CI tests verify correct operation of YOLOv5 training (train.py), validation (val.py), inference (detect.py) and export (export.py) on MacOS, Windows, and Ubuntu every 24 hours and on every commit. |
@lkno0705 we don't assist in debugging custom code, but you can start from the official usage example shown in val.py. If you encounter any reproducible errors following the official usage example please let us know! Lines 5 to 18 in 5f97001

@glenn-jocher That's understandable. However, the problem also occurs when using the example command in val.py:

@lkno0705 thanks for the update! It looks like you are passing incompatible combination of |
@glenn-jocher Yeiks, that mistake was so dumb.. Thanks for the hint! It works now... It makes sense that if you select the correct model to validate, that then the prediction classes are matching and then no index error while validating occurs... Thanks a lot! It seems like I've looked at my screen for too long today! Have a great day! |
Improved error messages for understanding of user error with val.py. May help #7291

Bug
I currently have the problem that, if I train a yolo model on a custom dataset, everything works as expected, the model is saved, results get plotted and synced to wandb. But as soon as I try to run the validation seperately with val.py it fails with an index error:
For reference:
the dataset yml:
I'm calling val.py in a python file as follows:
The prepared dataset looks as follows:
with the following structure in every label text file:
4 0.6889705882352941 0.5975 0.01764705882352935 0.030000000000000027
if there are multiple objects in the image, then the next object annotation is written to the next line:
The train split includes 720 images, the val and test split include 120 images. I checked all annotations, as this was my first guess but all their classes are correct.
