Yolov5 quantized model mAP 0 issue

[MuhammadBabarAli]

I am using Vitis-AI 3.5 to deploy a yolov5 model, I found this tutoiral for quantization: https://www.hackster.io/LogicTronix/yolov5-quantization-compilation-with-vitis-ai-3-0-for-kria-7b005d

When I use the yolov5 val.py file to evaluate the model before quantization I get mAP 0 when I use the .pt model and I get the correct mAP using the .onnx and .torchscript formats(screenshots attached).

I got the quantization script from this tutorial and i tried to quantize the model and got this error

I also tried to quantize another model and it successfully quantized but when i evaluate it using val.py with the .pt format i get an error and with the .onnx format i get mAP 0

Please guide me how can I evaluate the mAP of the quantized model and how to fix this error. Thanks
