ImportError: Interpreter change detected while importing xmlsec

Question

我有一个 Django 服务，我最近在其中添加了 OneLogin SSO。在本地机器上一切正常，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.

我正在使用 python 3.5.1 和 Django 1.11，python3-saml 用于 SSO。机器在 AWS 上使用 amazon AMI。

事实证明，我们将 uwsgi 与线程一起使用，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 应用程序的 ini file 以使用单一解释器。
