error: namespace "cv::optflow" has no member "createOptFlow_DIS"

I'm really sorry to bother you again. There was an error about the supersufel_fusion.cu file when I compiled. Because my computer has a 3060 graphics card, I installed CUDA11.2 and OpencV is 4.4.0. The following error appears. Since I just got into SLAM, I really don't know how to solve this problem. Look forward to it
error: function "getline" cannot be called with the given argument list
argument types are: (, std::__cxx11::string)
error: incomplete type is not allowed
error: namespace "cv::optflow" has no member "createOptFlow_DIS
error: identifier "adjacency_list_all" is undefined

Hi, no problem. I am sorry I didn't have the opportunity to check what's wrong with your other issue related to g2o yet. I am getting ready for my PhD defense and will have more time after that. I think the DIS optical flow has been moved from #include <opencv2/optflow.hpp> in OpenCV 3.x.x to #include <opencv2/video/tracking.hpp> in OpenCV 4.x.x. Maybe juste changing the header can fix your issue.

Thank you very much for your reply. I have solved the above mistakes, but I still have the following mistakes when I make, so I don't know how to solve them:

Hi! I came across the same problems you posted above.
Could you please tell me how did you correct the mistakes?
