为什么现在pip下载tensorflow-gpu这么难？

Question

为什么现在pip下载tensorflow-gpu还要mxnet的GPU版本都这么难，完全下载不下来，重复了无数次都是下到中途就卡住报错了，换了各种国内源也不行，在安装包前面添加 --upgrade也不行，下载命令如下：
pip install --upgrade tensorflow-gpu==1.14.0 --default-timeout=5000 -i https://pypi.tuna.tsinghua.edu.cn/simple
报错是这样的：
ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE
REQUIREMENTS FILE. If you have updated the package versions, please
update the hashes. Otherwise, examine the package contents carefully;
someone may have tampered with them.

Answer 1

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple tensorflow-gpu 试试
