In order to use the cuda package, the cuda toolkit from nvidia needs to be installed on the host system.
Please see https://docs.nvidia.com/cuda/index.html for more information.
Furthermore opencv must be compiled with cuda support.
For now we have included the make target install_cuda that compiles opencv with cuda. (For more details on the compilation process please see the Makefile)
Simply issue the command make install_cuda and you should be good to go.
Then finally verify that it is all working
cd $GOPATH/src/gocv.io/x/gocv
go run ./cmd/cuda/main.go
You should see something along the lines of:
gocv version: 0.19.0
cuda information:
Device 0: "GeForce MX150" 2003Mb, sm_61, Driver/Runtime ver.10.0/10.0
