my bad, this is just a bug of my code, I misuse str as key not key()
Hi, I came across this issue - "stuck" too in an embed platform, is this just the computation power too slow, or this is due to some inefficiency of program?...

Forget what I said, in my case, it is due to OpenCV 4.0 reimplement of cv::FileNode data access > Persistence (storing and loading structured data to/from XML, YAML or JSON)...
