I think I’ve discovered a bug when calling a flow from inside a flow using the

Runner

interface. My parent flow uses

pypi_base

and calls a child flow using

Runner

if the child flow also uses

pypi_base

the parent flow throws the error

Flow already has a decorator 'pypi_base'. You can specify each decorator only once.

If I remove the

Runner

call the flow works as expected.

I believe we fixed this in one of the more recent versions of metaflow. Which one are you on? It’s possible we missed a case but we definitely addressed something similar.

Thank you I updated to 2.12.8 and it works as expected.
