Is there a way to get the number of active and idle workers, I know the information is available in the web UI, but I couldn’t find any Python API calls.

Hmm this is a nice feature request. What are you trying to do?

Right now there’s a call for `ray.available_resources()` and `ray.cluster_resources()` that might be semi-sufficient?

I want to dynamically switch between parallel processing and single processing depending on the workload, so I can sidestep any unnecessary overhead. I think I can make do with ray.available\_resources(), thank you.
