Basemap - KeyError: 'PROJ_LIB'
I get an error when importing Basemap at HLRN Berlin
from mpl_toolkits.basemap import Basemap
KeyError: 'PROJ_LIB'
I created my env like this and the problem does only occur when using jupyter notebooks.
I noticed that the environments maintained by @willi-rath use basemap1.1.0 instead of 1.2.0 but downgrading didn't help.
The issue is also discussed here but none of the proposed solution work for me.
Any help would be appreciated.
