Deepdream是最近Google开源的一个很好玩的项目，让我们可以看到利用深度学习对图片进行分类时，相邻神经网络层次之间的信息传递。Deepdream是基于Caffe框架，因此主要是安装Caffe的依赖环境和Caffe框架。

1. 下载 Caffe

git clone https://github.com/BVLC/caffe.git
cd caffe && cp Makefile.config.example Makefile.config

2. 安装 Caffe 依赖

#1. CUDA is required for GPU mode.
# 不采用GPU模式，只需要在 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
# 应该是系统有自带了实现方案

#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
# OpenCV 就不用说了

#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

3. Setup for Python

官方推荐使用Anaconda，包含了大部分可能用到的Python package，然而这里有很大一个坑，Mac下面Anaconda是安装在~/anaconda目录下，要使用~/anaconda/bin/python或~/anaconda/bin/ipython而非原系统的Python，这要求所有Homebrew安装的包都必须通过Anaconda下的Python来执行，因此如果从一开始就打算用Anaconda，要注意修改环境变量。

这里不使用Anaconda，注意Makefile.config中提到：

# NOTE: this is required only if you will compile the python interface.
# We need to be able to find Python.h and numpy/arrayobject.h.
PYTHON_INCLUDE := /usr/include/python2.7

如果是通过Homebrew安装的numpy，需要添加numpy路径，否则会报错：

python/caffe/_caffe.cpp:10:10: fatal error: 'numpy/arrayobject.h' file not found

# Add this to PYTHON_INCLUDE in Makefile.config
PYTHON_INCLUDE := /usr/include/python2.7 \
    /usr/local/Cellar/numpy/1.9.2_1/lib/python2.7/site-packages/numpy/core/include

4. make

make all
make test
make runtest

make pycaffe

都通过之后将 caffe/python/添加到Python系统路径：

export PYTHONPATH=path/to/caffe/python:$PYTHONPATH

测试一下：

python
>>> import caffe

# 可能的错误
ImportError: No module named skimage.io
# 解决
pip install scikit-image

5. Run ipython notebook

git clone https://github.com/google/deepdream.git
cd deepdream && ipython notebook

需要下载 BVLC GoogleNet Model到path/to/caffe/models/bvlc_googlenet/，然后就可以基于自己的图片，让它做梦给你看！

6. Result

deepdream

Hi. I encountered a problem about the installation of protobuf.
I typed 'brew install —build-from-source —with-python —fresh -vd protobuf'
But, Homebrew asked me to type interactive mode. I don't know what it is. Could you please help me?

nice, but the opencv 2.4 will get error about cv::VideoCapture. You can modify the Makefile
LIBRARIES += opencv_imgcodecs opencv_videoio ...

Anaconda安装的时候Makefile.config里那几个变量怎么修改？很迷，thanks
