Windows10系统用pip3安装Tensorflow指定版本（之前安装的2.1.0版本太高了）：
(tensorflow) C:\Users\XXX>pip3 install tensorflow==1.2.1

使用豆瓣镜像安装：
pip install tensorflow==1.2.1 -i /simple
Looking in indexes: /simpleWARNING: The repository located at is not a trusted or secure host and is being ignored.

直接按照提示加上--trusted-host：

类似的错误：
Looking in indexes: /pypi/simple/WARNING: The repository located at is not a trusted or secure host and is being ignored. If this repository is available via HTTPS we recommend you use HTTPS instead, otherwise you may silence this warning and allow it anyway with '--trusted-host '.ERROR: Could not find a version that satisfies the requirement tqdm (from versions: none)ERROR: No matching distribution found for tqdmWARNING: The repository located at is not a trusted or secure host and is being ignored.

若镜像源中是http，则可以尝试按照提示直接把http改为https：
pip install tqdm -i /pypi/simple/
--------------------------------------------------------------------------------------------------------------------------------------------------------
需要把-i去掉：
pip3 install tensorflow==1.2.1 --trusted-host /simple
运行一段时间，还是会报一开始的一大堆错误：

感觉是网络的问题，打算换镜像源（参考链接：/microman/p/6107879.html）一个一个试：

其它镜像：
阿里云：/pypi/simple/
中国科技大学 https://pypi.mirrors./simple/
华中理工大学：/
山东理工大学：/
豆瓣：/simple/（之前试过不行）
如果还是不行可以放弃pip，尝试下载.whl文件离线安装。
