Python Wheel in Serverless Job in DAB

georgemichael40 — Wed, 15 Oct 2025 13:59:02 GMT

Hey,

I am trying to run a job with serverless compute, that runs python scripts.

I need the paramiko package to get my scripts to work. I managed to get it working by doing:

environments:

- environment_key: default

# Full documentation of this spec can be found at:

# https://docs.databricks.com/api/workspace/jobs/create#environments-spec

spec:

client: "1"

dependencies:

- paramiko==4.0.0

in the yaml for the job.

However, to more centralize the project config and not having to specify the package per job, I want to make use of a python wheel.

I already set up my pyproject.toml with the dependecies.

I saw other scripts online adding the following to the databricks.yml:

# A set of artifacts to build before deploying

artifacts:

type: whl

build: poetry build

path: .

Not sure if this is needed?

Also, I am not sure what to give as arguments in the environment block, because I read that this is required for the serverless job. I assume I have to fill in the dependencies in another way there now?

How would this work?

Thanks!

Hi @georgemichael40 ,

Put your whl file in the volume and then you can reference it in following way in your DAB file:

dependencies: - " /Volumes/workspace/default/my_volume/hellopkg-0.0.1-py3-none-any.whl"

Thanks for your reply.

But the documentation refers to notebooks. I am deploying a DAB that runs a serverless job to run Python scripts. Do you think that would make a difference?

Hi,

Can confirm this works! It's

dependencies:

string value of path to the wheel in the volume or workspace.

For me, workspace worked fine.

Thanks!
