Can't load yolov8x.mat

[ESSNIA]

Hello,

After I cloned the repo on my local disk, and added the 'models' subdirectory to my path I tried down/loading YOLOv8x like below:

modelName = 'yolov8x';
data = helper.downloadPretrainedYOLOv8(modelName);
det = data.yolov8Net;

The model downloads (seemingly) correctly as I get the 'Done. ' message. Then I get the following warnings and it results in the network not loading (empty values).

Warning: Unable to load instances of class nnet.onnx.layer.VerifyBatchSizeLayer into a heterogeneous array. The definition of
nnet.onnx.layer.VerifyBatchSizeLayer could be missing or contain an error. Default objects will be substituted.

                        privateNet = deep.internal.network.EditableNetwork(in.LayerGraph);
Error in helper.downloadPretrainedYOLOv8 (line 23)
model = load(netMatFileFullPath); 
> In helper.downloadPretrainedYOLOv8 (line 23) 

I tried downloading it directly through my web browser with the same result. I can't confirm if it is a possible corrupted download as there are no hashes (MD5 / SHA256) available AFAIK.

Doing the same works fine with all other model variants (nano, small, medium and large)

Any help would be appreciated.

As mentioned in the requirements, can you please ensure "Deep Learning Toolbox Converter for ONNX Model Format" support package is installed?

Thanks for your reply.

Indeed, always check the requirements first !

Thought I had it installed... I had not.

Works now!
