Hello Kha to my understanding you should still be able to capture the logs when using RayTaskRunner Are you able to reproduce this example The article also mentions an issue that a user had using RayTaskRunner and that it freezes when a large number of tasks are run maybe that is similar to what you are experiencing here How many tasks are you executing If the problem persists I d also recommend creating a and sharing a simplified version of your code here for troubleshooting

Also quick note from the bottom of the article Note to anyone using `DaskTaskRunner` or `RayTaskRunner` from prefect version `2 0b8` onwards those task runners were moved to the respective Prefect Collections for better code dependency management the core library no longer requires dask or ray as dependencies now those can be installed separately when needed The correct imports are now ```from prefect dask import DaskTaskRunner from prefect ray import RayTaskRunner```
