Cannot run as a script from the client terminal

[yutongz2019]

I have set up a dispy cluster via 1 PC with ubuntu 18.04 and 9 RPi 3B+
The python version is 3.5.3
However, when offloading tasks from PC to PRi manually, I cannot run as a script. There is no return results.
But if I manually run line by line, it works. Even I just simply divided the script into two parts and run by hand, it still works.
I am not quite sure what happens here.
Thank you very much for your time and help!

You can run dispynode with -d option to see if there are any errors on the node. You can also check job.stderr / job.exception etc. for any errors in running job (e.g., if job.status != dispy.DispyJob.Finished).
