深度学习软件包scikit-neuralnetwork 的安装

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 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 络问题，可以换个 络或者换个时间段再执行上述命令。
