cannot connect to X server

[6Lackiu]

Hello, when I run "!python object_tracker.py --video ./data/video/cars.mp4 --output ./outputs/tracker.avi --model yolov4" on colab, it prompts "cannot connect to X server", what is the reason and how to solve it?
Looking forward to your reply, thank you!

Use the --dont_show flag:

!python object_tracker.py --video ./data/video/cars.mp4 --output ./outputs/tracker.avi --model yolov4 --dont_show

Use the --dont_show flag:

!python object_tracker.py --video ./data/video/cars.mp4 --output ./outputs/tracker.avi --model yolov4 --dont_show

Thank you for your answer, but if I operate as you did, my output video is not tested and is the same as the original video. I don't know why.

使用--dont_show标志：
!python object_tracker.py --video ./data/video/cars.mp4 --output ./outputs/tracker.avi --model yolov4 --dont_show

感谢您的回答，但是如果我按您的方式操作，我的输出视频将未经测试，并且与原始视频相同。我不知道为什么

The problem is solved, thank you!

Hi @6Lackiu , I have the same problem. I use the --dont_show flag, and my output video is the same as original.
Have you been able to solve it? Thanks in advance.

@rebeccamart I'd love to help you out, but unfortunately it's been a long time since I worked on this project and I can't remember the details. Maybe you can ask someone else. Feel sorry!
