ImportError：“read_file”函数需要“fiona”包，但未安装或未正确导入。导入 fiona 导致：

Question

尝试读取 shapefile (.shp) 并在执行以下代码行后收到ImportError 。在执行下面的代码之前，我什至 pip 安装了 GDAL、geopandas、fiona 和 shapely。

shapefile = gpd.read_file(r'C:\Users\....\Data Analysis\shapefiles\louisville.shp')

收到的错误如下，

ImportError: the 'read_file' function requires the 'fiona' package, but it is not installed or does not import correctly.
Importing fiona resulted in: DLL load failed while importing ogrext: The specified procedure could not be found.

Answer 1

显然，我使用的是以下版本的 GDAL 和 fiona 组合，这对我不起作用。

GDAL-3.3.2-cp38-cp38-win_amd64.whl

\n

菲奥娜-1.8.20-cp38-cp38-win_amd64.whl

\n

我必须卸载上述版本并安装以下版本。这解决了这个问题。

GDAL-3.2.3-cp38-cp38-win_amd64.whl

菲奥娜\xe2\x80\x911.8.19\xe2\x80\x91cp38\xe2\x80\x91cp38\xe2\x80\x91win_amd64.whl
