无法导入`fiona`（OGR包装器）和`geopandas`

Question

I installed geopandas with

conda install --channel https://conda.anaconda.org/conda-forge geopandas

which installed libgdal , libnetcdf , fiona , geopandas , kealib and a bunch of other packages.

The import gave me a conflict with libnetcdf , so I tried with:

conda install libnetcdf

The original error disappeared, but now when I try import geopandas , the fiona requirement gives an error. This is the traceback:

/Users/username/anaconda3/lib/python3.5/site-packages/fiona/collection.py in <module>()
      6 
      7 from fiona import compat

      9 from fiona.ogrext import Session, WritingSession
     10 from fiona.ogrext import (

Thanks!

I just tested in a python 3.5 conda environment and had no problem. You may find it helpful for comparison with your environment.
