使用apache和mod_wsgi在django中使用scipy

I have defined a django view that uses scipy.optimize.curve_fit. This works without problems using the django development server, but when I deploy the Django application with Apache and mod_wsgi the view function gets stuck importing curve_fit:

我已经定义了一个使用scipy.optimize.curve_fit的django视图。使用django开发服务器时这没有问题，但是当我使用Apache和mod_wsgi部署Django应用程序时，视图函数会导致导入curve_fit：

from scipy.optimize import curve_fit

When this line is removed the rest of the app works well on the Apache server. Why does this line not work with Apache and mod_wsgi?

删除此行后，应用程序的其余部分在Apache服务器上运行良好。为什么这行不适用于Apache和mod_wsgi？

In your WSGI file you will have something that looks like this:

在您的WSGI文件中，您将看到如下所示的内容：

<VirtualHost>
    ...
    WSGIScriptAlias / /somepath/deployment/wsgi/yoursite.wsgi
</VirtualHost>

You need to add the following line:

您需要添加以下行：

<VirtualHost>
    ...
    WSGIScriptAlias / /somepath/deployment/wsgi/yoursite.wsgi
    WSGIApplicationGroup %{GLOBAL}
</VirtualHost>
