模型的dump與load

1. sklearn 參照： http://scikit-learn.org/stable/tutorial/basic/tutorial.html

from sklearn.externals import joblib

joblib.dump(clf, 'filename.pkl') 

clf = joblib.load('filename.pkl') 

以上適合所有sklearn相關的模型，如scaler模型，imputer，以及分類器模型等等。

2. xgboost 參照： http://blog.csdn.net/zc02051126/article/details/46771793

# dump model

bst.dump_model('dump.raw.txt')

# dump model with feature map

bst.dump_model('dump.raw.txt','featmap.txt')

#init model

bst = xgb.Booster({'nthread':4})

#load data

bst.load_model("model.bin")
