problem of mdl.lab3.plot_accuracy_vs_risk

[Spartanzhao]

When I running _ = mdl.lab3.plot_accuracy_vs_risk(bias_images, sorted_bias, sorted_bias_preds, "Bias vs. Accuracy")
I got these error

AttributeError Traceback (most recent call last)
Cell In[81], line 12
10 plt.xlabel("Density (Representation)")
11 plt.ylabel("Accuracy")
---> 12 _ = mdl.lab3.plot_accuracy_vs_risk(bias_images, sorted_bias, sorted_bias_preds, "Bias vs. Accuracy")

AttributeError: module 'mitdeeplearning.lab3' has no attribute 'plot_accuracy_vs_risk'

When I run:
from mitdeeplearning import lab3
dir(lab3)

I got this:

['DatasetLoader',

There is no such function called plot_accuracy_vs_risk, Could you solve this issue? I am using MAC M1, python 3.10
