Answer 1

For Microsoft Windows 10 & Python3.6.8, I installed GDAL 2.3.3 from Unofficial Windows Binaries for Python Extension Packages, modified libgdal.py adding gdal203 in the lib_names list env\Lib\site-packages\django\contrib\gis\gdal\libgdal.py.

Finally, added osgeo and proj to the PATH, and set the GDAL_LIBRARY_PATH as below (beginning of settings.py):

os.environ['PATH'] = os.path.join(BASE_DIR, r'env\Lib\site-packages\osgeo') + ';' + os.environ['PATH']

os.environ['PROJ_LIB'] = os.path.join(BASE_DIR, r'env3\Lib\site-packages\osgeo\data\proj') + ';' + os.environ['PATH']

GDAL_LIBRARY_PATH = os.path.join(BASE_DIR, r'env\Lib\site-packages\osgeo\gdal203.dll') 

In this case, env is my Python environment.
