why it give error

[TMosh]

I’m not a mentor for this course, but the following tips might be helpful:

1. Is np.matmul() the correct function, or do you mean to use np.dot()?
2. Try sigmoid() using 1/ division instead of a negative exponent.

[Najumuddeen_Kubra]

yeah np.matmul is correct function because we multipltly matrix.

same error

[TMosh]

• Something is causing your sigmoid() function to break.

• Your code calls it with the results of np.matmul().

These could be related.

[TMosh]

Have you considered using np.exp() instead of math.exp()?

[Yagmur_Gulec]

I think you should use numpy exp since it should return an array.
