Flyte enables production-grade orchestration for machine learning workflows and data processing created to accelerate local workflows to production.

Flyte

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.
```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:
```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.

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?
