问题描述：在添加了CBAM注意力机制后，运行train.py文件出现的错误：

RuntimeError: adaptive_max_pool2d_backward_cuda does not have a deterministic implementation, but you set 'torch.use_deterministic_algorithms(True)'. You can turn off determinism just for this operation, or you can use the 'warn_only=True' option, if that's acceptable for your application. You can also file an issue at https://github.com/pytorch/pytorch/issues to help us prioritize adding deterministic support for this operation.

解决方法：

查看error位置：

 在train.py文件中，大概324行左右，修改下列代码

# Backward
scaler.scale(loss).backward()

在原代码的基础上添加一行代码：

# Backward
torch.use_deterministic_algorithms(False) # 添加代码
scaler.scale(loss).backward()

重新运行 train.py 文件

修改成功！
