Sklearn，GridSearch:如何在执行过程中打印出进度? [英] Sklearn, gridsearch: how to print out progress during the execution?

问题描述

我正在使用sklearn中的GridSearch来优化分类器的参数.有大量数据，因此优化的整个过程需要一段时间:一天以上.我想在执行过程中观察已经尝试过的参数组合的性能.是否有可能?

I am using GridSearch from sklearn to optimize parameters of the classifier. There is a lot of data, so the whole process of optimization takes a while: more than a day. I would like to watch the performance of the already-tried combinations of parameters during the execution. Is it possible?

推荐答案

将GridSearchCV中的verbose参数设置为正数(数字越大，获得的细节越多).例如:

Set the verbose parameter in GridSearchCV to a positive number (the greater the number the more detail you will get). For instance:

GridSearchCV(clf, param_grid, cv=cv, scoring='accuracy', verbose=10)
