Same issue as #1196, but for Ubuntu 23.04.

Install

conda create -n phy python=3.9 -y
conda activate phy
pip install phy --pre --upgrade

Error

@larsrollik

Not sure if it matters any more for you, but there are new installation instructions to install from source rather than pypi, which has helped others to ensure all packages are coordinated.

Easiest thing would be to download the environment.yaml and run:

conda env create -f environment.yml

Thank you, @zm711 ! I ended up containerizing it to avoid these spurious issues.
