Fix SubprocessCalledProcessError

✅ Solution

The "SubprocessCalledProcessError" in Ray often arises when a subprocess launched by Ray commands (like `ray job submit`) fails with a non-zero exit code, indicating an error during execution (e.g., missing dependencies or incorrect commands in the runtime environment creation). To fix this, carefully examine the command and environment setup within the problematic subprocess by inspecting the full error message's output and logs. Ensure all required dependencies are installed and commands are correctly specified, paying special attention to any environment variables needed for the subprocess to run correctly.
