While trying out [Fatou.jl](https://crucialflow.com/Fatou.jl/), I had difficulty getting PyPlot to work on an M1 Mac. Here is the environement and steps that got things working.

## Python

I am not using Conda. I did follow directions [here](https://github.com/rybodiddly/Poetry-Pyenv-Homebrew-Numpy-TensorFlow-on-Apple-Silicon-M1) to set things up on the M1 with pyenv, followed by `brew install python` (non-Rosetta), pipx, and Poetry.

```julia-auto
gpip3 install numpy ## see .zshrc
gpip3 install matplotlib

brew install pyqt@5
## please see also .zshrc MPLBACKEND variable

```

## Julia

In the project, directory…

```julia-auto
julia > ENV["PYTHON"]="python3"

] add PyCall, PyPlot
] build PyCall, PyPlot

```

After this, all was well with PyPlot on the M1.
