python - 导入 geopandas 时出错

Question

导入时出现以下错误

import geopandas as gpd

我已经使用 anaconda 安装了 geoPandas，但是当我尝试运行它时，它显示了上述错误。运行时

conda list

我得到了

以下运行后:

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

我得到了

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

Answer 1

问题是fiona和gdal的依赖不兼容导致的。通过 conda 卸载 geopandas。它还将卸载 fiona。做 conda uninstall geopandas;执行 conda install fiona=1.6

事先执行 conda search fiona 并查看它是否适用于您的 python 版本。如果不是，请为该版本的 python 创建新环境。(例如 create -n py35 python=3.5 anaconda)

然后pip install geopandas

最后，尝试import geopandas，看看是否仍然出现错误。
