ArcGIS 2.8.0 GeoPandas Error - rtree problem

Question

Hello all;

In ArcGIS Pro 2.8.0 I created a clone of the default environment and  installed GeoPandas:

conda install -c conda-forge geopandas

Then in ArcGIS Pro notebook when I tried to import geopandas I got this message:

OSError: could not find or load spatialindex_c-64.dll

Based on the advice on GitHub I downgraded rtree to 0.9.3

conda install -c conda-forge rtree=0.9.3

And then I could import geopandas using ArcGIS Pro notebook:

I am wondering if anyone of you had this problem with rtree after installing geopandas and whether there is an easier fix.

I realize I'm replying to a very old thread, but for the past year we've been packaging and hosting geopandas directly on the Esri channel, ensuring there is a version which is binary compatible with the rest of Pro.

I followed @Boroushaki 's method, but doesn't work (using conda install.... in a clone env).
And what is worse is that after I modified rtree to 0.9.3 in the clone env, I can't even initialise notebook kernel.....
Do you have any suggestion? I found many people having this problem.

I've had similar issues previously when mixing channels. I avoid using conda-forge with arcgispro-py clones (esri, defaults channels) now.
