Fix UserCodeException

in Ray

Solution

UserCodeException usually indicates an error originated within the user-provided code executed as a Ray task or actor. To resolve this, carefully examine the traceback provided with the exception, paying close attention to the line numbers and specific error messages within your task/actor's code; implement proper error handling (try-except blocks) within your Ray tasks or actors to catch and manage anticipated exceptions, preventing them from crashing the entire Ray application.
