Jason,<br><br>I appreciate the expertise for all of you along with this thread, I could already gather quite some useful information from here for this reason. I must mention that my programming practice in Python can be considered as zero, this is the main reason that my issues may have trivial solutions for the hardcore pythonists but not trivial to me. Apologies for this inconvenience :-)<br>
<br>Getting back to the original topic, you mention that the gdal binaries should be installed somewhere an set PATH, GDAL_DATA, PROJ_LIB and GDAL_DRIVER_PATH as a systemwide setting. This is where the problems of mine are starting. Modifying the PATH globally is a bad practice in 99% of the cases. The only case I'm aware of which may not be a problem when we make sure that only one version of such files (dll-s and executables) will ever be installed to a particular system. But this is not the case with the gdal binaries as I would expect at least a development or a stable version (and their x86/x64 variants) to coexist which should be used by the same user. The same problem may arise when we would like to install multiple versions to the site packages directory, how the versions of the files are maintained by the python runtime? In this regard I could mention something like what have been done with the .NET framework with the multiple versions of the packages installed simultaneously in the global assembly cache. The individual packages may specify the required minimum version of the referred packages loaded by the .NET runtime. Is this something that can be done with the python environment as well?<br>
<br>(As opposed to this, the dumb solution of having a starting script to open a command prompt (and setting PYTHONPATH properly) would ensure multiple versions to be used at the same time, since those settings are applyed to the cmd process solely.)<br>
