Hello ! I have an issue with the code of the backpropagation of the convolutional neural network, more precisely with the conv_backward function.

I did the code, but I tells my that it computes the wrong value of dA.

“AssertionError: Wrong values for dA”. I also have the wrong values of db and dW when I compare it.

The formulas I used in the code to compute it are the same than the ones given in the exercice.

Where do you think the problem is ?

Thank you
