由于类空方法已具有docstring，导致内部服务器错误

Question

目前我面临一个问题。好的，让我分享一下。

我已经将这个项目部署到服务器（apache2）中，它工作正常，所有操作都成功。但是突然它在登录时基本上得到了内部服务器错误。当我下载日志时，它会显示RuntimeError：empty_like方法已经有一个docstring。当我再次重新启动我的服务器时，它再次顺利工作。但我认为这需要一个永久的解决方案。我也喜欢分享日志的完整跟踪。

Answer 1

我做了一些R

从文件中。

WSGIApplicationGroup指令可用于指定WSGI应用程序或WSGI应用程序集所属的应用程序组。同一应用程序组中的所有WSGI应用程序将在处理请求的进程的同一Python子解释器的上下文中执行。

在我看来，这似乎与单解释器=true有关。

并通过添加此行来配置mod_wsgi

WSGIApplicationGroup %{GLOBAL}

我观察了上一个月使用此配置的服务器日志。服务器运行时没有出现上述错误。
