WEEK 2, ERROR IN EXERCISE 5 (Propagate)

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning
1

Although I get correct values for “dw” and “db” the cost is not exact.

My result is 0.157… instead of 0.159… indicated as correct. (Or -2.041… vs. -2.042… in propagate test).

I cannot figure out a reason for such a slight difference, but when I tried to do the next Optimization exercise the difference there is large.

Can you give me a hint of where to search?. Many Thanks.

Hi @Joansitges,

I see you flagged this topic as “already solved”.

In the future, there’s no need to flag the post when you have found the solution. Instead, what you can do is, post about how you fixed the issue and mark is as “solution” so that other learners coming across similar issue can benefit from your insight as well.

Happy learning,

Thanks for the information. In the future I will follow your recommendation.

What worried me was that I could not copy a screenshot of the problem. The usual way of copy and paste did not work. How can it be done?

Thanks for your help
