In the function my_softmax, you should calculate the value a and return it, so that you can use the function properly.
And if you have calculated the" softmax of z", just return it .
If there are still problems, I‘d like to see the content of your entire function

You should know that it's an assignment, so it's different from those labs, which can be run to finish without writing something.
Look at cell 3,there are
###START CODE HERE###

###END CODE HERE###
that means you should write something to fill the missing code
