深度学习环境配置
安装：
1. Pip (Python 2.7.9或以上自带pip）： sudo apt-get install pyton-pip
2. 尝试安装scikit-neuralnetwork: 需要 numpy scipy theano
sudo pip install scikit-neuralnetwork
错误：SystemError: cannot compile "python.h". Perhaps you need to install python-dev|python-devel
解决方法：
sudo apt-get update
sudo apt-get upgrade gcc
sudo apt-get install python2.7-dev
3. 安装numpy, scipy, theano：
pip install numpy scipy theano
sudo pip install numpy scipy theano (1:03:32)
错误：numpy.distutils.system_info.NotFoundError: no lapack/blas resources found
解决方法：sudo apt-get install libblas-dev liblapack-dev libatlas-base-dev gfortran
sudo pip install scipy
sudo pip install Theano
4. 安装Pylearn2
sudo pip install -e git+https://github.com/lisa-lab/pylearn2.git#egg=Package
需要git
sudo apt-get install git
5. 安装scikit-neuralnetwork
> git clone https://github.com/aigamedev/scikit-neuralnetwork.git> cd scikit-neuralnetwork; python setup.py develop
6. 测试
> sudo pip install nose> nosetests -v sknn.tests
需要安装matplotlib: sudo pip install matplotlib
错误：The following package could not be built: freetype, png
解决方法：sudo apt-get install libpng-dev
sudo apt-get install libjpeg8-dev
sudo apt-get install libfreetype6-dev
7. 视觉化显示：
> python examples/plot_mlp.py --params activation
8. 在MNIST上测试
> python examples/bench_mnist.py (sknn|lasagne)
