Pytorch中变量的volatile属性是什么？这是一个用于在PyTorch中定义变量的示例代码.

datatensor = Variable(data, volatile=True)

我想使用std::thread像这样的库在C++中创建嵌套线程.

#include<iostream>
#include<thread>
#include<vector>
using namespace std;

void innerfunc(int inp)
{
    cout << inp << endl;
}
void outerfunc(int inp)
{
    thread * threads = new thread[inp];
    for (int i = 0; i < inp; i++)
        threads[i] = thread(innerfunc, i);
    for (int i = 0; i < inp; i++)
        threads[i].join();
    delete[] threads;
}
int main()
{
     int inp = 0;
     thread t1 = thread(outerfunc,2);
     thread t2 = thread(outerfunc,3);
     t1.join();
     t2.join();
}

我可以安全地这样做吗？我担心是否join()正常工作.
