Leave out the argument to the job() constructor - it is not necessary in recent versions of Modeller.

Probably what is happening is that you are running the master Python script using the 'mod9v7' script, but the slave is being run using your system Python, and the two don't match. If you use mod9v7 to run the master, you must use it for the slaves too; if you run the master using regular Python, you must also use regular Python for the slaves. But if you simply leave out the argument to job() above in Modeller 9v7, it should automatically detect which is the correct one to use.
