+## 寒武纪平台运行方式
+
+**将上述运行脚本 `run_pytorch.py` 以及 `cuda_launch.py` 针对寒武纪平台做了相应的适配，具体见 `run_pytorch_mlu.py` 以及 `bang_launch.py`。**
+
+#### 1. 运行pytorch模型并生成输入和标准输出，可选择导出onnx
+
+使用 `--export_onnx` 设置导出onnx的目录，默认为当前路径 `./`，不使用这个flag则只进行计算和生成输入输出。
+
+```bash
+python run_pytorch_mlu.py --model gpt2  --batch_size 1  --length 1 --export_onnx ./
+```
+
+会在当前目录下生成输入输出文件`test_inputs.npy` 和 `test_results.npy`，目前只支持单一输入输出。
+
+#### 2. 运行InfiniTensor分布式脚本
+
+```bash
+python bang_launch.py --model "/XXX/XXX.onnx" --nproc_per_node 4 
+```
