懂了，谢谢老哥指点

老哥还想在问一下细节 JMM的内存屏障只是用来确保对volatile对象的读写操作不会发生重排序。 但是真正volatile关键字真正用来同步线程内存和主内存的操作是原文说的"Lock前缀的指令"这个作用吧，这个理解对么？ （顺便问一下为啥我javap 看指令操作时没有发现一个Lock开头的指令。。）

Hi,I have encountered the same problem as you. May I ask how you ultimately handled it @Bin-ze @pd162

Also, I noticed that the learning rate during training was initially 5e-6 and kept increasing. Why is this happening?

Hope to merge val loss into mmengine as soon as possible, which is a very useful feature
