难以导入“`fiona`”(OGR包装器)和“`geopandas`”

Question

我安装了geopandas

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

它安装了libgdal、libnetcdf、fiona、geopandas、kealib和其他一些软件包。

该导入给了我与libnetcdf的冲突，所以我尝试了：

conda install libnetcdf

最初的错误消失了，但是现在当我尝试导入geopandas时，fiona需求会给出一个错误。这是回溯：

/Users/username/anaconda3/lib/python3.5/site-packages/fiona/collection.py in <module>()
      6 
      7 from fiona import compat
----> 8 from fiona.ogrext import Iterator, ItemsIterator, KeysIterator
      9 from fiona.ogrext import Session, WritingSession
     10 from fiona.ogrext import (

谢谢!

我刚刚在python3.5Conda环境中进行了测试，没有问题。你可能会发现这对你的环境比较有帮助。
