so I've been trying to pip install ray in a conda environment. Here's the code I use:

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org -U ray

I get this error:

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

I tried this on a friend's mac, and it worked perfectly fine. Any help would be appreciated.

I suspect you have Python 3.8 and ray doesn't currently provide wheels for 3.8, only for 3.5-3.7, and no source code.

Downgrade to Python 3.7.

  • @ASimpleProgrammer Use newer version: https://pypi.org/project/ray/1.13.0/#files — any wheel you want, Python 3.6-3.10. – phd Aug 02 '22 at 15:47
  • I actually keep getting this error when installing in a docker container, and I don't know why. – A Simple Programmer Aug 02 '22 at 15:51

    @ASimpleProgrammer You should ask a separate question naming your platform (inside Docker), OS, Python version, and showing the full text of the error message copy/pasted from the terminal and formatted. Also the 1st thing to try is to upgrade `pip`. – phd Aug 02 '22 at 15:53
