多线程下,两个线程交替打印0 -100,使用wait()和notify() public class ThreadTest{ private static final Object lock = new Object(); static class ThreadA extends Thread{ @Override public void run() { for (int i = 0; i < 100; i = i+2) { synchronized (lock){ lock.notify();
经典问题了,三个变量分别表示起始.结尾以及和,for循环从起始到结尾,和不断累积.代码如下: public class ForLoop { public static void main(String[] args){ int limit=100; int sum=0; for(int i=1;i<=limit;i++) { sum=sum+i; } System.out.println("sum="+sum); } } 效果如图:

1. UserWarning: Implicit dimension choice for log_softmax has been deprecated. Change the call to include dim=X as an argument. return F.log_softmax(x) 解决方法:把 F.log_softmax(x)改为F.log_softmax(x,dim=0) , 而且我发现改为F.log_softmax(x,dim=1),这个到底哪个更合理需要进一步确认.
