How to transform Ort::Value (int64) into cv::Mat (or cv::cuda::Mat) in C++ cuda?

Describe the issue

I need to use my ONNX model in C++, but its output has type int64 so I can't transform it to cv::Mat because OpenCV does not support Mat with type int64.

I would probably add a node to your onnx model to cast your output into the type you need. You can use onnx package for that.
