I have set up GDAL v1.1.1 32bit to work with Python 2.7.18 32bit on windows 10 and everything including the bindings are working fine. Now I have found out that on this version of gdal it is not possible to use TILED=YES on GeoTIFFS as the version is too old.
I thus installed Python 3.7.8 64bit with GDAL 3.3.3. The problem is now though, that I have to set the environment variables GDAL_DATA and GDAL_DRIVER_PATH again.
Can I randomly name these variable names (e.g. GDAL_DATA_PY37) or do I have to register them somehow ?
