Converting Yolov5 failed with weird errors

[HenryFuhengWu]

I was trying to convert a YOLOv5 model from onnx to OV IR but got the error as below:

This original model is from official Yolov5 repo. Anyone can help? Thanks.

Hi Henry,

Thanks for reaching out to us.

For your information, YOLOv5 is currently not an officially supported topology by the OpenVINO toolkit.

However, I would like to share with you about this tutorial.

https://github.com/violet17/yolov5_demo.

Identify the output nodes of your model with Netron and specify them in the Model Optimizer.

For example:

python mo_onnx.py --input_model yolov5m.onnx -s 255 --reverse_input_channels --output Conv_322,Conv_375,Conv_428

Regards,

Peh

Thanks for the reply, Peh. I don't understand why the YOLOV5 is not supported. I feel it may be impossible to enumerate all the models in the world and add support to them one by one... Say if I have my own model called XYZ, how do I know if OpenVino supports it or not? Can you share me the root cause of not supporting it? Is it because of some technical challenges or some IR design limitation, or even hardware issue or whatever? Sorry for trying to dig deep. Thanks a lot.

Hi Henry,

Yolo v5 was stated not officially supported by the OpenVINO toolkit because it yet to validated by Developer teams and hence include the model in the Public Pre-trained Models.

To ensure a model can be supported by OpenVINO toolkit, you can check whether the model is one of the supported topologies and its framework layer is supported in Supported Framework Layers. If one of the layers in the model is not in the supported framework layers list, the Model Optimizer might unable to recognize that layer and hence fails when converting into Intermediate Representation (IR).
