Hi I have a problem running my flow The problem has occurred

Question

Hi I have a problem running my flow The problem has occurred before with the `local agent` The fix for that was to run the agent from the folder of the flow How do I fix this for the docker agent when the flow is dockerized ```Failed to load and execute flow run ModuleNotFoundError No module named parameters ```

Anna Geller · Answer

The best way would be to package your dependencies into a Docker image <https discourse prefect io t when i run my flow i see an error failed to load and execute flows environment modulenotfounderror no module named users username what is happening 33 possible solutions to fix missing code dependencies 3|this thread> provides much more information

Daniel Nilsen · Answer

what do you mean by package your dependencies into a Docker image All my dependencies are in my docker image ```root flow py paramenters py```

Daniel Nilsen · Answer

I use this Dockerfile command ```COPY src flows data transformation ``` All my files are in the data transformation folder

btw When setting up the flow storage I set ` stored as script =True`

Anna Geller · Answer

Gotcha thanks for providing more info For script storage there is a couple of more things you need to do <https github com anna geller packaging prefect flows blob master flows no build docker script docker run local image py|https github com anna geller packaging prefect flows blob master flows no build docker script docker run local image py>

Also can you share the current state of your Dockerfile Based on this you may need to add a couple more steps because you are using a different base image than the one from Prefect especially with script storage With pickle storage Prefect can modify your Dockerfile before build to add things like entry point but with Script storage you would need to add those missing steps check those in the Prefect main repo there is a Dockerfile Prefect uses <https prefect community slack com archives CL09KU1K7 p1646235910252089 thread ts=1646233144 405739 amp cid=CL09KU1K7|https prefect community slack com archives CL09KU1K7 p1646235910252089 thread ts=1646233144 405739 amp cid=CL09KU1K7>

Alternatively switch to Prefect base image and run the node stuff separately perhaps You haven t explained yet why do you need node

Daniel Nilsen · Answer

This is now my docker file ```FROM node 16 RUN apt get update RUN apt get install y python3 pip RUN pip3 install no cache upgrade pip setuptools COPY requirements txt requirements txt RUN pip3 install r requirements txt COPY src flows data transformation ``` there are several python files inside the data transformation folder I use node to run a javascript file as a subprocess so I need node js for my flow

Daniel Nilsen · Answer

When you mentioned packaging my dependencies did you mean using `setuptools`

Anna Geller · Answer

Yes I meant adding setup py So this Dockerfile won t work with script storage but it may work with pickle storage if you use the same Python and Prefect version in your local registration environment as you used in your Dockerfile

Anna Geller · Answer

For script based Docker storage you have to use PrefectHQ base image or extend your Dockerfile significantly by adding commands similar to <https github com PrefectHQ prefect blob master Dockerfile|https github com PrefectHQ prefect blob master Dockerfile>

Daniel Nilsen · Answer

mhm thinking face I ll try using the prefect docker base thank you for your help

Anna Geller · Answer

Good choice it s also more performant and faster to build than installing Python manually +1
