Hey @Alejandro A, did you mean Prefect or Preset? For local agent, it uses the environment it was spun out of. For Docker and Kubernetes, it uses the container.

10/05/2021, 5:26 PMHi @Kevin Kho, just this line I used to register my flow + project:
Copy code
$ prefect register --project "my project" --path myflow.pyAlejandro A
10/05/2021, 5:26 PMHow does prefect knows which dependencies to install?

Don’t think of it that the requirements are bundled up. It’s more of the execution environment needs to have the same requirements. If you run with a Local Agent, it does. But if you ran on a different computer with missing packages it would fail

If you use Docker, it would download the container on the execution environment as well

The default is Local execution to it just uses the environment you agent is in

You’re using an agent right?
