OpenCV-python不导入

Question

我正在使用Pydroid在android中编码。虽然它是一台ARM机器，所以我从PiWheels下载了OpenCV，并使用pip成功地安装了它。但无论如何我不能进口OpenCV。请帮帮忙。

以下是我尝试过的：

Answer 1

模块的名称是cv2。

试试import cv2。

当我的笔记本电脑遇到类似的问题时，在Conda环境中安装opencv完成了我的工作。尝试删除opencv并重新安装它。

Answer 2

从Windows命令行尝试安装：pip install opencv-python

然后是import cv2。
