In C++, I want to get name of autograd function for tensor. I use this code:
void TensorPrintData(const torch::Tensor& t){
std::cout << t << std::endl;
if (const auto& g = t.grad_fn()){
//crash on gName at the end ob block - assertion failure
std::string gName = g->name();
std::cout << "Grad: " << gName << std::endl;
}
else if (t.requires_grad()){
std::cout << " > requires_grad" << std::endl;
}
}
but gName
causes crash when block ends with assertion failure in Visual Studio 2019 C++. I have Torch 1.9.0 cpu, x64, C++17.
