Hello, I want to reform send&recv method to adapter my net env. When I try to call nccl_use_nonblocking and get error with ‘undefined reference to `c10d::nccl_use_nonblocking()’‘’.
Codes as follow:
#include <iostream>
#include <torch/csrc/distributed/c10d/NCCLUtils.hpp>
int main()
{
auto x = c10d::nccl_use_nonblocking();
std::cout << "x: " << x << "\n";
return 0;
}
Results as follow:
