When trying to import geopandas into my jupyter notebook I get an ImportError: DLL load failed. I have already run pip install geopandas from my terminal and get "Requirement already satisfied". I have also tried pip install --upgrade pip setuptools which hasnt worked either. Here is the full error report when trying to import geopandas:

推荐答案

首先将conda通道添加到您的设置中(最后一个通道具有最高优先级).

First of all add conda channels to your settings (last channel has the highest priority).

conda config --add channels conda-forge
conda config --add channels defaults

然后尝试使用conda创建新环境.

Then try to create new environment using conda.

conda create -n test_python python=3.7 geopandas

就我而言，这是gdal的问题，尤其是conda-forge的最新版本(以前的版本效果很好).如果在测试环境中安装geopandas失败，则可以尝试安装 gdal 使用conda.

In my case it was a problem with gdal, especially with latest release on conda-forge (previous one works fine). If geopandas installation in test environment fails you can try to install this release (win64) of gdal using conda.

conda install "downloaded file path"
