TensorflowでOSXのGPUが対応されたよ

Last updated at Posted at 2016-05-12

2018/12/16追記

いつの間にかOSXのGPU公式サポートはなくなったみたいなので、それでもGPU使いたい方はこちらのドキュメントが参考になるかもしれません。
Tensorflow 1.6 on macOS High Sierra 10.13.3 with GPU Acceleration (without disabling SIP)

2017/2/17追記

Tensorflow 1.0.0から簡単にインストールできるようになったので公式ドキュメントに従うことをおすすめします。
https://www.tensorflow.org/install/install_mac

#cuda8.0
$ brew upgrade
$ brew install coreutils
$ brew cask install cuda

#cuDNN v5.1 Library for OSXをダウンロードして 各/user/local/cuda/いかにコピー

##.bash_profile
#export CUDA_HOME=/usr/local/cuda
#export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib"
#export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:$CUDA_HOME/lib"
#export PATH="$CUDA_HOME/bin:$PATH"
#一応実行できるけどwarning出るのでリンク貼る
$ cd /usr/local/cuda/lib
$ sudo ln -s libcuda.dylib libcuda.1.dylib

$ easy_install --upgrade pip
$ easy_install --upgrade six 
$ pip install tensorflow-gpu

以下、本記事

Tensorflow公式レポジトリでIssue#664commit: Enable building with CUDA support on Mac OS XがMergeされてました。

これで正式にMacでもGPUありが使えるはずなので、早速インストールしてみましょう。

※非公式のGPU版セットアップの時と大体同じです。
->【爆速なるか!?】OSXでTensorflowのGPU版を使うためのセットアップ
※※CUDA GPUsでないと使えません

参考:How to compile tensorflow with CUDA support on OSX (Updated 2nd May 2016)

$ brew update
$ brew cask info cuda 
cuda: 7.5.20
$ bazel version
Build label: 0.2.1-homebrew      

NVIDIAからcuDNNをダウンロード つhttps://developer.nvidia.com/cudnn
Tensorflowのversion0.8はcuDNN v5、 version 0.7以下はv4
私はcudnn-7.5-osx-x64-v5.0-rc.tgzをダウンロードしました。

ファイル解凍して、所定の位置に移動

$tar xzvf ~/Downloads/cudnn-7.5-osx-x64-v5.0-rc.tgz
$sudo mv -v cuda/lib/libcudnn* /usr/local/cuda/lib
$sudo mv -v cuda/include/cudnn.h /usr/local/cuda/include

.bash_profile
export DYLD_LIBRARY_PATH=/usr/local/cuda/lib:$DYLD_LIBRARY_PATH
を追加

$ cd Tensorflowのレポ
