Environment variables

Some behavior of Ray AIR can be controlled using environment variables.

Please also see the Ray Tune environment variables.

• RAY_AIR_FULL_TRACEBACKS: If set to 1, will print full tracebacks for training functions, including internal code paths. Otherwise, abbreviated tracebacks that only show user code are printed. Defaults to 0 (disabled).

Running multiple AIR jobs concurrently on a single cluster

Running multiple AIR training or tuning jobs at the same time on a single cluster is not officially supported. We don’t test this workflow and recommend the use of multiple smaller clusters instead.

If you still want to do this, refer to the Ray Tune multi-tenancy docs for potential pitfalls.
