Hi You can just make sure your module is installed in the environment where you run your dask worker

Zanie · Answer

Otherwise you can make use of Flow Storage <https docs prefect io api latest environments storage html> like our Docker storage and install your module

< Zanie> Hi Thanks for the answer If this files are only py files written by me Not a full module Storage seems me too much go over git or so Maybe do you have an example In my case i do only have some mini classes for managing objects and i would like to avoid to have all the code in one file So I only need to add these files to dask

Zanie · Answer

Storage is used no matter what the default is just to use local storage where your flow is pickled

Zanie · Answer

The issue here is that you do have a Python module with some utilities `xxx` and that is not being provided at runtime

Zanie · Answer

If you make sure that `xxx` is available on the PYTHON PATH where your flow is run then the utilities will import correctly
