   1. 使用graph模式导出mlir模型
 
-     ```python
-     class MyGraph(nn.Graph):
-         def __init__(self, model):
-             super().__init__()
-             self.model = model

-         def build(self, *input):
-             return self.model(*input)
-     
-     model = Resnet50Module()
-     model.eval()
-     graph = MyGraph(model)
-     flow.save(graph, "./resnet50_model/")

+            outs = graph(input)
+            flow.save(graph, "./esnet50_model/")

   2. 使用`oneflow-lite-compile`工具将模型编译成`oneflow-lite`的模型文件格式（以华为Ascend NPU为例）
