Hi Preston - because the code you submit to a dask cluster runs on different machines, those machines need all the same importable dependencies as your code. In this case it sounds like your code relies on importing from a file that is not available on your worker machines
The dask client has some helper methods for pushing files to the workers that you might want to check out, or you could bake the file into your docker image

02/08/2020, 4:53 PMwell, I actually have the whole app on an image and am telling the workers to use that image. still though dask-worker seems unable to find modules running in the CWD
do I have to use preload to add the current directory to the load path?

Yea just having the file on the machine isn’t sufficient - it needs to be importable; you could add that directory to your path or push the file to a known importable location

Copy code
import sys
import os.path
cwd = os.path.dirname(__file__)
sys.path.append(cwd)c
