@FrancoArtale hello! It looks like you've encountered a couple of issues during your validation process after converting to ONNX and OpenVINO formats.
-
ONNX Model Image Size Mismatch:
Your trace log indicates an image dimension mismatch during validation. When exporting the model using theexport.py
script to ONNX, you've defined the image size as 736x1280. However, during validation, you are attempting to use an image size of 1280x1280. Ensure the image dimensions match throughout the conversion and validation processes to resolve this. -
OpenVINO Model Validation Issue:
For the OpenVINO model, the error related to "NoneType
object is not subscriptable" typically points towards an issue with loading the class names or other essential data properties. Ensure that the configuration indata.yaml
is correctly loaded and accessible by the model during validation. Double-check the paths and formatting within yourdata.yaml
file.
If these tips don't resolve the issues, providing a more detailed error output or further context may help pinpoint the specific cause. Thanks for your detailed inquiry, and good luck with your further YOLOv5 deployments! 😊

- I'm using images of 1280x736, the images are okey:
The problem is in the command, I used --imgsz 1280 and i didn't add 736 because it's not possible. There is no --rect parameter in val.py, so it's not possible put --imgsz 736 1280.
If you see the next line from val.py, it's only accept one value:
parser.add_argument("--imgsz", "--img", "--img-size", type=int, default=640, help="inference size (pixels)")
- My data.yaml is:
#test: 100KBDD/test/images
train: 100KBDD/train/images
val: 100KBDD/valid/images
names:
0: 0
1: 1
2: 2
3: 3
4: 4
5: 5
6: 6
7: 7
nc: 8

It worked in other cases:
In training of the model.
In the validation of the original model.

Hey @FrancoArtale! Thanks for the additional details. 😊
-
Image Size in Validation: The
val.py
script indeed only accepts a single integer for--imgsz
, which sets both width and height to the same value. If your model was trained or exported with non-square dimensions (like 736x1280), you'll need to modify the validation script to accept two dimensions or adjust your model to work with square input sizes. This limitation inval.py
is by design to simplify the input size handling. -
Data.yaml Usage: It's great to hear that your
data.yaml
works well in other scenarios. If it's failing in specific cases (like with OpenVINO), the issue might be related to how the model or the validation script handles the loaded configuration. Ensure that the paths and format are consistently correct across different environments or setups.
For handling different aspect ratios during validation without modifying the script, consider resizing your images to square dimensions before validation as a workaround. Keep up the great work with YOLOv5! 🚀
