General Python Error in org.python.core.PyException: ImportError:

Question

Dear all,

Unfortunately I have a problem when I try to run a python script. Everytime, independent of olca version and linux/windows, the modules can not be imported:

from org.openlca.core.database.derby import DerbyDatabase

returns

00:05:07 ERROR org.openlca.app.util.ErrorReporter - failed execute script

org.python.core.PyException: ImportError: No module named derby

Can anyone help or has an idea?

Hi WaltherZeug,
Are you trying to run the script from Tools → Developer tools → Python?
If yes, you won't be able to import panda. Also, I am wondering why you would need DerbyDatabase. Maybe you can explain what you are trying to do?
Regards,
François
