I have two models which runs on two different environments.  
I want it to deploy on one ray head node only.  
How can i do that.

I did not find any example with multiple environments.

Depending on what you need in your environment, Runtime Environments might fit the bill:  
[https://docs.ray.io/en/latest/ray-core/handling-dependencies.html#runtime-environments](https://docs.ray.io/en/latest/ray-core/handling-dependencies.html#runtime-environments)

You can pass this into the `ray_actor_options` field in Ray Serve: [Handling Dependencies — Ray 2.0.0](https://docs.ray.io/en/latest/serve/handling-dependencies.html)

Sorry to hear you’re running into errors, is there a simple script you can share that reproduces the issue?
