@Marvin when is prefect officially sunsetting agents?
m
You want to know when Prefect agents are officially being retired. Are you using Prefect 2.x or 3.x?
m
@Marvin using this image prefecthq/prefect:2.14-python3.11
m
Prefect is recommending users to upgrade from agents to workers. The sunset date for agents is mentioned for March 2024. For more detailed info, you can refer to the upgrade guide. Links: - Prefect GCP Integration - Agents Documentation

@Marvin Hi, i've made no changes to infra but i am getting this error when submitting tasks :
No such command 'agent'
assuming somewhere it's using an updated version of prefect-3.0.1
m
Your issue is likely related to the migration from agents to workers in Prefect. The
prefect agent
command has been deprecated in newer versions. Instead, you should use the
prefect worker
command. Here's an example:
Copy code
bash
prefect worker start -p [work pool name]
Make sure your environment is consistent and not unintentionally using a Prefect 3.x version as it could cause such discrepancies. For more details, check out the Prefect docs on Agents and the migration instructions from agents to workers. Links: - Agents Documentation - Upgrade Guide

@Marvin reading the task logs ic it's installing prefect-3.0.1
m
It sounds like there's an inconsistency with the Prefect version being used. If task logs mention installing
prefect-3.0.1
but your setup should be using Prefect 2.x, that's likely why you're seeing the
No such command 'agent'
error. Prefect 3.x has completely removed agents in favor of workers. Here's what you can do: 1. Check Environment Configuration: Ensure all environments (e.g., containers, virtual environments) are using Prefect 2.x. 2. Pin Prefect Version: Explicitly pin the Prefect version in your environment setup files (e.g.,
requirements.txt
or Dockerfile). Example for `requirements.txt`:
Copy code
plaintext
prefect==2.14.0
Example for Dockerfile:
Copy code
Dockerfile
FROM prefecthq/prefect:2.14-python3.11
Resolve the version mismatch, and you should no longer encounter the error with
prefect agent
. ### Links - Prefect Agents Documentation - Upgrade Guide to Workers Feel free to ask if you need further assistance!
m
@Marvin what is this about? ModuleNotFoundError: No module named 'griffe.dataclasses' and why would it be absent from a prefect install
m
The error you're encountering,
ModuleNotFoundError: No module named 'griffe.dataclasses'
, is due to recent changes in the
griffe
module. This module underwent updates that resulted in breaking changes for new Prefect installs. ### Solution: - Ensure Correct Version: Prefect should pin the
griffe
version to one that's compatible. For example, versions prior to 1.0.0. ### How to Fix: 1. Modify
requirements.txt
:
Copy code
plaintext
    griffe<1.0.0
    prefect==2.14.0  # or your specific Prefect version
2. OR Use a Compatible Docker Image: Specify a compatible Prefect Docker image that doesn't pull in the latest
griffe
. ### Example Commands: If you manage dependencies using a `requirements.txt`:
Copy code
plaintext
pip install "griffe<1.0.0"
pip install "prefect==2.14.0"
### Additional Context: - Issue #14978 on GitHub - Related Issue #14975 on GitHub These changes should resolve the
griffe.dataclasses
module not found error. Let me know if you need further assistance!

@Marvin hi, i noticed that with https://github.com/PrefectHQ/prefect-aws ; that this was archived? what was it replaced with
m
The
prefect-aws
repository has been archived and its functionalities are integrated into the main Prefect repository. ### Replacement: Most likely, the AWS integration functionalities are now part of the core offerings or have been moved to a newer package or configuration model. You'll need to check the main Prefect documentation for current AWS-related setup and configurations. For any transition details and specific migration steps, refer to the Prefect AWS integration documentation or related sections in the main docs. ### Relevant Links: - Archived Issue on GitHub - Transition Details This should help you smoothly transition from the archived setup to the current supported model. If you have more specific questions, feel free to ask!

@Marvin How does EXTRA_PIP_PACKAGES run? if i were to try to re-create locally is it just pip install prefect-aws s3fs
m
The
EXTRA_PIP_PACKAGES
environment variable allows Prefect to install additional Python packages at runtime. This is specified in your deployment configuration. ### How it Works: When you set the
EXTRA_PIP_PACKAGES
environment variable in your deployment's job variables, Prefect will use it to install the specified packages when your flow runs. ### Example: In a deployment configuration, it could look something like this:
Copy code
python
if __name__ == "__main__":
    get_repo_info.deploy(
        name="my-deployment",
        work_pool_name="my-pool",
        job_variables={"env": {"EXTRA_PIP_PACKAGES": "prefect-aws s3fs"}},
        image="my-image:my-tag",
        push=False
    )
### Recreate Locally: To replicate the behavior locally, you can simply use `pip install`:
Copy code
bash
pip install prefect-aws s3fs
### Documentation Link: For more information, refer to Prefect Deployment Guide. This should help you extend your Prefect environment with the necessary dependencies. Let me know if you need further information!
m
@Marvin so pip install prefect-aws is updating my prefect version. how can i prevent this?
m
To prevent
pip install prefect-aws
from updating your Prefect version, you should pin the version of Prefect explicitly in your installation command. This can be done using pip's version specifiers. ### Example Command:
Copy code
bash
pip install prefect-aws s3fs prefect==2.14.0
This command will install
prefect-aws
and
s3fs
while ensuring
Prefect
stays at version
2.14.0
. ### Dockerfile Example: If you're using a Dockerfile, you can set it up like this:
Copy code
Dockerfile
FROM prefecthq/prefect:2.14-python3.11

# Ensure Prefect version remains 2.14.x
RUN pip install prefect-aws s3fs prefect==2.14.0
### requirements.txt Example: If you manage dependencies with a
requirements.txt
file:
Copy code
plaintext
prefect==2.14.0
prefect-aws
s3fs
Then run:
Copy code
bash
pip install -r requirements.txt
By pinning the Prefect version, you ensure other package installations don't inadvertently update it. Feel free to reach out if you have more questions!
