No module named 'trytond.backend.postgres'


I tried using the proteus library to automatically create and insert data to my gnuhealth installation.
The python script I wrote works perfectly fine as long as I run the script directly on the remote machine.
For automation purpose I am using ansible. I transfer my script to the remote machine and try to execute it, but I get a No module named 'trytond.backend.postgres' error.
I can not figure out where this error is comming from, since the programm is running fine otherwise.

This is the full traceback:

Your configuration is pointing to the wrong backend name. It is named postgresql.

Thank you very much!
I am honestly surprised that it worked without any problems as long as it runs on the remote machine.
