This is a feature request for supporting PEX in the runtime\_env of ray, which is similar to how conda is supported (see [issue #14524](https://github.com/ray-project/ray/issues/14524)).
For example, we can package an actor “foo” in a PEX file “my\_package.pex”:
`@ray.remote class Foo(object): ... `
And then initialize ray with the PEX environment to enable the worker to run “foo” in the PEX environment:
`ray.init(runtime_env = { "pex": "path/to/my_package.pex" });`
We have an example repo [GitHub - leozc/fp20](https://github.com/leozc/fp20) to package ray actors into PEX files and run the actor in a local ray cluster. The commands are:
build ray\_demo.pex in dist:
`./pants package ray_demo:ray_demo`
run ray workers in PEX environment:
`./dist/ray_demo/ray_demo.pex`
What we would like to have is to execute the code in a real cluster (e.g. cloud, k8s, etc.).

Hi Mingshi, I just created a feature request to track this on the Ray repo:

Let’s discuss more there, but if you’d be willing to contribute this we’d be happy to help you figure out the best approach 🙂

Thanks Edward! We’d be happy to contribute if you could help us with the right approach!
