ValueError: You are trying to use the old GPU back-end. It was removed from Theano. Use device=cuda*

在使用theano利用gpu跑python程序的时候报错如下：

ValueError: You are trying to use the old GPU back-end. It was removed from Theano. Use device=cuda* now. See https://github.com/Theano/Theano/wiki/Converting-to-the-new-gpu-back-end%28gpuarray%29 for more information.

解决方法：
1： vim ~/.bashrc
2：添加如下命令：

export THEANO_FLAGS='mode=FAST_RUN,device=cpu,floatX=float32'

3：使修改的theano设置生效：

source ~/.bashrc

4：编辑theano对于gpu的配置文件：

vim ~/.theanorc

5：添加内容如下：

[global]
device = cuda
floatX=float32
[nvcc]
flags=--machine=64
[lib]
cnmem=100

结束
