OpenCV-python 不导入

Question

I am using Pydroid to code in android. Though it is an ARM machine so I downloaded OpenCV-python wheel from PiWheels and successfully installed it using pip. But i can't import OpenCV anyways. Please help.

Here is what I tried:

Answer 1

从 Windows 命令尝试安装- pip install opencv-python 然后导入 cv2 。

Answer 2

The name of the module is cv2.

Try import cv2 .

When I faced a similar problem in my laptop, installing opencv in a Conda environment did the job for me. Try removing opencv and try reinstalling it.

Answer 3

Don't take this as mean, but can you reply me the link to that particular wheel file? I am facing issues building wheels of opencv-python so it will be a great help

Answer 4

只需尝试检查您电脑的网络摄像头，如果它要求媒体功能包，请添加该功能并重试
