深度學習常用軟件包：
- Theano 偏底層，實現了GPU矩陣運算
- Pylearn2 模塊化
- scikit-neuralnetwork
scikit-neuralnetwork
scikit-neuralnetwork是對pylearn2的神經網絡封裝，兼容scikit-learn。
GitHub中軟件包以及安裝步驟
https://github.com/aigamedev/scikit-neuralnetwork
通過CMD輸入
pip install scikit-neuralnetwork
自動安裝依賴
https://pypi.python.org/pypi/scikit-neuralnetwork
在python中
import theano
出現：
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：需要安裝g++編譯器
直接CMD中輸入
conda install mingw libpython
出現
