Using the Lambda layer with lambda expressions

[MatthiasRabald]

Not sure if this is really an issue of the library or rather a problem with the Python runtime API. I have a Lambda-layer in my original python code to normalize pixel values from 0-255 to 0.0-1.0 l = Lambda(lambda x: x / 255) and I want to have exactly the same layer now with Keras.Net. l = new Lambda("lambda x: x / 255")

This code throws an exception at runtime. Python.Runtime.PythonException: 'TypeError : unsupported callable' Is there a simple way to achieve the same like the python version?
