[PyPSA-Eur] Error in rule determine_availability_matrix_MD_UA

[gktho...@gmail.com]

Dear group,

When I run the newest pypsa-eur version with UA added as a country, the rule determine_availability_matrix_MD_UA results in the error I posted below. Does anyone have an idea what could be the issue? The environment I used is the one from the latest clone.

Best,

Georg
