C5 W4 A1 Ex.1 get_angles() - assertion errors

Course Q&A Deep Learning Specialization Sequence Models

Hi,

I can’t believe I’m stuck in such simple exercise, so I must be missing some very simple.

I’m getting the assertion errors:
“Submatrices of odd and even columns must be equal”
and “Last value must be 0.0009486832980505137”

I really can’t see how this line of code angles = pos/np.power(10000,i*2/d) can’t be different from the equation given.

(I’m sorry to publish code, but in this case is something so little that I don’t really see any other way of explaining the issue. Feel free to eliminate the post if you feel is too much.)

So I’m sure I’m missing something very simple, but I really can’t see it. Can anybody realize what the issue is?

Hi Federico,

please read carefully this thread where you can find the error in your code. More students have the same error as you before so I recommend you to do a quick search in the forum to check if someone before posted the same question :wink:

Good luck and happy learning,

Rosa

did you use i = k / 2 or i = k // 2 ?

i used k//2 and k/2 both showed the same error
