刚准备学习tensorflow，发现昨天刚发布了2.0大版本更新，好开心，然而。

> pip install tensorflowSuccessfully installed absl-py-0.7.0 astor-0.7.1 gast-0.2.2 grpcio-1.19.0 h5py-2.9.0 keras-applications-1.0.7 keras-preprocessing-1.0.9 markdown-3.0.1 mock-2.0.0 pbr-5.1.3 protobuf-3.7.0 tensorboard-1.13.1 tensorflow-1.13.1 tensorflow-estimator-1.13.0 termcolor-1.1.0 werkzeug-0.14.1 wheel-0.33.1

安装成功，版本是1.13.1，并不是刚更新的2.0，而且import报错。

import tensorflow as tfTraceback (most recent call last):  File "C:\Program Files\Python37\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in 
   
        from tensorflow.python.pywrap_tensorflow_internal import *  File "C:\Program Files\Python37\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 28, in

我的系统是win10-x64，cpu是奔腾E5700

最后尝试使用Anaconda安装。

安装成功，可是安装好的版本是conda自动匹配到的：python-3.6.2+tensorflow-1.2.1。（可能真是cpu或者系统的兼容问题？）

> conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ > conda config --set show_channel_urls yes > conda create -n tensorflow python=3.7.1 > activate tensorflow > conda install tensorflow

下次直接 > python 进入时，import依然会报错。所以进入tensorflow需要再次执行命令

> activate tensorflow > python
