我开始使用python xgboostbackage.有没有办法在每个训练时代获得训练和验证错误？我在文档中找不到一个
训练过一个简单的模型并获得输出:
[09:17:37] src/tree/updater_prune.cc:74:树修剪结束,1个根,124个额外节点,0个修剪节点,max_depth = 6
[0] eval-rmse:0.407474 train-rmse:0.346349 [09:17:37] src/tree/updater_prune.cc:74:树修剪结束,1根,116个额外节点,0个修剪节点,max_depth = 6
1 eval-rmse:0.410902 train-rmse:0.339925 [09:17:38] src/tree/updater_prune.cc:74:树修剪结束,1根,124个额外节点,0个修剪节点,max_depth = 6
[2] eval-rmse:0.413563 train-rmse:0.335941 [09:17:38] src/tree/updater_prune.cc:74:树修剪结束,1根,126个额外节点,0个修剪节点,max_depth = 6
[3] eval-rmse:0.418412 train-rmse:0.333071 [09:17:38] src/tree/updater_prune.cc:74:树修剪结束,1根,114个额外节点,0个修剪节点,max_depth = 6
但是,我需要在代码中传递这些eval-rmse和train-rmse进一步,或者至少绘制这些曲线.
