Error

##6. 학습한 모델로 test 데이터의 범주(클래스)를 예측합니다.
y_pred = cnn_model.predict_classes(x_test)

y_pred = cnn_model.predict_classes(x_test)
y_pred = cnn_model.predict_classes(x_test)

AttributeError: 'Sequential' object has no attribute 'predict_classes'

tensorflow 버전 2.6이후로 predict_classes가 없기 때문에 발생하는 오류

해결

before)

y_pred = cnn_model.predict_classes(x_test)

after)

y_pred0 = cnn_model.predict(x_test)
y_pred = y_pred0.argmax(axis=-1)

으로 수정
