Question

I am not able to find flyte documentation for the resolution of this issue Could anyone share the root cause of the error and the fix

Niels Bantilan · Answer

hi < Frank Shen> can you share what you re running to get the error As < Kevin Su> mentioned you can use the command to package and register your workflow to your Flyte cluster ```pyflyte register image lt image gt lt version gt lt workflows directory gt ``` Where ` lt workflows directory gt ` is the root directory containing all of the code you want to ship with your image

Frank Shen · Answer

Sure < Niels Bantilan> The command is ```pyflyte run remote refer subworkflow in lib py parent wf a 9```

Frank Shen · Answer

In refer subworkflow in lib py file ```from lib subwf import op t1 my subwf```

Frank Shen · Answer

I run command last param flyte is the folder name ```pyflyte register image dai mlp flyte demo image 1 flyte```

Frank Shen · Answer

And I got ``` from lib subwf import op t1 my subwf ModuleNotFoundError No module named lib ```

Kevin Su · Answer

Hi < Frank Shen> could you try ```pyflyte register image dai mlp flyte demo image 1 refer subworkflow in lib py```

Frank Shen · Answer

Hi < Kevin Su> I tried and got the same error ``` from lib subwf import op t1 my subwf ModuleNotFoundError No module named lib ```

Kevin Su · Answer

It s wired mind sharing your entire folder to me upload to github or somewhere I can dig into it

Frank Shen · Answer

It s not having a git repo yet Will that be the issue

Frank Shen · Answer

Also I have flyte installed in the venv in the env folder

Kevin Su · Answer

it shouldn t need to be git repo

Frank Shen · Answer

and I have conda activated

Frank Shen · Answer

I can try deactivate conda

Frank Shen · Answer

< Kevin Su> I found the reason I have init file in the root folder I don t know why flyte doesn t like it though Do you

Frank Shen · Answer

After registering I run the command below and it failed for ModuleNotFoundError No module named lib again in the pod ```pyflyte run remote refer subworkflow in lib py parent wf a 6```

Frank Shen · Answer

Do I need to restart the demo cluster in docker first

Frank Shen · Answer

Restarting demo cluster didn t help

Kevin Su · Answer

you have to use pyflyte register and manually trigger the workflow on flyte console ```pyflyte register refer subworkflow in lib py```

Yee · Answer

< Frank Shen> the figuring out of where the base directory is is actually not trivial the tools try to rely on the existence of init files to figure out where the base folder is

Yee · Answer

of the given files it walks up the folder structure until it finds a folder that doesn t have an init file

Yee · Answer

that folder is assumed to be the root this doesn t play nice with users who have namespace packages though which is something we re working on finding a ux friendly way to address

Yee · Answer

having init files set at the right place should get things to work

Yee · Answer

pyflyte run is different story that s only works if all your code is in a single file

Yee · Answer

it was written as a quick and easy way to get started or iterate on things

Yee · Answer

eventually as your repo grows you ll want more than one file and you ll have to move to the register package patterns

Frank Shen · Answer

Thank you < Yee> for the explanations
