(unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX

[hkommula]

I'm trying to install baskinmaker and I've followed these steps for a full ArcGIS installation .
After upgrading all the necessary dependencies, when testing using "test_arcgis_full" it is throwing this error. Had a quick look at the "test_full_delineation_arcgis.py" but can't seem to find the issue. Any help to fix this issue would be much appreciated.
