先anaconda
open anaconda prompt
$ conda create -n tensorflow python=3.5
确保名叫tensorflow的环境已经被成功添加：conda info --envs
$ activate tensorflow.
$ conda install tensorflow
Verifying the Installation
$python
import tensorflow as tf
错误为ImportError: cannot import name ‘weakref‘，那么请在tensorflow的的安装位置中找到名为的tf_should_use.py文件，将第28行的from backports import weakref替换为import weakref
open pycharm
interpreter->add python interpreter-> existing environment->LIJINGYU070/Anaconda3/envs/tensorflow/python.exe
package + ->tensorflow->install
package ‘tensorflow‘ installed successfully
