If you get this error:
ImportError: cannot import name 'ogr' from 'osgeo'
The most likely cause, assuming you’ve tried to install osgeo directly, is that you installed osgeo from pip and got this package: https://pypi.org/project/osgeo/#history (osgeo-0.0.0-py3-none-any.whl) — which, if you look at it, appears to just be blank files. This won’t go so well.
From what I can tell, the correct solution is to install only what’s necessary via the GDAL package. OSGEO should be included in GDAL. https://pypi.org/project/GDAL/
