Keras loading the model: TypeError: too many positional arguments

When loading the model I am getting:

TypeError: too many positional arguments

    model = load_model(model_path)

What could be wrong?

Solution

  • The legacy HD5 model format has issues.

    Switch saving the model using native .keras format.
