在ubuntu中安装theano相对于在window上安装简单很多。

如果你是Ubuntu 16.04系统

安装流程如下：

sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ libopenblas-dev git
sudo pip install Theano

# cuda 7.5 don‘t support the default g++ version. Install an supported version and make it the default.
sudo apt-get install g++-4.9

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 20
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 10

sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 20
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-5 10

sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 30
sudo update-alternatives --set cc /usr/bin/gcc

sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 30
sudo update-alternatives --set c++ /usr/bin/g++

# Work around a glibc bug
echo -e "\n[nvcc]\nflags=-D_FORCE_INLINES\n" >> ~/.theanorc

 

如果你是Ubuntu 11.10 到 14.04版本

安装流程如下：

sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ libopenblas-dev git
sudo pip install Theano

如果你的版本是Ubuntu 11.04

安装流程如下：

sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ git libatlas3gf-base libatlas-dev
sudo pip install Theano

以上安装是基于python2 的

 

在版本Ubuntu 14.04 上如果你想使用python3 请将上述的

sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ libopenblas-dev git

修改为：

sudo apt-get install python3-numpy python3-scipy python3-dev python3-pip python3-nose g++ libopenblas-dev git

 

 

 

使用下述代码验证python包有没有安装成功

1. NumPy (~30s): 

   python -c "import numpy; numpy.test()"

    

2. SciPy (~1m): 

   python -c "import scipy; scipy.test()"

    

3. Theano (~30m):

    python -c "import theano; theano.test()"
