AttributeError: module 'ray.tune' has no attribute 'report'

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]'

@smilesun sorry for the confusion. Here is the documentation to the latest pip release. tune.report is not available there yet (and instead should be tune.track.log) - https://docs.ray.io/en/latest/tune.html

If you want to install from master, use the latest nightly wheels: https://docs.ray.io/en/master/installation.html#latest-snapshots-nightlies

tune.report is going to replace tune.track.log in future versions of Ray.

Hi @smilesun ,

Please note that some of your examples also need to be updated after this API change from report to track.log (maybe they could be even incorporated / converted to unit tests?): https://github.com/ray-project/ray/search?q=tune.report&type=Code

I’d reopen the issue to prevent this getting forgotten:)
