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:

object-detection-android/app/src/main/java/com/example/android/tflitecamerademo/ImageClassifier.java

Line 99 in 6197304

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

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.

I changed the line u said and i also changed some of the things and it worked fine . Thanks for the help

Great! Do you mind making a pull request with the changes?

App Crashed showing this on logcat when i was trying to detect the image .
