在 Mac 上配置 Caffe 大概花了半天多的時(shí)間羹蚣，時(shí)間主要是花在解決各種奇怪的 error 上面了摄职。在此記錄一下配置的過(guò)程和遇到的問(wèn)題几颜，希望今后能少走一些彎路脸候。
安裝過(guò)程
安裝 Cuda穷娱。雖說(shuō)打算無(wú)腦運(yùn)行绑蔫，但還是安上了。
安裝 Homebrew 工具泵额。
Homebrew 安裝 Caffe 依賴配深，有些安裝速度比較慢，耐心啊嫁盲。
# general dependencies
$ brew install -vd snappy leveldb gflags glog szip lmdb
$ brew tap homebrew/science
$ brew install hdf5 opencv
# with Python pycaffe needs dependencies built from source
$ brew install --build-from-source --with-python -vd protobuf
$ brew install --build-from-source -vd boost boost-python
$ brew install homebrew/science/openblas
- 修改文件篓叶。可以使用命令：
$ brew edit openCV
或者由路徑 /usr/local/Homebrew/Library/Taps/homebrew/homebrew-science/opencv.rb 直接尋找文件羞秤。
替換：
args << "-DPYTHON#{py_ver}_LIBRARY=#{py_lib}/libpython2.7.#{dylib}"
args << "-DPYTHON#{py_ver}_INCLUDE_DIR=#{py_prefix}/include/python2.7"
為：
args << "-DPYTHON_LIBRARY=#{py_prefix}/lib/libpython2.7.dylib"
args << "-DPYTHON_INCLUDE_DIR=#{py_prefix}/include/python2.7"
- 下載 Caffe 源碼并生成配置文件缸托。
$ git clone https://github.com/bvlc/caffe.git
$ cd caffe
$ cp Makefile.config.example Makefile.config
- 修改文件
Makefile.config。主要修改的地方有：- 去掉注釋符瘾蛋，設(shè)置為 CPU_ONLY 模式俐镐。
- 配置 BLAS。
- 設(shè)置 Anaconda 路徑哺哼。
- 在 mac OS Sierra 環(huán)境下設(shè)置禁止使用 LevelDB（不兼容）佩抹。

Q ?= @
- 編譯、測(cè)試取董。
$ make all
$ make runtest
發(fā)現(xiàn)有很多 warning棍苹，但這些不會(huì)影響工作。
- 為了可以在 python 中引入模塊茵汰，需要編譯 pycaffe枢里。在之后 import 時(shí)可能出現(xiàn)錯(cuò)誤 "No module named google.protobuf.internal"，因此先要安裝 protobuf经窖。
pip install protobuf
之后編譯 pycaffe坡垫。
make pycaffe
make distribute
- 在 ".bash_profile" 中設(shè)置環(huán)境變量
PYTHONPATH。
export PYTHONPATH=/Users/Dennis/caffe/python:$PYTHONPATH
- 完成画侣。
