train命令
命令功能
使用之前已存在的调优结果在use交互界面中继续调优，或直接指定模板文件目录在use交互界面调优。
命令格式
train [-h] [-r <round>] [--algorithm <algo>] [-i <ratio>]
参数说明
参数 |
说明 |
|---|---|
-h/--help |
获取帮助信息。 |
-r/--round |
指定训练的轮次，默认为50轮。 |
--algorithm |
指定训练时的算法，默认为HPO。 |
-i/--initial-random-ratio |
指定初始随机比率，该值越大，训练时的随机轮次越多。未训练时默认值为0.5，当存在训练轮次后默认值为0，取值范围0-1。 |
使用示例
可在use界面中继续两轮的自动调优，最后的报告将和之前自动调优数据一同汇总排序显示。
train -r 2
