Unable to run eval.py via the provided json pre-trained model.

[ganeshjha]

Faced many challenges related to the tf and keras compatible version. After a lot of hassles, I was able to resolve the dependencies of libraries needed. Now, I am stuck at the below issue where it is asking for some marshal code. I believe this is coming from the custom objects passed into the model_from_json api call in eval.py line 140.
Please advise or let me know if there is any updated stable version of the codebase.

Using TensorFlow backend.
