@Marvin is there a way to explicitly clear memory in prefect for large-running flows?

Hi! Is it possible to increase max scheduled flows in prefect? I found “max_scheduled_runs_per_flow” parameter but it seems that is is only available in prefect server not prefect.

@Marvin why am i getting this error?

from prefect.futures import wait
ImportError: cannot import name 'wait' from 'prefect.futures' (/code/.venv/lib/python3.10/site-packages/prefect/futures.py)

@Marvin how do I manually retry a task?

I've been trying to run prefect based on a custom image. I have a rather complicated image build on a separate dockerfile. I wanted to just add prefect on top of that and cobbled up the following Dockerfile

FROM [original-image]

RUN pip install prefect smbprotocol

# I keep the flow definition in the "prefect" directory
COPY prefect prefect

# The image wouldn't work without that
ENV TZ=Etc/UTC
ENV MKL_THREADING_LAYER=GNU
ENV MKL_SERVICE_FORCE_INTEL=1

# Run our flow script when the container starts
CMD ["python", "prefect/flow.py"]

So far I've been testing it in a local docker pool and all was well. I now moved to ACI and am getting entrypoint-related errors:

Error: Failed to start container zuge6yxkhm5gm, Error response: to create containerd task: failed to create shim task: failed to create container 4d9adc93761405465a82af86e363832c0e7a043a584588e48a8ef0bb55faf532: guest RPC failure: failed to create container: failed to run runc create/exec call for container 4d9adc93761405465a82af86e363832c0e7a043a584588e48a8ef0bb55faf532 with exit status 1: container_linux.go:380: starting container process caused: exec: "/opt/prefect/entrypoint.sh": permission denied: unknown

I found that the ACI pool has a default entrypoint

/opt/prefect/entrypoint.sh

, so I cleared the entrypoint field, but no dice, I'm still getting the same error. I also tried to copy the entrypoint from prefect repo into the image (this one: https://github.com/PrefectHQ/prefect/blob/main/scripts/entrypoint.sh) but that still didn't work. Any suggestions? What's the intended way to run prefect based on a custom docker image? I want to avoid altering the original image as it's pretty difficult to build already.

@Marvin how do I specify Python package dependencies (i.e., ones from PyPI as well as locally available packages in a GitHub repository)

@Marvin I keep getting this error: TypeError: ‘type’ object is not iterable My prefect version is v2.20.2 pydantic Version: 2.8.2 typer Version: 0.12.4 what is causing this?

@Marvin How do I generate an API-key for Prefect Server OSS or use the admin:password string in code?

Does anyone know how to add a

entrypoint

to

my_flow.deploy()

in Prefect 3? With a

prefect.yaml

I can give an

entrypoint

, but in the

.deploy

function I only see a

entrypoint_type

.

job_variables

and

parameters

are also possible dictionaries that I can use. Yet I can't find any documentation or see in the code what I can place in these dictionaries. Anyone has a clue on where to find this? Perhaps that's where I can add the entrypoint.

Prefect 2.0. Is there a way to upload a file in the Cloud UI as a task argument? We have been using URLs for this but as we start to expand Prefect's use in our organization it is getting challenging to make sure the prefect agent has permissions to all the S3 buckets folks might upload a file to.
