because my model coming from refinedet net
so the return have four tensor.
when I return the result to tensor ,I meeted some problem like follow:
auto input = torch::randn({1,3,512,512});
auto flag = torch::tensor(true);
auto output = model->forward({input,flag}).toTensor();
std::cout<<output<<std::endl;
terminate called after throwing an instance of ‘c10::Error’
what(): isTensor() ASSERT FAILED at /home/qlt/LibTorch/include/ATen/core/ivalue.h:182, please report a bug to PyTorch. (toTensor at /home/qlt/LibTorch/include/ATen/core/ivalue.h:182)

how can i deal with this more tensor return question?
