解决方案

原因：通常是因为网速问题导致的下载错误，导致对应的哈希值不匹配。

第一种

# 即卸载干净之后，再重装
pip uninstall tensorflow
pip --default-timeout=100  install tensorflow

第二种

需要在pip时，添加"–upgrade“参数即可。通常这时下载还会报错timeout，因此多加一个”–default-timeout=100000" 更为保险（timeout的赋值可以视情况变化）。

pip install --upgrade --default-timeout=100000 packagename -i http://pypi.douban.com/simple
