Errors for C3W3 Assignment Exercise 4 errors for confusion matrix

Course Q&A Natural Language Processing NLP with Sequence Models

I ran test for Exercise 4 evaluation part and got errors for confussion matrix:

Accuracy 0.54189453125

AttributeError Traceback (most recent call last)
Cell In[98], line 4
2 accuracy, cm = classify(Q1_test,Q2_test, y_test, 0.7, model, batch_size = 512)
3 print(“Accuracy”, accuracy.numpy())
----> 4 print(f"Confusion matrix:\n{cm.numpy()}")

AttributeError: ‘numpy.ndarray’ object has no attribute ‘numpy’

I use build in sklearn.metric.confusion_matrix(y_true, y_pred).

Any hints ?

But the comment tells you to use:

compute the confusion matrix using tf.math.confusion_matrix

Thanks gent: Yes. I use tf.math.confusion_matrix, the problem is solved.
