【以下的问题经过翻译处理】 我试图通过扩展预构建镜像来部署SageMaker推理端点。然而，它失败了，错误为“FileNotFoundError：[Errno 2] No such file or directory: 'serve'”。

我的Dockerfile：

ARG REGION=us-west-2

SageMaker PyTorch image

FROM 763104351884.dkr.ecr.$REGION.amazonaws.com/pytorch-inference:1.12.1-gpu-py38-cu116-ubuntu20.04-ec2

RUN apt-get update

ENV PATH="/opt/ml/code:${PATH}"

#此环境变量用于SageMaker PyTorch容器确定我们的用户代码目录。 ENV SAGEMAKER_SUBMIT_DIRECTORY /opt/ml/code

＃/ opt / ml及其所有子目录由SageMaker使用，使用/code子目录存储用户代码。 COPY inference.py /opt/ml/code/inference.py

#将inference.py定义为脚本入口点 ENV SAGEMAKER_PROGRAM inference.py
