无虚拟环境,进不同的python版本
python2 \\进Python2
python3 \\进python3.5
python3.6 \\进python3.6
升级ubuntu中自带的3.5,新安装3.6
$sudo add-apt-repository ppa:jonathonf/python-3.6
$ sudo apt update
$ sudo apt install python3.6
pip3 //python3安装
pip //python安装
首先,安装virtualenv,在默认的python2下的pip就行:
$ [sudo] pip install virtualenv
创建虚拟环境:
$ virtualenv -p /usr/bin/python3.6 py36
激活虚拟环境:
$ source py36/bin/activate
你会注意到shell的提示符行前多了(py36)字样,这样你就可以放心的使用python3做开发了。先下载个三方库试试吧
pip install httplib2
大功告成了!
如果要退出python3虚拟环境,输入命令
$ deactivate
即可。

安装cuda8.0
下载地址:https://developer.nvidia.com/cuda-80-ga2-download-archive
我们下载好cuda后直接放在home目录下,直接使用:
sudosh cuda_8.0.27_linux.run
之后一直按空格到100%后输入accept接受条款,
输入no不安装NVIDIA驱动,因为我们已经在上面安装过了;
输入y安装cuda8.0工具,回车使用默认路径安装cuda8.0工具,
输入y使用’sudo’命令,接着输入密码;
输入n不安装指向/usr/local/cuda的符号连接(也可选择y安装符号连接);
输入y安装cuda8.0的实例,我们可以用此来检验cuda是否安装成功,回车选择默认路径安装;
接着我们就等待cuda安装成功。
cuda环境配置
建立软连接;
设置环境变量,终端输入
sudo gedit /etc/profile (一般使用gedit来修改,很方便,如果你喜欢vim也可以用vim)
在末尾加入
PATH=/usr/local/cuda-8.0/bin:$PATH
export PATH
保存后,创建链接文件
sudo gedit /etc/ld.so.conf.d/cuda.conf
增加下面一行
/usr/local/cuda-8.0/lib64
最后在终端输入sudo ldconfig使链接生效。
安装cudnn

cudnn对应版本不对
参考tensorflow网页:https://www.tensorflow.org/install/install_sources#common_installation_problems
这不坑爹嘛
cudnn6 对应 cuda8.0

cuda sample 测试
打开CUDA 8.0 Samples默认安装路径,终端输入
cd /home/its/NVIDIA_CUDA-8.0_Samples (its是我的用户名)
sudo make all –j16 (16核,根据你的电脑配置,核越多运行越快)
- 下面的错误我没有出
出现“unsupported GNU version! gcc versions later than 5.3 arenot supported!”的错误,这是由于GCC版本过高,在终端输入
cd /usr/local/cuda-8.0/include
sudo gedit host_config.h
ctrl+f寻找有“5.3”的地方,只有一处,如下
# if __GNUC__ > 5 || (__GNUC__ == 5 && __GNUC_MINOR__ > 3)
#error -- unsupported GNU version! gcc versions later than 5.3 are notsupported!
将3改成9,这样在GCC版本大于5.9的时候才报错,即
# if __GNUC__ > 5 || (__GNUC__ == 5 && __GNUC_MINOR__ > 9)
- 从这开始继续make
保存退出,继续在终端输入
sudo make all –j16 (16核)
完成后继续向终端输入
cd bin/x86_64/linux/release
./deviceQuery
出现下图的输出则说明cuda配置正常
出现输出
