Course 4/Week 1/Exercise 3 (Convolution)

Getting error message above. Based on my debugging, looks like some boundary condition since much of the convolution works. However, I am not able to see why I am getting a slice that is smaller than “requested” which then causes the error above.

Please advise if I need to share the code.
Thx.

2

One of your variables is the wrong shape.

3 
# GRADED FUNCTION: conv_forward

# mentor edit: code removed - not allowed by the Honor Code.
4

Does not fail for the built in test but fails for the external test.

5

Please take a look at the attached function and give me some pointers.

6

Posting your code breaks the course Honor Code.

When you compute a_slice_prev, check that you have the order of the indices correct.
