Problem

I have tried to replace the Mxnet models in WhatsThis with my own Caffe models that I ported to Mxnet with https://github.com/Microsoft/MMdnn . When I run the application, I get a white screen with no elements and the application crashes. Please advise. Assume that the model is correct as it works perfectly on a PC Mxnet environment. I only changed the model, did nothing else to get this behavior.

Solutions that I tried

  • Change the input shape ( model is set for 1,3,128,128) - problem remains

Files used

symbol.json

    What is the error message you receive when your app crashes? – Sergei Jun 19 '18 at 23:01
  • @Sergei , thanks for the comment I updated the question with the log from logcat. You can find the log here: [log](https://pastebin.com/raw/TEY3ZD0R) – Augustinas Makevičius Jun 20 '18 at 07:40
  • First error is "Couldn't open the File - /data/system/users/0/personalist.xml - No such file or directory" - I don't really know what this file is. The next from that is MxnetException is not found, so maybe there is something wrong with MXNet installation on Androdi? Have you tried to run some really simple neural network on android to make sure that the Android version of it works? – Sergei Jun 21 '18 at 00:26

Check that the application works using the models provided in the repository, to confirm that Android can use the MXNet library correctly. Use the instructions on how to build the MXNet Amalgamation here if things are not working with the default models.

You could also try some other methods of converting your model. ONNX is supported by MXNet and given you're converting a Caffe model, you should be able to use the MXNet Caffe Converter too.
