pylearn2安装及测试

from http://blog.csdn.net/lucktroy/article/details/9466369

Pylearn2 是建立在Theano之上的一个机器学习库，可以参考：http:///software/pylearn2/

早前我已经用《Install Theano in Linux without root authority (sodu)》，所以现在也只需要仿照着安装即可。

1. Download:

[plain] view plain copy

print?

1. $ git clone git://github.com/lisa-lab/pylearn2.git  

2. 配置环境变量，我一般用.bash_profile, 也可以放在.bashrc里

[plain] view plain copy

print?

1. export PYLEARN2_DATA_PATH=/path/to/data  

3. 安装，进入pylearn2

[plain] view plain copy

print?

1. $ python setup.py build  

[plain] view plain copy

print?

1. $ python setup.py install --prefix=$PYTHON_HOME
