Hi, I have an output tensor come from my network.
void LPRNet<SpTDatum>::PostProcess(std::vector<SpTDatum>& the_datas, torch::Tensor & model_outputs)
	{
		model_outputs = model_outputs.to(torch::kCPU);//make the variable is in CPU

		for (int i = 0; i < the_datas.size(); ++i)
		{ //each batch
			for (int j = 0; j < the_datas[i]->results->size(); ++j)
			{ //each detected LP
				if (the_datas[i]->results->at(j).HaveLp)
				{
					//process the tensor data
					std::string LpLabel = "";
					int last_char = -1;
					int current_char = -1;
					for (int k = 0; k < model_outputs[the_datas[i]->results->at(j).QueueNumber].size(0); ++k)
					{
						//each character
						current_char = model_outputs[the_datas[i]->results->at(j).QueueNumber][k].item<int>();
						if ((last_char == current_char) || (mBlankIdx == current_char)) {
							last_char = current_char;
							continue;
						}
						LpLabel += mDisplayChar[current_char];//convert the index value to character value
						last_char = current_char;
					}
					the_datas[i]->results->at(j).LpLabel = LpLabel;
				}
			}
		}
		//program end here!
	}

This program works fine and is compiled in the MSVC. However when I use GCC 7.5 to build, i got this error message

What is the other options to convert c10::Scalar to int(or other data type such as double, float, etc)
best regards,
