 ### Training
-NPU startup script samples have been added for each type of model,the scripts are stored in the `examples/xxx/special/npu_scripts`, for example `examples/wanvideo/model_training/special/npu_scripts/Wan2.2-T2V-A14B-NPU.sh`.

 In the NPU training scripts, NPU specific environment variables that can optimize performance have been added, and relevant parameters have been enabled for specific models.

 ### 训练
-当前已为每类模型添加NPU的启动脚本样例，脚本存放在`examples/xxx/special/npu_scripts`目录下，例如 `examples/wanvideo/model_training/special/npu_scripts/Wan2.2-T2V-A14B-NPU.sh`。

 在NPU训练脚本中，添加了可以优化性能的NPU特有环境变量，并针对特定模型开启了相关参数。
