Mildnet Mobilnet possible typo.

[repocho]

Hello,

first of all thanks for the job you have this in repo!! It's great.

I wonder is this line is correct or there is a typo Original Line 127: convnet_output = GlobalAveragePooling2D()(vgg_model.output)

What I think it should be: Proposed Line 127: convnet_output = GlobalAveragePooling2D()(convnet_output)

I think convnet_output it's overwritten with the original line and therefore the previous for loop concatenation is "lost".

Thank you !!
