Please help me!!!

In my lab assignment of Week 2 - Exercise 5 - propagate, this error occurs:
Logistic_Regression_with_a_Neural_Network_mindset.ipynb (74.6 KB)

UnboundLocalError Traceback (most recent call last)
in
3 X = np.array([[1., -2., -1.], [3., 0.5, -3.2]])
4 Y = np.array([[1, 1, 0]])
----> 5 grads, cost = propagate(w, b, X, Y)
6
7 assert type(grads[“dw”]) == np.ndarray

in propagate(w, b, X, Y)
46
47 # YOUR CODE ENDS HERE
—> 48 cost = np.squeeze(np.array(cost))
49
50

UnboundLocalError: local variable ‘cost’ referenced before assignment.

I am not able to find bug. I am also attaching my jupyter lab notebook for better understanding.

Check your cost function code is in the right place or not!!!

You are not suppose to share any codes or or any notebook assignment on public post. It is against guidelines.

Remove the notebook from post.
