Error when I try to build Android app with CNTK by Unity3d

Question

I have try so many weeks for build a Android app with CNTK's CNN evaluation function(C#) by Unity. But I encountered some error that I don't know how to solve.

The processing pipeline I expect is:

1. Train the model using Keras (by python)

2. Convert model to CNTK's format

3. Use CNTK(C#)'s Evaluation function in Unity

4. Export Android APK

I successed use CNTK for evaluation an image when I just use Play button in Unity before I builded. But when it has installed in my Android phone, it showed some error like CNTK cannot initialize because it cannot find the CPU.

The error message is below:

my system Configuration:

• OS : Win10
• Unity : 2017.3
• Script Backend : Mono (I try IL2CPP but get some error)
• API Compatibility : .NET 4.6
• Build System : Gradle
• CNTK 2.4 (C#)

(I also export to android studio and use AVD (arm processor) and failed.)

and give my project folder

Any suggestion will be appreciated.

CNTK doesn't support ARM CPU now. https://github.com/Microsoft/CNTK/issues/266
