Hi @Baldur,
There is no inherent limitation of installing python libraries on a photon cluster. I see that you have selected DBR 13.3. Can you provide a little more on the cluster configuration, namely is it single user or shared access? And is your workspace configured to use Unity Catalog (might become relevant, not sure)? I just ran:
%pip install geopandas fsspec
with no issue on a single user (vs shared access) photon dbr cluster in a workspace with Unity Catalog. Can you attempt again with a single user + photon dbr cluster? If you say that is what you have already tried, then I think you would want to dig in further on any restrictions your company is placing on the environment (beyond Databricks defaults).
