opencv_cudaoptflow produces no jniopencv_ximgproc in java.library.path #911

You might not have the right version of CUDA installed. Please add a dependency on cuda-redist-platform. |

Thank you for quick reply. As you said, my CUDA version (10.2.89) is different from javacpp-cuda version (10.2.76). my <project>

We don't need to install CUDA with cuda-redist-platform. Maybe there's some other dependency missing. Please let me know what the Dependencies tool says: https://github.com/bytedeco/javacpp-presets/wiki/Debugging-UnsatisfiedLinkError-on-Windows |

Nice tool, thank you! I tested like below and it's not working yet... It seemed to load my prebuilt OpenCV libraries that are different version from javacpp-opencv.
I have 2 questions.

Those are probably the files that have issues loading. Please check the dependencies of those modules. |

I totally forgot the documentation saying (https://github.com/bytedeco/javacpp-presets/tree/master/opencv#documentation).
Finally my fixed code works well. import org.bytedeco.javacpp.Loader;
import org.bytedeco.opencv.global.opencv_core;
import org.bytedeco.opencv.global.opencv_cudaimgproc;
import org.bytedeco.opencv.global.opencv_imgproc;
import org.bytedeco.opencv.opencv_core.GpuMat;
import org.bytedeco.opencv.opencv_cudaoptflow.FarnebackOpticalFlow;
import org.bytedeco.opencv.opencv_cudafeatures2d.ORB;
import org.bytedeco.opencv.opencv_cudaimgproc.TemplateMatching;
import org.bytedeco.opencv.opencv_java;
import java.io.IOException;
public class Main {
public static void main(String[] args) {
Loader.load(opencv_java.class);
try {
Loader.load(org.bytedeco.opencv.opencv_cudaoptflow.FarnebackOpticalFlow.class);
} catch (UnsatisfiedLinkError e) {
try {
String path = Loader.cacheResource(org.bytedeco.opencv.opencv_cudaoptflow.FarnebackOpticalFlow.class, "windows-x86_64/jniopencv_ximgproc.dll").getPath();
new ProcessBuilder("c:/DependenciesGui.exe", path).start().waitFor();
} catch (IOException|InterruptedException e1) {
e1.printStackTrace();
}
}
GpuMat mat_cuda = new GpuMat();
System.out.println("mat_cuda succeed");
ORB orb_cuda = ORB.create();
System.out.println("orb_cuda succeed");
TemplateMatching temp_cuda = opencv_cudaimgproc.createTemplateMatching(opencv_core.CV_8UC1, opencv_imgproc.TM_SQDIFF);
System.out.println("temp_cuda succeed");
FarnebackOpticalFlow optflow_cuda = FarnebackOpticalFlow.create();
System.out.println("optflow_cuda succeed");
}
}and run Thank you for your help @saudet !! |

We shouldn't need to load |
|
Fix included in version 1.5.4! Thanks for reporting |
I make a opencv + cuda test code like below and confirmed to success of
opencv_cudafeatures2dandopencv_cudaimgproc, butopencv_cudaoptflowfailed withjava.lang.UnsatisfiedLinkError: no jniopencv_ximgproc in java.library.path: [...].Does anybody know why?
