Hmm looks like a bug on my end after an update, let me look into it

Does the error change if you update this line: https://github.com/cloud-annotations/object-detection-android/blob/6197304348937a799d89225e7eed905c51cce0dc/app/src/main/java/com/example/android/tflitecamerademo/ImageClassifier.java#L99

To:

float[][][] _boxPredictionsPointer_ = new float[1][NUM_ANCHORS][4];

You’ll probably need to change other stuff too, but this should let me know if this is the underlying issue

i changed it but some more errors are coming related to it . Because of the errors i am unable to run the app.
