Sklearn How to Save a Model Created From a Pipeline and GridSearchCV Using Joblib or Pickle?

Question

After identifying the best parameters using a pipeline and GridSearchCV, how do I pickle/joblib this process to re-use later?

Answer 1

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

If you want to dump your object into one file - use:

joblib.dump(grid.best_estimator_, 'filename.pkl', compress = 1)
