Issue with the tutorial on Windows (error in rule solve_network)

[matteodefelice]

I am using the latest version of Pypsa-earth installing the environment using mamba.

Describe the Bug

When trying to solve the network I get the following error message:

INFO:pypsa.linopt:Solver command: "highs --model_file C:\Users\matte\AppData\Local\Temp\pypsa-problem-_n8dfe_z.lp --solver ipm --options_file highs_options.txt"

KeyError: 'Model   status'

The above exception was the direct cause of the following exception:

Normally, I can use my windows machine for PyPSA, is Windows supported?

Hello @matteodefelice, thanks a lot for reporting!

Do I understand properly that you using HiGHS? At the moment, HiGHS is not yet supported by the upstream, but there is a feature branch which allows to do so for power-only formulation, and a PR #1182 to use the full cross-sectoral model.
