Blocked with the alpaca_model

Course Q&A Deep Learning Specialization Convolutional Neural Networks

Hi,

I’m quite lost with the alpaca model. I guess I’m not understanding the Functional API or maybe my Python level is not good enough.
I understand what I want to do but I’m totally lost with the syntax.
For instance, data augmentation: How am I supposed to proceed?

# apply data augmentation to the inputs
inputs = data_augmentation(inputs)

Will this apply the data_augmentation to input of the model?
Then the x in the pre-code…

x = preprocess_input(None) 

# set training to False to avoid keeping track of statistics in the batch norm layer
x = base_model(None, training=None) 

# add the new Binary classification layers
# use global avg pooling to summarize the info in each channel
x = None()(x) 
# include dropout with probability of 0.2 to avoid overfitting
x = None(None)(x)

Are this x to be changed by something else by me or is it a real variable x to be later processed?

Is there open hours to support with questions like this one?

Thxs!

That line of code should be “x = data_augmentation(inputs)”.

In general, your job is to replace the “None” statements with code that implements the correct layer.

So “x = preprocess_input(None)” should replace “None” with “x”. This line of code modifies the ‘x’ data in-place by passing it through the preprocess_input() layer.

The discussion forum is open all the time, but when a mentor is available depends on where the mentors live and what hours they are available.

The mentors are all volunteers from the community, so we don’t have regular hours.

Ok, thank you. I managed to finish the assignment but mainly thanks to the guidelines. I feel very unsecure in general with TensorFlow code. I will have to go deeper on it at some point.

Thxs!
