I need help with tensorflow + VIM3 + Android

I want to apply object detection using tensorflow using webcam in android.

I used the basic tensorflow example.

After running, object detection starts for a while, and at some point the board dies.

ERROR LOG ↓
Unable to acquire a buffer item, very likely client tried to acquire more than maxImages buffers

The code showing the error is here.↓

CameraActivity.java

 @Override
  public void onImageAvailable(final ImageReader reader) {
    //We need wait until we have some size from onPreviewSizeChosen
    if (previewWidth == 0 || previewHeight == 0) {
      return;
    }
    if (rgbBytes == null) {
      rgbBytes = new int[previewWidth * previewHeight];
    }
    try {
      final Image image = reader.acquireLatestImage();

      if (image == null) {
        return;
      }

      if (isProcessingFrame) {
        image.close();
        return;
      }
      isProcessingFrame = true;
      Trace.beginSection("imageAvailable");
      final Plane[] planes = image.getPlanes();
      fillBytes(planes, yuvBytes);
      yRowStride = planes[0].getRowStride();
      final int uvRowStride = planes[1].getRowStride();
      final int uvPixelStride = planes[1].getPixelStride();

      imageConverter =
          new Runnable() {
            @Override
            public void run() {
              ImageUtils.convertYUV420ToARGB8888(
                  yuvBytes[0],
                  yuvBytes[1],
                  yuvBytes[2],
                  previewWidth,
                  previewHeight,
                  yRowStride,
                  uvRowStride,
                  uvPixelStride,
                  rgbBytes);
            }
          };

      postInferenceCallback =
          new Runnable() {
            @Override
            public void run() {
              image.close();
              isProcessingFrame = false;
            }
          };

      processImage();
    } catch (final Exception e) {
      LOGGER.e(e, "Exception!");
      Trace.endSection();
      return;
    }
    Trace.endSection();
  }

help me…
I don’t even have basic knowledge about this machine learning…

if you want to apply object detection,you can refer VIM3&VIM3L Android NPU APP Initial Version Release
