issues while building opencv-4.1.0 while dense_flow installation

[sparsh-b]

The following is the log when i ran the command: cmake -DCMAKE_BUILD_TYPE=Release -DWITH_CUDA=ON -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-4.1.0/modules/ -DWITH_TBB=ON -DBUILD_opencv_cnn_3dobj=OFF -DBUILD_opencv_dnn=OFF -DBUILD_opencv_dnn_modern=OFF -DBUILD_opencv_dnns_easily_fooled=OFF ..

Please let me know if there is any problem in general & particularly at the bolded lines...

Hi @sparsh-b sorry about the late reply. Do you have any problem when doing make?

[mikeyEcology]

I'm having trouble installing dense_flow and I have tried a number of options from the issues pages. I'm using cudatoolkit 11, so I don't know if this is the problem? When I run make -j following the instructions at INSTALL.md, I get this error:

[ 7%] Building CXX object CMakeFiles/denseflow.dir/src/dense_flow_gpu.cpp.o [ 14%] Building CXX object CMakeFiles/denseflow.dir/src/dense_warp_flow_gpu.cpp.o /home/mtabak/repos/mmaction/third_party/dense_flow/src/dense_flow_gpu.cpp:6:10: fatal error: opencv2/cudaarithm.hpp: No such file or directory 6 | #include "opencv2/cudaarithm.hpp" | ^~~~~~~~

Using: Ubuntu 20.04 Cuda compilation tools, release 11.1, V11.1.74

Does anyone have ideas? Thank you in advance.
