 ## 环境准备
 参考[环境准备](../../../README.md#环境准备)下载安装驱动/固件/CANN软件包   
-python 版本要求：python3.9   
+python 版本要求：python3.11 具体版本以dataflow wheel包编译时用的python版本为准，如果需要使用不同python版本，可以参考[py_dflow](../py_dflow)重新编译dataflow wheel包。
 sample_pytorch.py、sample_npu_model.py样例依赖pytorch和torchvision包,推荐使用torch 2.1.0和torchvision 0.16.0
