我正在做一些與圖像字幕相關的任務，我已經加載了這樣的初始模型的權重model = InceptionV3(weights='imagenet')但我收到這樣的錯誤：AttributeError: module 'tensorflow' has no attribute 'get_default_graph'我該怎么辦？請幫忙。這是上述代碼的完整輸出。1 . -------------------------------------------------- ------------------------- AttributeError Traceback (most recent call last) in () 1 # 加載 inception v3 模型 ----> 2 模型= InceptionV3(include_top=True,weights='imagenet') 3 # InceptionV3(weights='imagenet')~/anaconda3/lib/python3.6/site-packages/keras/applications/__init__.pyin wrapper(*args, **kwargs)     26             kwargs['models'] = models     27             kwargs['utils'] = utils---> 28         return base_fun(*args, **kwargs)     29      30     return wrapper~/anaconda3/lib/python3.6/site-packages/keras/applications/inception_v3.pyin InceptionV3(*args, **kwargs)      9 @keras_modules_injection     10 def InceptionV3(*args, **kwargs):---> 11     return inception_v3.InceptionV3(*args, **kwargs)     12      13 ~/anaconda3/lib/python3.6/site-packages/keras_applications/inception_v3.pyin InceptionV3(include_top, weights, input_tensor, input_shape,pooling, classes, **kwargs)    155     156     if input_tensor is None:--> 157         img_input = layers.Input(shape=input_shape)    158     else:    159         if not backend.is_keras_tensor(input_tensor):~/anaconda3/lib/python3.6/site-packages/keras/engine/input_layer.pyin Input(shape, batch_shape, name, dtype, sparse, tensor)    176                              name=name, dtype=dtype,    177                              sparse=sparse,--> 178                              input_tensor=tensor)    179     # Return tensor including _keras_shape and _keras_history.    180     # Note that in this case train_output and test_output are the same pointer.
