Week 1 assignment 2 exercise 1 about input_size

I don’t understand where should I specify the input size in ZeroPadding2D().
I tried to write the following but it is giving the error ‘tuple’ object has no attribute ‘lower’

tfl.ZeroPadding2D(padding = 3 , data_format= (64,64,3))

Use “input_shape”, not “data_format”.

thank you! I got it now.
