Cannot install RAY

Question

I am using Windows 10 Pro, 64-bit and running these scripts from Anaconda prompt.

I have tried both

pip install ray

and

pip3 install ray

with the same result

Collecting ray
Could not find a version that satisfies the requirement ray (from versions: 
)
No matching distribution found for ray

It would be great to find a workaround or troubleshooting this. Thanks

I checked ray documentation, they do not seem to mention windows anywhere, I start to wonder if it is compatible with windows. — cube, Feb 11 '19 at 12:29
indeed not compatible with windows. maybe there will be a ray distribution for windows soon — Red Sparrow, Jun 05 '19 at 14:22

UPDATE: Ray does support Windows in experimental capacity now!

See Windows installation instructions here:

~~Ray does not support Windows:~~

They propose to use the Windows subsystem for Linux as the most efficient workaround:

Do you have some timing comparisons between ray on windows subsystem for linux and ray on a proper linux? – Tavy Jun 27 '19 at 08:12

If you are on python 3.11 (as of 7th of Feb '23) Ray is also not available, so you need to downgrade to python 3.10 for now

You can install python 3.10 parallel to 3.11 and use the following commands to create a 3.10 environment

python3.10 -m venv venv
source ./venv/bin/activate
pip install ray
