Hello, I have a flyte .py file that imports a module I created from a subdir called lib and it contains another workflow that is intended as subflow.
Copy code
from lib.subwf import my_subwf
I can run the flyte flow successfully in local mode. However, it errored when running with --remote in the demo flyte cluster I started on my PC. The error msg is:
Copy code
ModuleNotFoundError: No module named 'lib'

currently, pyflyte run only uploads single script (workflow code) to s3, and won’t upload your subdir. Try to use pyflyte register, it will upload your workflow code and submodule.

Thanks @Kevin Su, I will try.
I registered the files. It still complaining about the same when I run flow with --remote. What else should I do before running the flow in --remote?
