ValueError: zero-size array to reduction operation minimum which has no identity

AttributeError: ‘torch_npu._C._NPUDeviceProperties’ object has no attribute ‘multi_processor_count’

原因：torch_npu当前不支持DataParallel（DP）并行模式
解决办法：如果是运行单卡模式，在训练脚本中加入export ASCEND_RT_VISIBLE_DEVICES=0（指定 0 号卡对当前进程可见）。多卡环境模式需要运行DDP并行模式。
