tutorial script fails due to ModuleNotFoundError: No module named 'graph_optimizer'

tflite model compilation fails due to missing module "graph_optimizer"

any suggestions to resolve this?

I assume something is wrong in my docker image - if you have is a working image/container, perhaps you can share it on dockerhub?

For what it's worth, the basic example also fails for me with the same error.
