Attribute Error in Fiona when calling Pandas

See original GitHub issue

Before I installed geopandas, I used

conda install fiona shapely pyproj rtree

(I already have pandas on my machine) to satisfy all dependencies. Afterwards tried

conda install --channel conda-forge geopandas

as well as

conda install geopandas

But even with conda update -all I get

AttributeError: type object 'fiona.ogrext.FeatureBuilder' has no attribute '__reduce_cython__'

when I call geopandas in python. Did I mess up something, or does someone has this issue as well? Thanks

So you have a mixture of packages from the default channel and from conda-forge, which is not recommended (there can be binary incompatibilities between the packages), see the note here https://geopandas.readthedocs.io/en/latest/install.html#using-the-conda-forge-channel (although I have to say I find it a strange error message if that is the problem)

Since you have most of the default channel, can you try to force install fiona (and gdal, libgdal) again? (to have them from the default channel, so without -c conda-forge)?

And also, can you show the result of conda list ?

There is something wrong with the fiona package (which is being used by GeoPandas to read files)
