[tune] "metric" parameter not found

[ludc]

Hi,

When installing ray (using pip install, or pip install -U [last version]), the version of pbt.py in ray.tune.schedulers is not the same than the one in the GIT repository. For instance, I can't use PopulationBasedTraining.init with the parameters called 'metric' since it was not existing in the previous version. So it seems that the pip package contains an old version of tune.

How can I fix it ?

Ah you'll need to install master. Can you try installing with the wheel links here?

Hi, it did not work even if I install from the wheel links (I tested for python 3.6 and python 3.7)

I think the wheel links are not being routed correctly; can you try this for now? pip install -U despite the lower version:

I am using MacOS.... I tried this link : https://ray-wheels.s3-us-west-2.amazonaws.com/latest/ray-0.7.1-cp37-cp37m-macos_10_6_intel.whl

But the error is now: ERROR: ray-0.7.1-cp37-cp37m-macos_10_6_intel.whl is not a supported wheel on this platform.

Try adding x to macos?
