOSX-arm64.sh
source ~/miniforge3/bin/activate

I like to use pyenv and venv so I don't use conda unless I need it specifically
```
conda init
conda config --set auto_activate_base false
```
Create a conda env
```
conda create --name <name> python=3.9
```

Tensorflow

Install tensorflow dependencies and tensorflow

conda install -c apple tensorflow-deps
pip install tensorflow-macos tensorflow-metal

Install needed packages

conda install -c conda-forge -y pandas jupyter
conda install scikit-learn

Install other packages

conda install -c conda-forge opencv
pip install matplotlib tqdm pydot scikit-image graphviz tensorflow_datasets

PyQt5

Unfortunately Qt5 is hard to get working with Apple Silicon
If you're starting a new PyQt project you're better off using PyQt6 which has support for ARM64 architectures
However if you must use PyQt5, there are various methods to do so:

With built-in Python venv (virtualenv)

If you don't like conda or don't need tensorflow use this method
Open terminal with Rosetta 2
- Go to your Applications folder and make a copy of the terminal app (may be in the Utilities subfolder)
- Right click > Get Info > Check "Open with Rosetta"
Use non-homebrew python (usually in /usr/bin/python3) to create virtual environment and activate it
```
/usr/bin/python3 -m venv env
source env/bin/activate
```

Upgrade pip and install PyQt5

pip install --upgrade pip
pip install PyQt5

With Conda

If you plan to use tensorflow in the same package on MacOS you're probably using conda as well so:

brew install pyqt5
echo 'export PATH="/opt/homebrew/Cellar/qt@5/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/opt/homebrew/Cellar/pyqt@5/<version>/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Then move the PyQt5 lib files into our conda environment

cp -r /opt/homebrew/Cellar/pyqt@5/<version>/lib/python3.9/site-packages/* ~/miniforge3/envs/<conda environment>/lib/python3.9/site-packages/
