MATLAB Error When Importing YOLOv8 Segmentation Model

[rsuchowitzki]

I encountered an error while trying to import a YOLOv8 segmentation model in MATLAB using the script provided in the repository. The error appears to be related to ONNX operators not being supported. Below is the detailed information about the setup and error:

Script:

net = importYOLOv8SegmentationModel('D:\semanticSegmentationTest\yolov8s_n.onnx');

Environment:

MATLAB version: 2024b
Operating System: Windows 11

Error Message:

Warning:
Unable to import some ONNX operators, because they are not supported. They have been replaced by placeholder layers or by placeholder functions inside generated custom layers. To find the placeholder layers, call the function
findPlaceholderLayers on the returned object.

2 operator(s)	:	Attribute 'atialias' is not supported.

To import the ONNX network as a function, use importONNXFunction.

The issue was caused by the importYOLOv8SegmentationModel function, but it has been resolved. Could you please uninstall and reinstall the Deep Learning Toolbox Converter for ONNX Model Format support package and try again?
