successfully run everything but saved images and videos don't have any bounding boxes and confidence. can you help me with this?

[@TheCodingBug]

You might've missed something. Check pytorch version also. Because it's not possible to have empty bounding boxes from pretrained model.

[@tanasakchiewchankul9739]

I have same problem with you. 😢

[@wei-yenchen7610]

I have the same problem . My gpu is 1650ti 4G (laptop : G14) I don't konw the reason that the result don't have any bounding boxes and confidence. TheCodingBug is right. Only run on CPU , the problem is solved. add those code to the file named "detect.py" ↓↓↓ torch.cuda.is_available = lambda : False device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')

Hello. Congratulations on the video. I couldn't find the images and videos you used in the example. Could you tell me how to get it? Thank you for your attention. Thanks!

[@TheCodingBug]

The link is in the description of the video.

[@ShlomoOrna]

Very helpful video. Thank you. Could you add some explanation on how to run YOLOv7 POSE Estimation ? In a response or does it need a separate video ?

[@aashishmalhotra]

discovered your channel today , and so far content is good. what to expect in future. Will we be doing any projects in yolo?

[@TheCodingBug]

Thanks for the appreciation. Yes. I am working on couple of projects with YOLOv7. Stay tuned!!

[@miloszivkovic6118]

Very easy and I made it. But my cpu was dying 😂 , i followed evry step and is it possible that yolo is still using my CPU?

[@dwnim]

thank you for the tutorial, help me alot. i'm newbie in this python environment. i have run the script with webcam and it worked. the problem is, i dont know how to end the webcam process. could you please help me of how to stop the process ? thanks in advance

[@TheCodingBug]

Press q or ESC. Otherwise, end script with cntrl+c

[@fatguyinalittlevive1107]

Thanks for the easy to follow tutorial! Do you have a tutorial for training your own YOLO v7 model?

[@TheCodingBug]

Yes. Following is for training on local machine. You can also find training with colab on my channel. kzbin.info/www/bejne/Y4K6qX1mn554j5o

[@MdFaiyazAhmedRME]

Thanks for this video. I have the same problem like others but i want clarify one thing. Do in need to use only pre trained images or i can simply download any image and use it. in my case No bounding box or score

[@TheCodingBug]

You can use any image. Try horse image that is included with the repository

@TheCodingBug thank so much for this video i take the combination of knifes and guns dataset after training it detects knife as an airplane but i didn't use label called airplane plz could you help me

[@TheCodingBug]

Change labels in text file before training as shown here kzbin.info/www/bejne/Y4K6qX1mn554j5o Or just don't load labels from model and redefine them as per your requirements (i. e. replace labels variable with your own)

[@VasiliiSilvestrov]

Thank you very mush! Very helpful video! I want to share with the auditory a couple things: firstly: instead of downloading you can you git clone command. It will save lots of time: you won't need to extract and copy files. And secondly, сould you add the used pictures and videos in the description, please.

[@TheCodingBug]

That's without cuda support. That's why I install it separately with cuda.
