Hello,

I am trying to build python files under conda env but I get the below error on RHEL 8 VM that I am running:

pip install -U [https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp38-cp38-manylinux2014\_x86\_64.whl](https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp38-cp38-manylinux2014_x86_64.whl)  
ERROR: ray-2.0.0.dev0-cp38-cp38-manylinux2014\_x86\_64.whl is not a supported wheel on this platform.

$ cat /etc/redhat-release  
Red Hat Enterprise Linux release 8.3 (Ootpa)

Can you please help?

Thanks

I tried running the below command, it works:

$ pip install -U [https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp37-cp37m-manylinux2014\_x86\_64.whl](https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp37-cp37m-manylinux2014_x86_64.whl)

Sorry for the confusion, thanks for helping!
