PyCharm 中的光栅和 gdal DLL 加载失败

Question

I have a conda environment with rasterio installed and a whole load of other libraries, including gdal.

When I do:

import rasterio

on jupyter notebook, it loads fine and I can utilise it's methods etc..

When I do exactly the same thing on PyCharm, with the same environment and interpreter, I can the following error:

from rasterio._base import gdal_version
ImportError: DLL load failed: The specified module could not be found.

I'm struggling to understand why this is the case, as it loads fine in jupter notebook.

Answer 1

I encountered the same problem as you and has finished solving it.

First, You need to ensure that gdal version is still 2.x. If no, just remove it.

conda remove rasterio gdal -y

then reinstall gdal with specifying the installation version:

conda install rasterio gdal=2 -y

Then, you need add GDAL_DATA which containing a gcs.csv file to environment， for me in Windows:

setx /m GDAL_DATA C:\Users\Admin\AppData\Local\ESRI\conda\envs\python3\Library\share\gdal

reboot your computer, and import gdal before importing rasterio:
