Prefect Community

Hi, I am returning multiple values from a task and using task decorator with nout option(@task(nout=2)) but I am getting TypeError: __init__() got an unexpected keyword argument 'nout'. Am I doing anything wrong?

Ah, you'll need to upgrade. That feature was added in 0.13.17, but the latest release is 0.14.6. I recommend upgrading to the latest version.

When I install pip install prefect, I get all requirements are satisifed

You need to tell pip/conda that you want to upgrade, otherwise they see that the package is already installed and leave everything as is.

Ah makes sense. Thank you for the quick resposne
