通过常规方式(即sudo -H pip3 install --user numpy==1.17( 不允许使用该模块。
导入 numpy 是不可能的，也没有列在 pip3 冻结中
为了解决这个问题，我使用sudo -E pip3 install --upgrade numpy然后允许我使用该模块，当我进入 pip3 冻结时，我也可以在列表中看到它。
虽然这个问题对于 numpy 来说已经解决了，但它不适用于其他 python 模块，例如configparser 3.8.1.
这就是我迄今为止所做的
sudo -H pip3 install --user matplotlib

我希望能够在 pip3安装后直接使用这些模块，但它们未列在 pip3 冻结列表中
我认为您已经安装了多个版本的numpy。首先尝试将它们全部删除
sudo apt-get remove numpy
或
pip3 uninstall numpy
然后重新安装
尝试使用Anaconda，它还包含许多对您的工作有用的软件包。
