Recognize InputLayer

[mnijh]

Hi congratulation for the great work!

A minor thing I realized during initial testing.
If the input layer of the model is given by

model.add(keras.models.InputLayer(input_shape=5))

instead of

model.add(Dense(8, input_dim=5, activation='relu'))

then this results in the error:

Traceback (most recent call last):
  File "convert_weights.py", line 353, in <module>
    h5_to_txt(
  File "convert_weights.py", line 183, in h5_to_txt
    info = model_config['config']['layers'][0]['config']['batch_input_shape'][1]

Thanks for pointing this out. A number of people have run into this issue with the input layers. I'll see about incorporating it in.
