恩恩，好的，谢了！发现只能靠试的。我训练中发现两个，理解不了的问题，一个是是我训练facenet的时候，就是一直训练，训练到loss基本不下降了，那个学习率也降到最低了。最终在val上的准备率，差不多是0.92左右。然后我拿这个模型finetun，学习率是一开始的0.01，在val上的准备率一开始有点震荡后面就是会长到0.97左右，学习率也没有降到最低。第二个是从头开始训练的时候，batchsize 90的比32的效果差10点左右，这两个我不太清楚是什么情况

@LeslieZhoa 你好，我训练的时候，在facenet上的val集，有97%多。但是用train做emmbedding，用val做验证，发现识别率才93%，这种情况应该怎么改进？

请问你测试中国人脸的时候，精度也是有0.9以上么，
