Python: numpy: 检测到解释器更改 - 每个进程只能将此模块加载到一个解释器中

Question

我在 Ubuntu 18.04 上有一个 Flask 应用程序运行，Apache 服务器，反应前端，Flask (selenium) 后端。

我的应用程序运行良好，但有时我会在多台服务器上收到以下消息：

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

完整的错误日志：

我不知道发生了什么或我应该改变什么。我读了一些关于更新 ini 文件以使用单一解释器的内容。

single-interpreter = true

但是我不确定这是否适用于我的应用程序，因为我使用的是 wsgi 而这是针对 uswgi 的？

Answer 1

尝试在您的 .conf 文件中添加 WSGIApplicationGroup %{GLOBAL}。（在我的例子中是“nano /etc/apache2/sites-available/FlaskApp.conf”）

python

apache

numpy
