安裝python和pip

root@k-Lenovo:~/caffe# python --version
Python 2.7.6

pip是專門用於安裝python各種依賴庫的，所以我們這裡安裝一下pip1.5.6 http://pan.baidu.com/s/1cfsHv4

有些電腦可能會提示 no moudle name setuptools 的錯誤，這是沒有安裝setuptools的原因。那就需要先安裝一下setuptools, 到https://pypi.python.org/packages/source/s/setuptools/setuptools-19.2.tar.gz 下載安裝包setuptools-19.2.tar.gz，然後解壓執行

安裝pyhon介面依賴庫

在caffe根目錄的python資料夾下，有一個requirements.txt的清單檔案，上面列出了需要的依賴庫，按照這個清單安裝就可以了。

在安裝scipy庫的時候，需要fortran編譯器（gfortran)，如果沒有這個編譯器就會報錯，因此，我們可以先安裝一下。

首先回到caffe的根目錄，然後執行安裝程式碼：

root@k-Lenovo:~/pip-1.5.6# cd ~/caffe
root@k-Lenovo:~/caffe# sudo apt-get install gfortran

root@k-Lenovo:~/caffe# cd python/
root@k-Lenovo:~/caffe/python# ls
caffe  classify.py  CMakeLists.txt  detect.py  draw_net.py  requirements.txt
root@k-Lenovo:~/caffe/python# for req in $(cat requirements.txt); do sudo pip install $req; done

root@k-Lenovo:~/caffe/python# cd ..
root@k-Lenovo:~/caffe# ls
build            CONTRIBUTORS.md  examples    Makefile.config          README.md
caffe.cloc       data             include     Makefile.config.example  scripts
cmake            distribute       INSTALL.md  matlab                   src
CMakeLists.txt   docker           LICENSE     models                   tools
CONTRIBUTING.md  docs             Makefile    python
root@k-Lenovo:~/caffe# sudo pip install -r python/requirements.txt

編譯python介面

首先，將caffe根目錄下的python資料夾加入到環境變數

開啟配置檔案bashrc

root@k-Lenovo:~/caffe# sudo vi ~/.bashrc

export PYTHONPATH=/root/caffe/python:$PYTHONPATH  #追加到最後

root@k-Lenovo:~/caffe/python# sudo ldconfig

root@k-Lenovo:~/caffe# sudo make pycaffe
CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp
touch python/caffe/proto/__init__.py
PROTOC (python) src/caffe/proto/caffe.proto

檢視 python/caffe/ 目錄下，除了原先的一堆py字尾檔案，現在多出了一堆pyc字尾檔案

/root/caffe/python/caffe
root@k-Lenovo:~/caffe/python/caffe# cd ..
root@k-Lenovo:~/caffe/python# ls
caffe  classify.py  CMakeLists.txt  detect.py  draw_net.py  requirements.txt
root@k-Lenovo:~/caffe/python# python
Python 2.7.6 (default, Jun 22 2015, 17:58:13)

  warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')
>>>

root@k-Lenovo:~/caffe/python# cd caffe/
root@k-Lenovo:~/caffe/python/caffe# ls
_caffe.cpp     classifier.pyc  detector.pyc  __init__.py   io.pyc        proto        test
_caffe.so      coord_map.py    draw.py       __init__.pyc  net_spec.py   pycaffe.py
classifier.py  detector.py     imagenet      io.py         net_spec.pyc  pycaffe.pyc

安裝好caffe後，將caffe/python的路徑新增到使用者環境變數~/.bashrc中：
export PYTHONPATH=/root/caffe/python:$PYTHONPATH #這個是之前寫的

或者執行：

root@k-Lenovo:~/caffe# export PYTHONPATH=/root/caffe/python:$PYTHONPATH

安裝jupyter

學會了python還不行，還得學習一下ipython，後者更加方便快捷，更有自動補全功能。而ipython notebook是ipython的最好展現方式。最新的版本改名為jupyter notebook,我們先來安裝一下。

root@k-Lenovo:~/caffe/python# sudo pip install jupyter

安裝成功後，執行notebook

root@k-Lenovo:~/caffe/python# jupyter notebook
