Unable to install ray[tune] tune-sklearn

I'm trying to install ray[tune] tune-sklearn on my machine but keeps failing. I'm using a MacBook Pro 2019 with Big Sur Version 11.6 and Python 3.9.7 (default, Sep 16 2021, 08:50:36) [Clang 10.0.0 ] :: Anaconda, Inc. on darwin. All other packages I've tried to installed fine either using conda install or pip install except for this one. I'm struggling to find an answer online myself. I was on Python 3.8 but I removed this and installed 3.9 as I thought this was the problem. Apologies in advance, I'm new to data mining and still don't know a great deal yet.

I tried

conda install -c conda-forge -y ray-tune tune-sklearn

But got back this:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

I also tried

pip install ray[tune] tune-sklearn

But got back

zsh: no matches found: ray[tune]

Any help would be greatly appreciated, thank you.

Update:

I also tried

pip install 'ray[tune]'

And got back

ERROR: Could not find a version that satisfies the requirement ray[tune] (from versions: none)
ERROR: No matching distribution found for ray[tune]

Solution

ray[tune] is a library within the Ray distributed compute project that supports scalable hyperparameter tuning -- not a stand-alone Python package. You should be able to install ray with the proper dependencies using:

pip install "ray[tune]"

After Ray has been installed, you can reference it within your Python project using either:

import ray[tune]

from ray import tune
