[theano]安装-python theano cuda

I want to learning deep learning, so config cuda is a essential step. luckily it is very easy in Ubuntu

install theano+cuda in ubuntu

1. install theano

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

b) sudo pip install Theano

2. install cuda

a) sudo apt install nvidia-331

If it is successful, we can test it with

$dkms status

If you see the response like nvidia-331, 331.38, 3.13.0-24-generic, x86_64: installed, congratulations.

b) sudo apt install nvidia-cuda-toolkit

c) Reboot your machine

d)test with

import theano
theano.test()

If you see something like Using gpu device 0: GeForce GT 740M,OK

e) config

sudo vim ~/.theanorc

[global]
floatX = float32
device = gpu

OK We can enjoy the gpu.
