问题描述

我已经用非常大的数据集从 Python Sckit 学习模块训练了一个 RandomForestClassifier，但问题是我如何才能保存这个模型并让其他人在他们的最后应用它.谢谢！

I have trained a RandomForestClassifier from Python Sckit Learn Module with very big dataset, but question is how can I possibly save this model and let other people apply it on their end. Thank you!

推荐答案

推荐的方法是使用joblib，这样会导致文件比pickle小很多:

The recommended method is to use joblib, this will result in a much smaller file than a pickle:

from sklearn.externals import joblib
joblib.dump(clf, 'filename.pkl') 

#then your colleagues can load it

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