Build TensorFlow 1.9 with AVX2/FMA on macOS High Sierra 10.13 (updated July 22, 2018)

These instructions were inspired by Mistobaan's gist, ageitgey's gist, and mattiasarro's tutorial, and Philster's gist

Background

I always encountered the following warnings when running my scripts using the precompiled TensorFlow Python package:

W tensorflow/core/platform/cpu_feature_guard.cc:45] The TensorFlow library wasn't compiled to use SSE4.1 instructions, but these are available on your machine and c

Training TensorFlow models in C++

Python is the primary language in which TensorFlow models are typically developed and trained. TensorFlow does have bindings for other programming languages. These bindings have the low-level primitives that are required to build a more complete API, however, lack much of the higher-level API richness of the Python bindings, particularly for defining the model structure.

This file demonstrates taking a model (a TensorFlow graph) created by a Python program and running the training loop in C++.

FASTBuild is an open-source distributed build system, which could be a free alternative to Incredibuild. Unreal Engine 4 (UE4) does not support FASTBuild natively, however it's not hard to integrate it manually.

Integrate FASTBuild with UE4

Install FASTBuild

We assume you already have the full UE4 source code. First you'll need to grab the latest FASTBuild tools from here. We use v0.93 Windows x64 version in this tutorial. Download it and extract all the files. Here you have several choices:

Place the files under any folder which could be found with your system's PATH environment variable. To see where these folders are, run the PATH command in a command prompt window;
Place the files under the Engine\Binaries\ThirdParty\FASTBuild folder of your engine. This is the recommended place;
Place the files anywhere you like. This is not recommended because you'll have to hard-code the path later.

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.
