When posting errors, please post a minimal working example that
reproduces the error, rather than just posting the error message without
any context.

Please also try to debug the error yourself first: the error message is
complaining about NaNs. Please check your data for NaNs, e.g. in
"gen[node]" or "overall_gen".

Bare in mind that although we would never claim to right bug-free code,
90% of errors registered on this forum are because of faulty input data.
We are still grateful for error reporting to isolate the other 10% that
are to do with genuine issues in PyPSA :-).

Best,

Tom
