Regression test for cudaoptflow NvidiaOpticalFlow tests failing

[cudawarped]

System information (version)

• OpenCV => 4.6.0 (master latest commits as of 14/11/22)
• Operating System / Platform => Windows 11 64 Bit
• Compiler => Visual Studio 2022
• GPU => NVIDIA GeForce RTX 3070 Ti Laptop

Detailed description

The regression tests for NvidiaOpticalFlow_1_0 and NvidiaOpticalFlow_2_0 are failing.

The test for NvidiaOpticalFlow_1_0 fails because the result is different to the gs result. This could be because I am using different hardware to that which generated testdata/gpu/opticalflow/nvofGolden.flo. However the test for NvidiaOpticalFlow_2_0 is failing because the results file

testdata/gpu/opticalflow/nvofGolden_2.flo

doesn't exist?

Steps to reproduce

opencv_test_cudaoptflow.exe --gtest_filter=CUDA_OptFlow/NvidiaOpticalFlow_*_0.Regression/0

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues,
  forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files: videos, images, onnx, etc
