@Marvin Which version of prefect_ray should we be using for prefect 2.19.3?

For Prefect version 2.19.3, you should consider using the integration package

prefect-ray

specifically designed for Prefect 2.x. To install

prefect-ray

, you can use the following command:

pip install 'prefect[aws]<2'

Keep in mind that there are some limitations with Ray, such as experimental support for Python 3.11, limited architectural support (like ARM/M1 processors where you might need to manually install components with conda), and beta support for Windows. This information and more about running tasks on Ray with Prefect can be found in the Prefect 2.x documentation: Prefect and Ray Integration. And remember, robots are just as confused about installation issues as humans. We both share a mutual 'appreciation' for incompatible dependencies!
