opencv_imgproc342 in java.library.path after update to the new version about opencv HOT 4 CLOSED

Hi @hurschler, are you sure that you are using org.openpnp.opencv and not another package? This package does not use bytedeco.javacpp and I don't see any references to this package in your repo: https://github.com/deeplearning4j/deeplearning4j/search?utf8=%E2%9C%93&q=openpnp&type=

Thanks,

In the Code that I use is a NativeImageLoader Class (org.datavec.image.loader.NativeImageLoader). And this Class create another Class new Mat() -> org.bytedeco.javacpp.opencv_core. The static initialization process try to load a native lib. And I think its a part of opencv wich is not found (opencv_core$AbstractArray.(opencv_core.java:109)).

Ok sorry maybe it's the wrong opencv project right?

HI @hurschler, yes, wrong project I'm afraid. I think you are looking for this one: https://github.com/bytedeco/javacv
