This repository makes possible the usage of the TensorFlow C++ library from the outside of the TensorFlow source code folders and without the use of the Bazel build system.

This repository contains two CMake projects. The tensorflow_cc project downloads, builds and installs the TensorFlow C++ library into the operating system and the example project demonstrates its simple usage.

# On Ubuntu 16.04, add ubuntu-toolchain-r PPA (for g++-6)
# sudo apt-get install software-properties-common
# sudo add-apt-repository ppa:ubuntu-toolchain-r/test
# sudo apt-get update

sudo apt-get install build-essential curl git cmake unzip autoconf autogen libtool mlocate zlib1g-dev \
                     g++-6 python python3-numpy python3-dev python3-pip python3-wheel wget
sudo updatedb

If you require GPU support on Ubuntu, please also install Bazel, NVIDIA CUDA Toolkit, NVIDIA drivers, cuDNN, and libcupti-dev package. The tensorflow build script will automatically detect CUDA if it is installed in /opt/cuda or /usr/local/cuda directories.

sudo pacman -S base-devel cmake git unzip mlocate python python-numpy wget
sudo updatedb

For GPU support on Arch, also install the following:

sudo pacman -S gcc6 bazel cuda cudnn nvidia

git clone https://github.com/FloopCZ/tensorflow_cc.git
cd tensorflow_cc

There are two possible ways to build the TensorFlow C++ library:

1. As a static library (default):
   • Faster to build.
   • Provides only basic functionality, just enough for inferring using an existing network (see contrib/makefile).
   • No GPU support.
2. As a shared library:
   • Requires Bazel.
   • Slower to build.
   • Provides the full TensorFlow C++ API.
   • GPU support.

cd tensorflow_cc
mkdir build && cd build
# for static library only:
cmake ..
# for shared library only (requires Bazel):
# cmake -DTENSORFLOW_STATIC=OFF -DTENSORFLOW_SHARED=ON ..
make && sudo make install

# cleanup bazel build directory
rm -rf ~/.cache
# remove the build folder
cd .. && rm -rf build

// example.cpp

#include <tensorflow/core/platform/env.h>
#include <tensorflow/core/public/session.h>
#include <iostream>
using namespace std;
using namespace tensorflow;

int main()
{
    Session* session;
    Status status = NewSession(SessionOptions(), &session);
    if (!status.ok()) {
        cout << status.ToString() << "\n";
        return 1;
    }
    cout << "Session successfully created.\n";
}
