TensorFlow报错：failed call to cuDevicePrimaryCtxRetain: CUDA_ERROR_INVALID_DEVICE

版本：

tensorflow-gpu

原因：

在创建session时没有使用我想让它用的gpu

解决方案：

1. 在python程序中：

import os
os.environ["CUDA_VISIBLE_DEVICES"] = "0"

2. 运行时：

CUDA_VISIBLE_DEVICES=0 python **.py

3. 直接在环境变量中 export

export CUDA_VISIBLE_DEVICES=‘0‘
python **.py

git报错failed to push some refs to '[email protected]:Markprint/github.git'

这个不知名小错误用了我两天的空余时间mmp 就是这里报的错输入 git push origin master -f 解释为: 远程分支上存在本地分支中不存在的提交,往往是多人协作开发过程中遇到的问题,可以先fetch再merge,也就是pull,把远程分支上的提交合并到本地分支之后再push.如果你确定远程分支上那些提交都不需要了,那么直接git push origin master -f,强行让本地分支覆盖远程分支终于有了,以后还需要具体研究一下虽然用的github,但是要推广一下
