I have tested the videos, and worked well, if your video frames have only one channel, you must modify the load code, have you solved your problem?

我已经测试过这些视频，并且效果很好，如果您的视频帧只有一个频道，则必须修改加载代码，是否已解决问题？

I don’t understand what you mean. Can you explain it in detail? Please forgive me if it disturbs you. I look forward to your reply. Thank you very much.

我不明白你的意思。你能详细解释一下吗？如果它打扰您了，请原谅我。我期待你的回复。非常感谢你。

你遇到什么问题了？

.hank you for your reply,The problem I am displaying may be caused by no camera, so I want to try to load the local video for identification。
The erro is 'NoneType' object has no attribute 'shape'.
The question may be very simple and basic, or even a little stupid, but I can get a reply. Thank you very much. If I delay your time, I hope to get your understanding, thank you very much

@LiuYeeJ It seems like that the video was failed to load. Make sure the path of the video file is correct.

@LiuYeeJ似乎无法加载视频。确保视频文件的路径正确。

Okay, thank you very much. I just picked up the camera and completed the recurrence of the experiment. Thank you very much for your help
