AttributeError: 'list' object has no attribute 'view' about yolov9 HOT 2 OPEN

Doing the work of @Youho99 here :)
Your issue looks the same as #315 or #302.
Probably you used a Yolov9 model with train.py. However, you need to use train_dual.py with a yolov9 model as train.py is only for Gelan models. Meaning you can either use a Gelan model with train.py as @Mecanight mentioned or use train_dual.py with the yolov9 model. (See #1)

I had a similar problem
But in my case it was:

Traceback (most recent call last):
  File "yolov9/segment/train.py", line 646, in <module>
    main(opt)
  File "yolov9/segment/train.py", line 542, in main
    train(opt.hyp, opt, device, callbacks)
  File "yolov9/segment/train.py", line 297, in train
    loss, loss_items = compute_loss(pred, targets.to(device), masks=masks.to(device).float())
  File "yolov9/utils/segment/loss_tal.py", line 173, in __call__
    batch_size, _, mask_h, mask_w = proto.shape
AttributeError: 'list' object has no attribute 'shape'

To fix this, I started using the models/segment/gelan-c-seg.yaml file instead of models/segment/yolov9-c-dseg.yaml

I don't think this is the solution for your case
But, I hope this helps
