AttributeError: module 'ray.tune' has no attribute 'report' #8991
Description
What is your question?
Ray version 0.8.5
pytorch version 1.0.1.post2
OS: Ubuntu 18
I copied the tutorial from https://docs.ray.io/en/master/tune.html#tune-index
into an empty python file tune.py
then I call python tune.py, I got the following error in the error log file
I checked separatedly, ray.tune on my machine indeed does not have a "report" method, anything I did wrong for installation? I just did as the tutorial said pip install 'ray[tune]'
