如何在python主机cpanel上使用OpenCV库？

Question

我有一个django项目，我需要在其中使用OpenCV库。只要我在计算机上的本地主机上运行项目，我就没有错误或问题。然而，当我在互联网上的真实主机（主机使用Linux作为操作系统）上推动我的项目时，我会遇到一些我无法解决的错误。在第一级，当Iimport cv2（我已经安装了numpy lib）时会显示此错误：

因此，我假设我没有import numpy.core.multiarray是问题所在，但当我这样做时，新的错误出现了：

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

Please note and check the following:

  * The Python version is: Python3.5 from "/home/camsclou/virtualenv/IP_Camera/3.5/bin/python3.5_bin"
  * The NumPy version is: "1.18.5"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: PyCapsule_Import could not import module "datetime"

我已经在互联网上搜索了这个问题，我也查了错误页面，但我什么也没有得到。我应该如何在项目中使用此库
