前言

由於課題需要，編譯了Caffe的python介面。下面的部落格內容就將整個過程和遇到的問題記錄下來，若是各位看官遇到了相似的情況可能會給你帶來幫助。

1. 環境準備

sudo apt-get update
sudo apt-get install python-pip puthon-dev python numpy
sudo apt-get install python-pip python-dev python-numpy
sudo apt-get install gfortran
sudo pip install -r $caffe_root/python/requirements.
 
txt

說明：$caffe_root是指caffe的目錄，也就是解壓的目錄。在進行上面安裝，當到安裝IPython（對Python2.7.x）的時候可能會出現限免的情況導致安裝不成功。

IPython 6.0+ does not support Python 2.6, 2.7, 3.0, 3.1, or 3.2.
    When using Python 2.7, please install IPython 5.x LTS Long Term Support version.
    Beginning with IPython 6.0, Python 3.3 and above is required.

    See IPython `README.rst` file
 
 for more information:

        https://github.com/ipython/ipython/blob/master/README.rst

    Python sys.version_info(major=2, minor=7, micro=6, releaselevel='final', serial=0) detected.
    Your pip version is out of date, please install pip >= 9.0.1. pip 1.5.4 detected.

    Complete output from command
 
 python setup.py egg_info:    

IPython 6.0+ does not support Python 2.6, 2.7, 3.0, 3.1, or 3.2.
When using Python 2.7, please install IPython 5.x LTS Long Term Support version.
Beginning with IPython 6.0, Python 3.3 and above is required.

這裡是說我們安裝的IPython的版本太高了，需要安裝IPython5左右的。這裡就有兩種辦法去解決：
辦法1：原始碼安裝

wget https://codeload.github.com/ipython/ipython/zip/5.x -o ipython-5.x.zip
unzip ipython-5.x.zip
cd ipython-5.x
# The [test] extra ensures test dependencies are installed too:
pip install .[test]
#Do not invoke setup.py directly as this can have undesirable consequences for further upgrades. We do not recommend using easy_install either.
ln -sf /usr/local/bin/ipython /usr/bin/ipython
ipython -V

方法二：不知道那個版本可以用，那就讓系統來做

sudo pip install ipython==8888 #現指定一個不存在的版本以檢視可用版本，發現5版本中有5.3.0（你的可能不一樣）

sudo pip install ipython==5.0.0
sudo pip install pydot

2. 編譯pycaffe

這裡的編譯就比較簡單了

make clean
make -j4
make pycaffe

3. 繪製網路結構圖

這裡以繪製mnist使用的網路結構為例進行繪製網路結構。當前命令所在的目錄在$caffe_root/python/下

python draw_net.py ../examples/mnist/lenet.prototxt mnist.png

可能會出現如下錯誤

Drawing net to mnist.png
Traceback (most recent call last):
  File "draw_net.py", line 58, in <module>
    main()
  File "draw_net.py", line 54, in main
    phase)
  File "/home/sucker/Desktop/install_pakages/caffe-1.0/python/caffe/draw.py", line 244, in draw_net_to_file
    fid.write(draw_net(caffe_net, rankdir, ext, phase))
  File "/home/sucker/Desktop/install_pakages/caffe-1.0/python/caffe/draw.py", line 223, in draw_net
    return get_pydot_graph(caffe_net, rankdir, phase=phase).create(format=ext)
  File "/usr/local/lib/python2.7/dist-packages/pydot.py", line 1883, in create
    prog=prog))
Exception: "dot" not found in path.

解決辦法

sudo apt-get install graphviz
