Introduction

When working with distributed computing frameworks like Ray, it's essential to understand how to set up environment variables to ensure seamless integration with your models. In this article, we'll focus on setting up ray_non_carry_over_env_vars.json, a crucial file that helps you configure environment variables for your Ray applications. By the end of this guide, you'll have a solid understanding of how to set up this file and integrate it with your Ray applications.

Understanding Your Current Environment

Before we dive into setting up ray_non_carry_over_env_vars.json, let's take a look at your current environment. Run the following command to get an overview of your environment:

python collect_env.py

This command will output a list of environment variables that are currently set in your system. Take note of the variables that are relevant to your Ray application, as you'll need to configure them in the ray_non_carry_over_env_vars.json file.

How to Use VLLM

VLLM is a powerful tool for running inference on specific models. If you're new to VLLM, you might be wondering how to integrate it with your Ray application. Don't worry; we've got you covered. Here's a brief overview of how to use VLLM:

Run Inference: VLLM allows you to run inference on specific models. To do this, you'll need to configure the ray_non_carry_over_env_vars.json file to set up the necessary environment variables.
Integrate with Ray: Once you've set up the ray_non_carry_over_env_vars.json file, you can integrate VLLM with your Ray application. This will enable you to run inference on your models using the power of distributed computing.

Setting Up Ray Non-Carry Over Environment Variables

Now that we've covered the basics, let's dive into setting up ray_non_carry_over_env_vars.json. This file is used to configure environment variables that are not carried over from the parent process to the child processes in a Ray application.

Step 1: Create a New File

Create a new file named ray_non_carry_over_env_vars.json in the root directory of your project. This file will contain the environment variables that you want to configure.

Step 2: Configure Environment Variables

In the ray_non_carry_over_env_vars.json file, add the environment variables that you want to configure. For example, you might want to set the RAY_ADDRESS variable to a specific value. Here's an example of how you might configure this variable:

{
  "RAY_ADDRESS": "localhost:10001"
}

Step 3: Save the File

Save the ray_non_carry_over_env_vars.json file. This file will now be used to configure environment variables for your Ray application.

Step 4: Run Your Ray Application

Run your Ray application using the following command:

ray start --address=localhost:10001

This command will start a new Ray application with the address set to localhost:10001.

Step 5: Verify Environment Variables

Verify that the environment variables are being set correctly by running the following command:

ray get-env

This command will output a list of environment variables that are currently set in the Ray application.

Conclusion

In this article, we've covered the basics of setting up ray_non_carry_over_env_vars.json. We've discussed how to create a new file, configure environment variables, save the file, run your Ray application, and verify environment variables. By following these steps, you should now have a solid understanding of how to set up ray_non_carry_over_env_vars.json and integrate it with your Ray applications.
