我多次收到此錯誤。
Traceback (most recent call last):

result = loaded_model.predict(test_image)
AttributeError: 'NoneType' object has no attribute 'predict'
我想找出植物葉子的病害。

請解決我的問題
uj5u.com熱心網友回復：
問題似乎是這條線：
loaded_model = loaded_model.load_weights("modell.h5")
從load_weights() 的檔案中：
加載 TensorFlow 格式的權重檔案時，回傳與 tf.train.Checkpoint.restore 相同的狀態物件。在構建圖形時，一旦網路構建完成，恢復操作就會自動運行（在第一次呼叫從模型繼承的用戶定義類時，如果它已經構建，則立即運行）。
以 HDF5 格式加載權重時，回傳 None。
因此，看起來將行更改為 just:
loaded_model.load_weights("modell.h5")
會解決您的問題。
