Course Q&A Deep Learning Specialization Convolutional Neural Networks

Well, after trying to figure it out for a few hours, I am here for help. The error I get is the following:

I did the dot product between the slice and W, I added all the values in “s” together with np.sum, and finally got Z by adding float(b).
I tried printing my results, and it seems that when this is casted: conv_single_step_test(conv_single_step)
the parameters b and W changed … could it be? Or where could my mistake be ?

Thanks!!

Hi @FrankAst , welcome to the discourse community and I hope the course is going well for you. If I read correctly, are you using the dot product for slice and W? Note that the exercise request an element wise product, maybe that might explain the assertion error you encounter.
