Fix CalledProcessError

✅ Solution

CalledProcessError in diffusers often arises from external commands (like `accelerate launch`) failing due to missing dependencies or incorrect environment setup. Ensure all required packages specified in `requirements.txt` or the script itself are installed using `pip install -r requirements.txt`, and that your environment (e.g., CUDA, system libraries) is correctly configured for the executed command. Double-check that any specified paths or commands executed within the training script are valid and accessible within the environment.
