Alpaca_model wrong input layer

Course Q&A Deep Learning Specialization Convolutional Neural Networks

Hi, in alpaca_model, I got following error message

Test failed
Expected value

[‘InputLayer’, [(None, 160, 160, 3)], 0]

does not match the input value:

[‘InputLayer’, [(1, 160, 160, 3)], 0]

What is the first number refer to? How should I fix my code OR which section of my code should I focus on

(I could place my code here if allowed)

Thanks very much

The first number is the batch size, which should be dynamic. You never specify that when using input_shape argument to Input.
