Question

我有Django服务，最近我在其中添加了OneLogin SSO。一切在本地计算机上都可以正常工作，但是在服务器上，登录视图会在每个请求上引发此ImportError。

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

我正在将python 3.5.1与Django 1.11和python3-saml一起用于SSO。该机器在AWS上使用Amazon AMI。

原来，我们在线程中使用uwsgi，每个线程都在创建自己的解释器。
我们要做的就是更新ini file以使用单个解释器。

single-interpreter=True

ImportError：导入xmlsec时检测到解释器更改
