import pypsa error

[김토피아]

Hello,

 can you please help me about following?

when import pypsa in Jupyter, there is a following error.

ImportError: cannot import name 'Coordinates' from 'xarray' (C:\Users\jskim\AppData\Local\anaconda3\Lib\site-packages\xarray\__init__.py)

Hi,

This looks like a versioning problem. Try installing an up-to-date xarray version and/or upgrade PyPSA to the latest version. You may have to try a few combinations.

Best wishes,

Hi,

I have same problem before when I installed using conda install pypsa. I recommend you to install using master branch

pip install git+https://github.com/PyPSA/PyPSA.git

Hey Alex,

can you confirm that you are using the latest pypsa version?

Best

I had the same issue when installing pyPSA 0.26. 

This was fixed by uninstalling xarray and installing the latest xarray version (2023.11.0)
