按照官方教程示例将模型以图形式保存后，部署至Triton服务中时出现异常。
程序：

import oneflow as flow
import oneflow.nn as nn
from flowvision.models.alexnet import alexnet


class MyGraph(nn.Graph):
    def __init__(self, model):
        super().__init__()
        self.model = model

    def build(self, *input):
        return self.model(*input)


if __name__ == "__main__":
    fake_image = flow.ones((1, 3, 256, 256))
    model = alexnet(pretrained=True, progress=True)
    model.eval()
    graph = MyGraph(model)
    out = graph(fake_image)

    MODEL_SAVE_DIR = "./alexnet"
    import os

    if not os.path.exists(MODEL_SAVE_DIR):
        os.makedirs(MODEL_SAVE_DIR)
    flow.save(graph, MODEL_SAVE_DIR)
