Error in base_network

[Felix Delgado Elizundia]

Hello everyone

I am trying to learn to use Pypsa, but i am getting an error in the base_network rule

It happens with the tutorial.

Conda is updated and the pypsa environment to.

Ant help is much appreciated.

Regards

Felix Delgado

Dear Felix,

> C:\Users\felix\.conda\envs\pypsa-eur\lib\site-packages\pyproj\__init__.py:89: UserWarning: pyproj unable to set database path.
> _pyproj_global_context_initialize()

This seems like an issue with your Python package installation. See the
pyproj [1] website for more information.

Have you tried creating a fresh pypsa-eur conda environment?
(You might have some dependencies falsely installed; upgrading the
environment alone using conda or mamba update would in this case not help.)

I.e. try:

$ conda activate base
$ conda remove --name pypsa-eur --all
$ conda env create -f envs/environment.yaml

or if you have mamba installed:
$ mamba env create -f envs/environment.yaml


Best,
Johannes
