debian上安装matplotlib sklearn

安装机器学习环境

配置pip源

[global]
index-url = http://pypi.v2ex.com/simple [install]
trusted-host = pypi.v2ex.com

或者

[global]
index-url = http://mirrors.aliyun.com/pypi/simple trusted-host = mirrors.aliyun.com

安装过程

apt-get install build-essential python-dev libfreetype6-dev libpng-dev python-virtualenv

apt-get install libatlas-dev libatlas3gf-base

pip install numpy

pip install matplotlib

[出现错误]

freetype: no [The C/C++ header for freetype2 (ft2build.h)

could not be found. You may need to install the

development package.]

[解决方案]

把这个文件拷出来，能让gcc找到就可以了

$ cp /usr/include/freetype2/ft2build.h /usr/include/ft2build.h

pip install matplotlib

最后安装sklearn

官方推荐用Canopy and Anaconda 来安装，可是我下载得比较慢。鼓励大家也还是用这个来安装试试。

Installing scikit-learn¶

参考

Installing scipy on redhat with error “no lapack/blas resources found”

apt-get install libblas-dev liblapack-dev
apt-get install gfortran

pip install scipy

pip install sklearn

至此安装完成。

另外的一些参考

wget http://download.savannah.gnu.org/releases/freetype/freetype-2.6.1.tar.bz2 tar -xjvf freetype-2.6.1.tar.bz2
cd freetype-2.6.1/
./configure --prefix=/usr/local
make
sudo make install

即使已经安装了freetype2

$ pacman -S freetype2

$ pacman -Ql freetype2 | grep ft2build.h

freetype2 /usr/include/freetype2/ft2build.h

结果只要把这个文件拷出来，能让gcc找到就可以了

$ cp /usr/include/freetype2/ft2build.h /usr/include/ft2build.h
