I follow Qualcomm Neural Processing Engine official tutorial to build the Android sample app.

When the app loads model occur error. Error message following:

You need to follow the setup instructions to get the model data in the right places.

I am getting the same error. I was wondering if anyone was able to resolve this?

I tried both:

- Inception model aquired through the setup_inceptionv3.py with a -d flag on snpe-1.19.2

- Manually converted Mobilenet SSD (also following the provided tutorial steps)

I checked that the file I'm passing to SNPE.NeuralNetworkBuilder is indeed a dlc model and that it has the right contents. I would appreciate any help on this.

This problem happens because your app parsed the dlc file not correctly, while your app unzip model file not successfully, so dlc file is damaged in your phone.To solve this problem, you should push an undamaged dlc file to your phone. The undamaged file is in your app source directory, in src/main/res/raw/inception_v3.zip, unzip it and find model.dlc. then type: adb push model.dlc /storage/emulated/0/Android/data/com.qualcomm.qti.snpe.imageclassifiers/files/models/inception_v3
