Convert h5 to tflite

[michisaak]

Hi,
Very nice work with this seld-net! I was trying to do some training and then convert the keras model to tflite but when I try that I am getting this error :
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

I guess it comes from some string that is not passed properly. Do you know what might be the problem?
