I have installed geoPandas using anaconda however when I am trying to run it is displaying me the above error. When running

conda list

I am getting

After the runnning of the following:

conda install -c conda-forge fiona shapely pyproj rtree
conda install pandas
conda install -c conda-forge geopandas

I am getting

2): Library not loaded: @rpath/libnetcdf.11.dylib
  Referenced from: //anaconda/lib/libgdal.20.dylib
  Reason: Incompatible library version: libgdal.20.dylib requires version    

  12.0.0 or later, but libnetcdf.11.dylib provides version 11.0.0

Answer 1

The problem is caused by incompatibility of the fiona's and gdal's dependencies. Uninstall geopandas via conda. It will uninstall fiona as well. Do conda uninstall geopandas ; Do conda install fiona=1.6

Do conda search fiona before hand and see if it is available for your version of python. If not, create new environment for that version of python.(Ex. create -n py35 python=3.5 anaconda )

Then pip install geopandas

Finally, try to import geopandas and see if you still get the error.

Answer 2

I had the same issue in MacOs Mojave 10.14. I found out that the solution is to install geopandas via pip instead of using conda

pip install geopandas
