Java代码

val net = readNetFromTensorflow(modelPath)


        val outputLayers = listOf("feature_fusion/Conv_7/Sigmoid", "feature_fusion/concat_3")

        net.setInput(blob)

        val output = ArrayList<Mat>()

        net.forward(output, outputLayers)

按照上面的代码中提到的，我试图通过将2个输出层应用于DNN模型的转发方法来获取得分和几何图形作为输出。但是我得到这个错误。请如果您知道任何相关的信息。帮帮我。

在应用程序中获取JNI检测到的错误：在将输出层添加到DNN时，调用JNI CallIntMethodV并带有未决异常
