As you can observe from the following stacktrace, we need to also provide pillow in the environment.

Hey @Salvatore-tech, This error message says "ModuleNotFoundError: No module named 'PIL'". This indicates that the Python Imaging Library (PIL) is not installed in your environment.
Use this code to install PIL, pip install pillow
