1. 安裝依賴
- 安裝CUDA
下載地址：https://developer.nvidia.com/cuda-toolkit-archive，本文采用的是CUDA 7.5版本。下載安裝之后，需要配置環境變量，編輯/etc/profile'，添加PATH=$PATH:/Developer/NVIDIA/CUDA-7.5/bin`。
- 安裝其它的依賴
通過Homebrew安裝所需要的其它依賴，其它依賴有gflags，snappy，glog，hdf5，lmdb ，opencv3，boost，leveldb ，protobuf，webp（運行mnist數據集會用到）。命令如下：
# 安裝軟件
$ brew install software
# 創建軟件鏈接，有的需要，例如protobuf，opencv3，opencv3需要--force
$ brew link software --force
2. 安裝caffe
在Github上下載caffe源碼，地址為：https://github.com/BVLC/caffe，下載后在caffe根目錄創建build文件夾，將Makefile.config.example文件名改為Makefile.config，修改Makefile.config文件，修改如下：
將
# CPU_ONLY := 1
改為
CPU_ONLY := 1
將
# USE_OPENCV := 0
改為
USE_OPENCV := 1
將
# OPENCV_VERSION := 3
改為
OPENCV_VERSION := 3
將下面兩行
# BLAS_INCLUDE := /path/to/your/blas
# BLAS_LIB := /path/to/your/blas
改為：
BLAS_INCLUDE := /System/Library/Frameworks/Accelerate.framework/Versions/Current/Frameworks/vecLib.framework/Versions/Current/Headers
BLAS_LIB := /System/Library/Frameworks/Accelerate.framework/Versions/Current/Frameworks/vecLib.framework/Versions/Current
執行make -j，看到下面的內容說明安裝caffe成功。
