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.

There is a similar problem (Why does pip fail with bad md5 hash for package?) from 2013 the solution that I tried that worked for me is this:
还有一个类似的问题（为什么PIP失败，坏MD5哈希包？）从2013年开始，我试过为我工作的解决方案是这样的：
sudo pip install --no-cache-dir flask
sudo pip install --no-cache-dir flask

--no-cache-dirdid not work for me in raspberry pi 4 at first.
--no-cache-dir起初在 raspberry pi 4 中对我不起作用。
Found that the problem was due to unexpected network change/failure during pip installation
发现问题是由于pip安装过程中意外的网络变化/失败
I had to download the broken .whlfile manually with wget
我不得不.whl手动下载损坏的文件wget
and install it like below:
sudo pip install scipy-1.3.0-cp37-cp37m-linux_armv7l.whl
并像下面一样安装它：
sudo pip install scipy-1.3.0-cp37-cp37m-linux_armv7l.whl
followed by
sudo pip install --no-cache-dir keras
其次是
sudo pip install --no-cache-dir keras
Then it worked.
然后它起作用了。

Looks like a cache problem, the cached package is different from REQUIREMENTS.
貌似是缓存问题，缓存的包和REQUIREMENTS.
Perhaps caused by last updates interruption.
可能是上次更新中断造成的。
I did this which fixed my problem:
