训练train_model.py进行图像字幕处理时出错

Question

  

提高RuntimeError（“使用模型之前，您必须先对其进行编译。”）

     

RuntimeError：您必须先编译模型，然后再使用它。

    def create_model(self, ret_model = False):
    base_model = VGG16(weights='imagenet', include_top=False, input_shape = (224, 224, 3))
    base_model.trainable=False
    image_model = Sequential()
    image_model.add(base_model)
    image_model.add(Flatten())
    image_model.add(Dense(EMBEDDING_DIM, input_dim = 4096, activation='relu'))

    image_model.add(RepeatVector(self.max_cap_len))

    lang_model = Sequential()
    lang_model.add(Embedding(self.vocab_size, 256, input_length=self.max_cap_len))
    lang_model.add(LSTM(256,return_sequences=True))
    lang_model.add(TimeDistributed(Dense(EMBEDDING_DIM)))

    model = Sequential()
    model.add(Concatenate([image_model, lang_model]))
    model.add(LSTM(1000,return_sequences=False))
    model.add(Dense(self.vocab_size))
    model.add(Activation('softmax'))
