You need to update geoviews I believe.

You need to update geoviews I believe.

It's a fresh build so I should have the latest geoviews ...

[aulemahal]

Ok weird, because the part here:

15:43:32  File /opt/conda/envs/birdy/lib/python3.10/site-packages/geoviews/links.py:4
15:43:32        3 from holoviews.plotting.links import Link, RectanglesTableLink as HvRectanglesTableLink
15:43:32  ----> 4 from holoviews.plotting.bokeh.callbacks import (
15:43:32        5     LinkCallback, RectanglesTableLinkCallback as HvRectanglesTableLinkCallback
15:43:32        6 )
15:43:32        7 from holoviews.core.util import dimension_sanitizer

is code from geoviews 1.9.1 or earlier. This was modified in 1.9.2 and latter in 1.10.0 .

[tlvu]

Oh geez you are right, mamba gave me geoviews 1.8.2 (1 year old version) !!!

This makes no sense !!!

[tlvu]

Fixed by forcing geoviews to latest 1.9.6.
