ImportError: DLL load failed while importing _base: 找不到指定的程序。

采用Conda安装的环境

conda create -n raster_env python=3.10
conda activate raster_env
conda install -c conda-forge rasterio gdal

conda list gdal

# Name                     Version          Build            Channel
gdal                       3.6.2            py310he1c868a_9
libgdal                    3.6.2            he0cae08_9
 

conda list rasterio
# packages in environment at D:\CondaEnvs\NTL_extract_py10:

rasterio                   1.4.3            py310he5c4563_0

from osgeo import gdalimport rasterio

你的 GDAL Python 模块（from osgeo import gdal）加载失败，原因是找不到底层依赖的 gdalXXX.dll 文件。

在 Python ≥ 3.8 的 Windows 系统中，DLL 不再从 PATH 自动加载。

On Windows, with Python >= 3.8, DLLs are no longer imported from the PATH.

ImportError: DLL load failed while importing _gdal: 找不到指定的程序。 On Windows, with Python >= 3.8, DLLs are no longer imported from the PATH. If gdalXXX.dll is in the PATH, then set the USE_PATH_FOR_GDAL_PYTHON=YES environment variable to feed the PATH into os.add_dll_directory().

参考https://zhuanlan.zhihu.com/p/603881337

解决的办法将路径放入path里面：

在Pycharm里面导入os时，将路径加入到path，再导入rasterio

import os
os.environ["PATH"] =r"D:\CondaEnvs\NTL_extract_py10\Lib\site-packages\osgeo"
os.environ["PYTHONPATH"] = r"D:\CondaEnvs\NTL_extract_py10\Lib\site-packages\osgeo;"+os.environ["PATH"]
os.environ['USE_PATH_FOR_GDAL_PYTHON'] = 'YES'

import rasterio
