深度学习常用软件包：
- Theano 偏底层，实现了GPU矩阵运算
- Pylearn2 模块化
- scikit-neuralnetwork
scikit-neuralnetwork
scikit-neuralnetwork是对pylearn2的神经网络封装，兼容scikit-learn。
GitHub中软件包以及安装步骤
https://github.com/aigamedev/scikit-neuralnetwork
通过CMD输入
pip install scikit-neuralnetwork
自动安装依赖
https://pypi.python.org/pypi/scikit-neuralnetwork
在python中
import theano
出现：
WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.
Reason：Try installing the g++ compiler.Python is rather slow, so for performance-critical parts you need a compiled language such as C++.
solution：需要安装g++编译器
直接CMD中输入
conda install mingw libpython
出现
an http error occured when trying to retrieve....
初步认为是网络问题，可以换个网络或者换个时间段再执行上述命令。
