Description
What is the problem?
We have a great error message when workflow.init isn't called, but unfortunately it isn't called if ray.init also isn't called.
Ray version and other system information (Python version, TensorFlow version, OS):
Reproduction (REQUIRED)
import ray
from ray import workflow
@workflow.step
def foo(input_arg):
print(input_arg)
return "done"
print(foo.step("hello").run())

Please provide a short code snippet (less than 50 lines if possible) that can be copy-pasted to reproduce the issue. The snippet should have no external library dependencies (i.e., use fake or mock data / environments):
If the code snippet cannot be run by itself, the issue will be closed with "needs-repro-script".
- I have verified my script runs in a cl 6CD1 ean environment and reproduces the issue.
- I have verified the issue also occurs with the latest wheels.
