你看一下你的 tensorflow 是不是 2.6 版,predict_classes 這個語法在最新版的不能用,你可以安裝比較低版的 tensorflow 看看,或參考另一種寫法。

TensorFlow 2.x 版已棄用 predict_classes方法
請將原來程式  prediction=model.predict_classes(test_feature_normalize) 改為以下兩列

#預測
# prediction=model.predict_classes(test_feature_normalize)
predict_x=model.predict(test_feature_normalize)
prediction=np.argmax(predict_x,axis=1)

您好:
我的環境是 Tensorflow 2.6.0 keras 2.6.0,看起來像您的一樣。

我將棄用的
prediction=model.predict_classes(test_feature_normalize)

改用
predict_x=model.predict(test_feature_normalize)
prediction=np.argmax(predict_x,axis=1)

替代,執行是正常的,請您再確定。

如果還是有問題,建議您 Tensorflow、Keras 全部移除後再重新安裝。
您也可以 e-mail 到文淵閣工作室  service@e-happy.com.tw
這樣會比較方便傳檔案給您。

上網 google 錯誤訊息,請參考這篇文章:
https://stackoverflow.com/questions/66178738/attributeerror-module-tensorflow-python-training-experimental-mixed-precision

內文中說 tensorflow 和 keras 版本不相容:
Because the installed tensorflow version does not match the keras version. Just uninstall keras and reinstall your own tensorflow corresponding version.

建議移除 keras 再重新安裝:
pip3 uninstall keras
pip3 install keras --upgrade


註:如果上面的操作仍不能解決,建議移除 Anaconda 後重新安裝新的環境。
