1. 报错问题

In loss_tal.py: pred_distri, pred_scores = torch.cat([xi.view(feats[0].shape[0], self.no, -1) for xi in feats], 2).split(  
(self.reg_max * 4, self.nc), 1)  
The error is as follows：  
AttributeError: 'list' object has no attribute 'view'

2. 解决方法

2.1 修改yolov9.yaml文件 ：将检测头DualDDetect换成Detect

2.2 更换tain.py为train_dual.py 进行训练
