我有一个 Django 服务，我最近在其中添加了 OneLogin SSO。一切都在本地机器上工作正常，但在服务器上，登录视图在每个请求上都会抛出这个 ImportError 。

ImportError: Interpreter change detected - this module can only be loaded into one interpreter per process.

我将 python 3.5.1 与 Django 1.11 和python3-samlSSO 一起使用。该机器使用亚马逊 AMI 在 AWS 上。

事实证明，我们正在使用带有线程的 uwsgi，并且每个线程都在创建自己的解释器。
我们所要做的就是更新 uwsgi 应用程序ini file以使用单个解释器。
