@Sambhu_Padmakumar I recommend reading the following:
If you don’t bother to read either of those, then you need to specifically read this excerpt:
The effort you put into describing your issue, situation, environment, research you’ve done, and what you’ve attempted so far, will directly correlate to the quality of the response you get.
That said, going to need you to clarify a few points:
I Labeled 144 images
How did you label these images? Are you using YOLOv8 via the python API to label them or are you using some type of annotation software?
when I exported it in YOLOv8 detection
What do you mean by “exported” and “detection” in this context? Normally, when people talk about “export” pertaining to YOLOv8, they mean exporting the model.
I only got 20 exported.
Only got 20 of what exported? 20 images? 20 labels? 20 instances? 20 classes?
I’m going to guess that you’re using some labeling/annotation software (CVAT, LabelStudio, Roboflow, etc.) and are attempting to save/export the annotations in the YOLO detection format to use for training. If that is the case, whatever software you’re using is who you need to get support from, not Ultralytics. Once you start training an Ultralytics YOLO model, that’s what this forum will provide support on.
