我如何保存模型 python3

Question

**我正在尝试保存模型以在 Web 应用程序中使用它，但出现此错误 **

X = []
sentences = list(review_df['text'])
for sen in sentences:
X.append(clean_text(sen))
y = review_df['Label']

y = np.array(list(map(lambda x: 1 if x=="fake" else 0, y)))

#使用循环神经网络 (LSTM) 进行文本分类

from keras.layers.recurrent import LSTM
model = Sequential()
embedding_layer = Embedding(vocab_size, 100, weights=[embedding_matrix], input_length=maxlen , 
trainable=False)
model.add(embedding_layer)
model.add(LSTM(128))

model.add(Dense(1, activation='sigmoid'))
model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['acc'])
print(model.summary())

#训练模型

history = model.fit(X_train, y_train, batch_size=128, epochs=6, verbose=1, validation_split=0.2)
score = model.evaluate(X_test, y_test, verbose=1) 

#打印模型结果

print("Test Score:", score[0])
print("Test Accuracy:", score[1])

#对单个实例进行预测

instance = X[57]
print(instance)
instance = tokenizer.texts_to_sequences(instance)

flat_list = []
for sublist in instance:
for item in sublist:
flat_list.append(item)

flat_list = [flat_list]

instance = pad_sequences(flat_list, padding='post', maxlen=maxlen)
model.predict(instance)

#保存模型

import pickle
with open('model.pkl', 'wb') as f:
pickle.dump(model, f)

当我尝试保存模型时，我收到此错误：TypeError: can't pickle _thread.RLock objects Is there any idea to solve this error

Answer 1

尝试这样做：

model_json = model.to_json()
with open("my_model.json", "w") as json_file:
    json_file.write(model_json)

Answer 2

您可以通过直接节省keras模型： model.save('path/xyz.h5')建议保存H5格式和使用模式model.save()您也可以加载与格式model.load()
