sklearn的模型如何保存下来？

#保存

from sklearn.externals import joblib

joblib.dump(model, 'path/to/my_model.pkl')

#读取

model = joblib.load('path/to/my_model.pkl') 

参阅： Model persistence

也可以直接用pickle将模型保存到本地

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

读取

with open('filename.pkl', 'rb') as f:
    clf = pickle.load(f)
