Ray: [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?
