查看现在的tensorflow版本

(base) C:\Users\lenovo>pip show tensorflow

Required-by:

卸载已有的tensorflow

(base) C:\Users\lenovo>pip uninstall tensorflow
 
Uninstalling tensorflow-2.0.0:
 
  Would remove:
 
    c:\programdata\anaconda3\lib\site-packages\tensorflow-2.0.0.dist-info\*
 
    c:\programdata\anaconda3\lib\site-packages\tensorflow\*
 
    c:\programdata\anaconda3\lib\site-packages\tensorflow_core\*
 
    c:\programdata\anaconda3\scripts\saved_model_cli.exe
 
    c:\programdata\anaconda3\scripts\tensorboard.exe
 
    c:\programdata\anaconda3\scripts\tf_upgrade_v2.exe
 
    c:\programdata\anaconda3\scripts\tflite_convert.exe
 
    c:\programdata\anaconda3\scripts\toco.exe
 
    c:\programdata\anaconda3\scripts\toco_from_protos.exe
 
Proceed (y/n)? y
 
  Successfully uninstalled tensorflow-2.0.0

对tensorflow的安装文件进行完全的清除（https://blog.csdn.net/wipvip/article/details/82735603）

查看自己的python版本号为3.7，然后进行降级到3.6

（输入两次add channels…一长串的… 置顶清华滤镜网站）

(base) C:\Users\lenovo>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
 
(base) C:\Users\lenovo>conda config --set show_channel_urls yes
 
(base) C:\Users\lenovo>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
 
Warning: 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/' already in 'channels' list, moving to the top

设置3.6环境

(base) C:\Users\lenovo>conda create --name py36 python=3.6 anaconda

激活py3.6

(base) C:\Users\lenovo>activate py36

验证环境

(py36) C:\Users\lenovo>python --version
 
Python 3.6.1 :: Anaconda 4.4.0 (64-bit)

现在就可以安装1.4.0版本啦！！

(py36) C:\Users\lenovo>pip install tensorflow==1.4.0

验证安装成功的版本（期间有报错，但是好像也不影响？）

(py36) C:\Users\lenovo>python
 
Python 3.6.1 |Anaconda 4.4.0 (64-bit)| (default, May 11 2017, 13:25:24) [MSC v.1900 64 bit (AMD64)] on win32
 
Type "help", "copyright", "credits" or "license" for more information.
 
>>> import tensorflow as tf
>>> tf.__version__
'1.4.0'
