篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Mac OSX (EI Capitan)搭建Caffe环境并配置python接口相关的知识,希望对你有一定的参考价值。


Caffe是一个清晰而高效的深度学习框架,其作者是博士毕业于UC Berkeley的贾扬清。Caffe是纯粹的C++/CUDA架构,支持命令行、Python和MATLAB接口;可以在CPU和GPU直接无缝切换。我在MacbookPro(无NVIDIA显卡)上大费周章地配置了Caffe的环境,并花了许多时间配置其python接口。


一、下载Caffe

github上的下载地址:https://github.com/BVLC/caffe
进入到下载后的路径,并复制
Makefile.config.example 重命名为 Makefile.config (我电脑的用户名是cuiqi,注意修改)
git clone https://github.com/BVLC/caffe.git
cd /Users/cuiqi/Downloads/caffe-master && cp Makefile.config.example Makefile.config

二、安装相关依赖

   对于需要python接口的情况,需要以下依赖

1. CUDA 
由于我的Mac没有NVIDIA的GPU,所以只能使用CPU_ONLY模式,需要在 Makefile.config 中修改 CPU_ONLY := 1
2. BLAS via ATLAS, MKL, or OpenBLAS. # Basic Linear Algebra Subprograms,基础线性代数程序集 3. Boost >= 1.55 # Deepdream是用Python接Caffe,因此还需要 boost.python 支持
brew install boost --with-python
brew install boost-python

4. OpenCV >= 2.4 including 3.0 5. protobuf, glog, gflags
brew install protobuf
brew install glog
brew install gflags
6. IO libraries hdf5, leveldb, snappy, lmdb
brew install leveldb
brew install lmdb
brew tap homebrew/science
brew install homebrew/science/hdf5
# python driver for hdf5
pip install h5py
7. numpy for python
brew install numpy

三、修改Makefile.config中相应的路径

   如果要使用Anaconda的python环境可以在Makefile.config中取消相应的注释,我试过这样做,可是在CMAKE的时候并不奏效:

Python:

Interpreter : /usr/bin/python2.7 (ver. 2.7.10)

Libraries : /usr/lib/libpython2.7.dylib (ver 2.7.10)

NumPy : /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/core/include (ver 1.8.0rc1)

 所以我放弃了使用Anaconda,改使用系统自带的python。

PYTHON_INCLUDE := /usr/include/python2.7  

  由于我使用了Homebrew安装了numpy,所以我在makefile.config中修改相应的numpy路径

PYTHON_INCLUDE := /usr/include/python2.7 /usr/local/Cellar/numpy/1.11.2/lib/python2.7/site-packages/numpy/core/include/numpy/core/include

  我的Makefile.config文件:

四、编译

  使用cmake工具,将cmake的sourcecode设为caffe的路径,在caffe目录下建立build文件夹,并将cmake的build路径设为该build的路径,configure,generate。

  此时打开终端工具进入build目录下,make。

make all
make test
make runtest
make pycaffe

  如果没有出现错误,并全部通过后,此时make告一段落,但是并不能确定可以在python中import。

  在终端上:

vi etc/profile

  或

sudo vi /etc/profile

  进入修改系统的环境变量,将 caffe/python/添加到Python系统路径:

export PYTHONPATH=path to caffe/python:$PYTHONPATH
例如:
export PYTHONPATH=/Users/cuiqi/Downloads/caffe-master/python:$PYTHONPATH

  终端输入python,确认这个python环境是刚刚在makefile.config中设定的那个,可以 which python 确认。由于我没有使用Anaconda,我的是

  /usr/local/bin/python ,确认为刚刚在makefile.config中设定的路径。

  >>> import caffe

  # 可能的错误

  ImportError: No module named skimage.io

  # 解决

   pip install scikit-image
