Please list python programming source codes to design a CNN$.(40$ points$)$

The configuration for the CNN is listed at page $195$ of your textbook as follows:

Conf $3$: C$64$ x $16$x$16,$ K$=3,$ S$=2,$ RelU, Dropout $=0\mathrm{.}2$

$C1688,K=2,S=2,$ ReLU, Dropout $=0\mathrm{.}2$

F$10,$ softmax, cross$-$entropy loss

You may only need to list source codes for Model Definition of Configuration

$($Similar to Code Snippet $7-4$ of pp$.199$ of your textbook$).(50$ points$)$
