How to run pyflyte serialize workflows

Question

I am trying to learn flyte and how pyflyte serializes workflow to pb.

I used pyflyte init test to create an example test, then i tried to run pyflyte --verbose serialize workflows inside that test folder: and I always got:

Loading packages [] under source root /Users/<my-username>/repos/flyte-example/test
Successfully serialized 0 flyte objects

I also read it https://docs.flyte.org/projects/flytekit/en/latest/pyflyte.html#pyflyte-serialize but could not figure it out.

I want to share the pyflyte version, but there isn't flag to show version:

You needn't use pyflyte serialize if you use pyflyte run or pyflyte register command. I highly recommend you to try out our getting started guide.
