Hi! i can’t find my error. Basically all my values are wrong, but I think my code is correct, please help me {moderator edit - solution code removed} dw = [[-0.00154399] [-0.00492761]] db = 0.0014555781367842193 cost = 0.0015453193941501516 AssertionError: Wrong values for grads[‘dw’]. [[-0.0…

I am getting this error, how to fix it ??? [Screenshot 2021-07-30 154126]

If you are going to use the dot product to compute the cost, it requires that you transpose the second operand. Here’s a thread which shows some examples of the techniques that can be used.

Thank you! I understand it better now.

The value you show does look like it is a 64 bit floating point value. Please print the type you are actually getting and see what it is. E.g. try adding this print statement to your code in propagate: print(f"type(db) = {type(db)}") When I run the test case for propagate with that statement in pl…

@paulinpaloalto @andres.castillo I am getting this same assertion error due to the public_tests.py checking against the wrong inputs. What do you mean by you need to “forceRefresh” to get the fix working? I have tried refreshing the page, restarting the Kernel, and typing in “forceRefresh()” and “f…

I am getting the same Assertion Error and for the type I am getting : type(db) = <class ‘numpy.ndarray’> Attaching the SS of my code {moderator edit - solution code removed}

I tried using np.float64 too , but it doesn’t change the type. I also tried using np.dot() I can’t figure out where the error is occuring

Your cost calculation is wrong. You are dotting a 1 x m array with a scalar, which will give you a 1 x m array as the output if I am reading the code correctly. Also db should be a scalar. You need an np.sum there.

@paulinpaloalto , could you tell how can I get the newer version of this notebook , this problem has wasted a lot of my time and I am not sure how this would be configured please respond as soon as possible

There is a topic on the FAQ Thread that explains how to get a clean copy of the notebook and the associated files.
