Hi Folks, when deploying self-hosted Prefect server on GCP, I am encountering this error:

Copy code

DEFAULT 2024-09-06T23:24:20.993197Z Warning! Failed to load collection 'prefect_gcp': ImportError: cannot import name 'SecretDict' from 'prefect.types' (/usr/local/lib/python3.10/site-packages/prefect/types/__init__.py)

I am using this Docker image:

Copy code

--image=prefecthq/prefect:2-latest

Anyone else has the same error? Any insight on fixes or workarounds?

hmm this feels like a version mismatch to me as in, you might have a 3.x version of prefect-gcp but 2.x version of prefect are you installing an unbounded prefect-gcp via EXTRA_PIP_PACKAGES or somehow else at runtime?

+1 to what nate said -- you might try repulling the latest image if this image was pulled early this morning

I have the same problem. The base image I use is

prefecthq/prefect:2.20.6-python3.9

and I explicitly install the following requirements for Prefect:

Copy code

prefect==2.20.6
prefect-docker==0.5.5
prefect-gcp==0.5.17

I've already tried changing to

prefect-gcp==0.5.8

but this returns the same error.

@Ruslan Bergenov Did you find a solution for this?

OK, I have figured this out https://prefect-community.slack.com/archives/C04DZJC94DC/p1725973734291069?thread_ts=1725959425.128269&cid=C04DZJC94DC

IMO this is difficult to understand from the docs alone. It's not explicitly explained what the required package is.

hi @Yanic Möller - glad you figured it out! i pinned a message about this in #CL09KU1K7 suggesting a a safe way to install extras, eg pip install ‘prefect[gcp]<3’ and the suggestion to use the extras is here in the docs perhaps we should update the integrations guide as well to contain this info

Thank you very much folks for your feedback. I haven’t had a chance to investigate it more yet.

@Nate RE: _are you installing an unbounded prefect-gcp via EXTRA_PIP_PACKAGES or somehow else at runtime?_ I was installing it like this, while deploying a Cloud Run worker:

Copy code

gcloud run deploy $WORKER --image=prefecthq/prefect:2-latest \
--set-env-vars
........
--args "prefect","worker","start","--install-policy","always","--with-healthcheck","-p","cloud_run_work_pool","-t","cloud-run"

I will try the suggested workarounds.

I just deleted the 2 Cloud Run services (worker and server). Then I redeployed my worker and server on GCP as Cloud Run services from scratch and the error is gone. I am assuming the dependency error may have been fixed.

Copy code

gcloud run deploy $SERVER --image=prefecthq/prefect:2-latest
…..

Copy code

gcloud run deploy $WORKER --image=prefecthq/prefect:2-latest
….
