gpu相关

1、查看cuda版本

 cat /usr/local/cuda/version.txt

2、查看cudnn版本

 cat /usr/local/cuda/include/cudnn.h  | grep CUDNN_MAJOR -A 2

3、tensorflow下载慢

pip install tensorflow -i https://pypi.douban.com/simple

4、tensorflow安装 报错 ModuleNotFoundError: No module named 'setuptools'

 pip3 install --upgrade setuptools

sudo pip3 install tensorflow-gpu==1.13.1  -i https://pypi.douban.com/simple

sudo pip3 install --upgrade --force-reinstall tensorflow-gpu==1.9.0 --user -i https://pypi.douban.com/simple
