Tflite Model not detecting objects


I downloaded the salad.tflite file from this repo android assets file and tried to use it in my own android app but the model is not detecting anything.
It is giving the below given error
```
Failed to initialize detector. Unexpected number of dimensions for output index 0: got 3D, expected either 2D (BxN with B=1) or 4D (BxHxWxN with B=1, W=1, H=1).
```
I didn't change the model.
