Build TensorFlow Lite for ARM64 boards

Cross compiling

Installing the toolchain

sudo apt-get update
sudo apt-get install crossbuild-essential-arm64

If you are using Docker, you may not use sudo.

Building

Clone this Tensorflow repository. Run this script at the root of the repository to download all the dependencies:

The Tensorflow repository is in /tensorflow if you are using tensorflow/tensorflow:nightly-devel docker image, just try it.

./tensorflow/lite/tools/make/download_dependencies.sh

Note that you only need to do this once.

Compile:

./tensorflow/lite/tools/make/build_aarch64_lib.sh

This should compile a static library in: tensorflow/lite/gen/gen/aarch64_armv8-a/lib/libtensorflow-lite.a.

Native compiling

These steps were tested on HardKernel Odroid C2, gcc version 5.4.0.

Log in to your board, install the toolchain.

sudo apt-get install build-essential

First, clone the TensorFlow repository. Run this at the root of the repository:

./tensorflow/lite/tools/make/download_dependencies.sh

Note that you only need to do this once.

Compile:

./tensorflow/lite/tools/make/build_aarch64_lib.sh

This should compile a static library in: tensorflow/lite/gen/gen/aarch64_armv8-a/lib/libtensorflow-lite.a.
