Some error in export to onnx

[Halafz7]

So I tried to train yolov5m-quant.yaml with coco128.yaml. When it's done, i want to export it but error come like this

Traceback (most recent call last):
File "/content/quantized-yolov5/models/experimental.py", line 97, in attempt_load
ema = ckpt['ema' if ckpt.get('ema') else 'model'].float()
KeyError: 'model'

During handling of the above exception, another exception occurred:

Do you have some advice or suggestion about this error? Thankyou

Hi @Halafz7,
Thank you for your interest. Can you share your command for exporting the model?

[Halafz7]

Sure, i ran it on Colab and saved the weights on my Gdrive

! python export.py --data coco128.yaml --weights /content/gdrive/MyDrive/models/CheckpointsYOLO/YOLOv5/yolov5medium/weights/last.pt --nodetect

[sefaburakokcu]

As the error states, you are trying to load weights from 80 classes into a model with only one class. However, your export arguments seem correct.

I think that attempt_load could not found your model.yaml. Can you replace last.pt with best.pt in your arguments?

[Halafz7]

Won't the classes switch automatically during training?

I did replaced the weight with best.pt but still got the same error
