Prefect Community

Hi guys
I’m having issues when using python’s multiprocessing to run multiple flows in parallel. I know that there’s an integration with Dask for these things, but I do wonder if the error’s source is on my end or on Prefect’s end.
The error I’m getting is:
`_pickle.PicklingError: Can't pickle &lt;function name at 0x7fb2a9b37790&gt;: import of module '__prefect_loader__' failed`
I’m getting this error only when running the deployment through Prefect Cloud (Runs on Kubernetes), but not when running the flow locally.
Thanks
