Hey all, I'm trying to switch over from using python deployment to the cli so I am able to use github storage. Within my CLI I do not have all of the required dependencies to run my python file as we use a docker image and PyCharm interpreter to run the code. When running the

prefect deploy

cli command I am getting a module not found error even though the image I included contains that dependency. Is there a way to resolve this?

hey, can you explain what you mean by "image I included contains the dependency"? To run

prefect deploy

, prefect has to be installed in the environment where you're running the command

Prefect is installed, however packages such as private pypi package we have (contained in the docker image I have created and stored on aws ECR) are not in the local environment ( powershell ). When running my flows locally, I use the pycharm interpreter as the env which spins up the docker container to "run" the flows.

what module isn't found? Is it one of your private packages that's not in your CLI env?

Yes

Since I don't use my cli env to run flows or python files. I was previously using the pythonic deployment so the flows were being deployed from the docker container

I figured since the flow code is using github as storage, it shouldn't depend on the local file whenI am deploying using

prefect deploy

, only the prefect.yaml and should fail on task run instead

ah I see what you mean

Yeah it's kinda a unique situation... Is there a good location to see examples of prefect.yaml

So at the moment yes, to use the cli command you'll need to be able to load your python file successfully (which includes dependencies)

Two sort of work arounds I have for you: • you can use

client.create_deployment(...)

directly to make the request (

prefect deploy

is a big helper method around that) • you can defer your imports so your file can load and you can use the cli

Copy code

# instead of:
import my_private_package

@flow
def my_flow():
   my_private_package.func()

# do this:
@flow
def my_flow():
   import my_private_package
   my_private_package.func()

it is on the backlog to evaluate that kind of case that you just described though

Jake Kaplan

07/19/2023, 8:13 PM

so you don't need to have the code right there for a nice deployment experience

Mitch

07/19/2023, 8:13 PM

I'll give it a try. Still determining if we will use agents or workers due to our deployment method

Thanks Jake
