  训练出现长警告
  ```
  I0706 13:09:13.075042 3772 eager_method.cc:140] Warning:: 0D Tensor cannot be used as 'Tensor.numpy()[0]' . In order to avoid this problem, 0D Tensor will be changed to 1D numpy currently, but it's not correct and will be removed in release 2.6. For Tensor contain only one element, Please modify 'Tensor.numpy()[0]' to 'float(Tensor)' as soon as possible, otherwise 'Tensor.numpy()[0]' will raise error in release 2.6.

  ### 复现环境 Environment
  
  PaddleDetection2.6
  PaddlePaddle2.5.0
  
  经过排查将`ppdet/utils/stats.py`第77行进行如下修改
  `v.update(stats[k].numpy())`→`v.update(float(stats[k]))`
  
  ### Bug描述确认 Bug description confirmation
  
  - [X] 我确认已经提供了Bug复现步骤、代码改动说明、以及环境信息，确认问题是可以复现的。I confirm that the bug replication steps, code change instructions, and environment information have been provided, and the problem can be reproduced.
