C1_W3_Lab02: some thing wrong about the function: plt_one_addpt_onclick()

[EggXiaolu]

Describe the Error
When I was running:
addpt = plt_one_addpt_onclick(x_train, y_train, w_in, b_in, logistic=False)
the following error occurred:

AttributeError                            Traceback (most recent call last)

Expected behavior
it runs normally and outputs an interactive image.
