Fix CalledProcessError

✅ Solution

The "CalledProcessError" in autogen often arises from subprocess commands failing due to missing dependencies, incorrect paths, or insufficient permissions within the execution environment, especially in virtual environments. Ensure all necessary packages are installed in the virtual environment (e.g., via `pip install -r requirements.txt`), verify the command paths are correct, and check for appropriate file permissions where the process is being executed. Using absolute paths to executables can sometimes bypass path-related issues, and explicitly setting environment variables may also resolve dependency conflicts.
