Hi Even, Thanks for your help!
Yes, I've tried "set USE_PATH_FOR_GDAL_PYTHON=YES" but the behaviour does not change. I believe OSGeo4W shell sets the environment variables through .bat files, and does not use system path. Am I right, Jurgen? (sorry for calling in CC) Meanwhile I've found those issue and PR that seems related: https://github.com/OSGeo/gdal/issues/3898 https://github.com/OSGeo/gdal/pull/3923 Following the steps to reproduce the problem I get the error message: C:\Users\PedroVenancio\demo.py: from osgeo import gdal (arosics) PS C:\Users\PedroVenancio> gdalinfo --versionGDAL 3.3.2, released 2021/09/01 (arosics) PS C:\Users\PedroVenancio> set USE_PATH_FOR_GDAL_PYTHON=YES (arosics) PS C:\Users\PedroVenancio> python demo.py Traceback (most recent call last): File "C:\Users\PedroVenancio\anaconda3\envs\arosics\lib\site-packages\osgeo\__init__.py", line 21, in swig_import_helper return importlib.import_module(mname) File "C:\Users\PedroVenancio\anaconda3\envs\arosics\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 657, in _load_unlocked File "<frozen importlib._bootstrap>", line 556, in module_from_spec File "<frozen importlib._bootstrap_external>", line 1166, in create_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removedImportError: DLL load failed while importing _gdal: Impossível localizar o procedimento especificado.During handling of the above exception, another exception occurred:Traceback (most recent call last): File "demo.py", line 1, in <module> from osgeo import gdal File "C:\Users\PedroVenancio\anaconda3\envs\arosics\lib\site-packages\osgeo\__init__.py", line 37, in <module> _gdal = swig_import_helper() File "C:\Users\PedroVenancio\anaconda3\envs\arosics\lib\site-packages\osgeo\__init__.py", line 33, in swig_import_helper raise ImportError(traceback_string + '\n' + msg)ImportError: Traceback (most recent call last): File "C:\Users\PedroVenancio\anaconda3\envs\arosics\lib\site-packages\osgeo\__init__.py", line 21, in swig_import_helper return importlib.import_module(mname) File "C:\Users\PedroVenancio\anaconda3\envs\arosics\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 657, in _load_unlocked File "<frozen importlib._bootstrap>", line 556, in module_from_spec File "<frozen importlib._bootstrap_external>", line 1166, in create_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removedImportError: DLL load failed while importing _gdal: Impossível localizar o procedimento especificado.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 variableto feed the PATH into os.add_dll_directory(). Are those ones really related? Thanks Even and Jurgen!
