python - 试图将我的 CNN 模型保存在 Pickle 文件中，但出现 TypeError: can't pickle _thread._local objects

Question

尝试2 methods了两者都给出了相同的错误，请帮助我将其保存为泡菜文件，以便我以后可以使用该模型。

我希望service.exe使用该模型进行创建，请建议一种最佳方法，因为我对数据科学比较陌生

result = classifier.predict(kyc_test_image)
kyc_training_set.class_indices
if result[0][0] == 1:
    prediction = 'pan'
else:
    prediction = 'driv'

kyc_model = classifier

import pickle
modelname = 'cnn_kyc'
outfile = open(modelname,'wb')
pickle.dump(kyc_model,outfile)
outfile.close()

---

TypeError                                 Traceback (most recent call last)
<ipython-input-35-865fb4ce2e0b> in <module>
----> 1 pickle.dump(kyc_model,outfile)
      2 outfile.close()

TypeError: can't pickle _thread._local objects

第二种方法

from sklearn.externals import joblib

joblib.dump(kyc_model, 'cnn_kyc.pkl')

cnn_from_joblib = joblib.load('cnn_kyc.pkl') 

cnn_from_joblib.predict(kyc_test_image)

Answer 1

import joblib        # to save models

# For Saving
python
path_name = "../../../"    # some path


model_name = 'model_name.sav' # I think saving it to sav format maybe will help y


joblib.dump(model, path_name + model_name)

# For Loading
joblib.load(path_name + model_name)
