This folder contains a amalgamation generation script to generate the entire mxnet library into one file. Currently it supports generation for predict API, which allows you to run prediction in platform independent way.

Type make will generate the following files

• mxnet_predict-all.cc
  • The file you can used to compile predict API
• ../lib/libmxnet_predict.so
  • The dynamic library generated for prediction.

You can also checkout the Makefile

The only dependency is a BLAS library.

This module is created by Jack Deng.

Setup NDK and build your standalone toolchain. Instructions Use the Advanced Method!!! Build OpenBlas for Android: Build OpenBlas Type make ANDROID=1 Build will FAIL the first time as expected. Before this issue gets fixed, you need to manually remove include statements from mxnext_predict-all.cc and add <common.h> back. Here is the diff you want to apply:

Type make ANDROID=1 again to continue the build.

In most cases you will want to use jni_libmxnet_predict.so. It contains the JNIs. In case you want to build your own JNI, link with libmxnet_predict.o
