🧹 Collect unnecessary or cluttering log messages

Let’s collect log messages from PyPSA-Eur that are unnecessary, overly verbose, or deprecated — especially those that clutter the output during typical workflows.

If you see any of the following, please paste them in a comment below:

• Deprecation warnings (e.g. from pandas, xarray, numpy, etc.)
• Verbose or unclear info/debug messages
• Repeated or outdated warnings

Please include:

• The full log message
• The command you ran (if relevant)

🎯 Goal: Clean up and streamline PyPSA-Eur logs for a better user experience.

Thanks for contributing!

PyPSA specific

• Importing network from PyPSA version v0.0.0 -> Bug
• Plotting warning too verbose (When combining n.plot() with other plots on a geographical axis, ensure n.plot() is called first...)

Snakemake

• The flag 'directory' used in rule all is only valid for outputs, not inputs.
