今天继续在虚拟机上搭建tensorflow环境。

遇到了几个问题：

1、“IOError: [Errno 13] Permission denied:”ubuntu的权限问题，最后用一行“sudo su"解决了。

2、起初错装了gpu的tensorflow（https://mirrors.tuna.tsinghua.edu.cn/tensorflow/linux/），可以成功安装但无法调用会报错。

3、关于pip install -i:

    pip install tensorflow -i https://mirrors.tuna.tsinghua.edu.cn/tensorflow/linux/cpu/tensorflow-1.3.0rc0-cp27-none-linux_x86_64.whl

与

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/   https://mirrors.tuna.tsinghua.edu.cn/tensorflow/linux/cpu/tensorflow-1.3.0rc0-cp27-none-linux_x86_64.whl

这两个是不一样的的一个就会报错，第二才是从指定地方安装包的方法。

（刚开始，没看清课件，写错了，郁闷了老会。要认真啊！）
