升级pip并使用虚拟环境后仍遇openvino安装匹配错误

错误信息 #

#8 10.13 ERROR: Could not find a version that satisfies the requirement openvino>=2022.1.0 (from versions: none)

已尝试的解决方法 #

• 升级pip
• 使用虚拟环境安装
  以上方法均无效，设备为Macbook M1。

requirements.txt #

openvino>=2022.1.0; platform_system != "Darwin" or platform_machine != 'arm64'
openvino-arm; platform_system == "Darwin" and platform.machine == 'arm64'

build_docker.sh #

# Generates a base layer for the Lambda functions.

# Remove the container first (if it exists).
docker rm layer-container

# Build the base layer.
docker build -t base-layer .

# Rename it to layer-container.
docker run --name layer-container base-layer

# Copy the generated zip artifact so our CDK can use it.
docker cp layer-container:layer.zip . && echo "Created layer.zip with updated base layer."

问题原因 #

Macbook M1是arm64架构，默认构建的Docker镜像是arm64架构的Linux容器。此时容器内platform_system为Linux，platform_machine为aarch64（对应arm64）。

requirements.txt的第一个条件platform_system != "Darwin" or platform_machine != 'arm64'中，因为platform_system != "Darwin"为真，条件成立，pip会尝试安装openvino>=2022.1.0。但该版本的openvino没有提供arm64 Linux的预编译PyPI包，导致找不到匹配版本。

解决方案 #

方案1：调整requirements.txt的条件逻辑 #

明确区分不同架构的环境依赖，Linux arm64环境单独指定适配包（需确认包兼容性）：

# Linux x86_64 环境安装标准openvino
openvino>=2022.1.0; platform_system == "Linux" and platform_machine == "x86_64"
# Darwin arm64 环境安装openvino-arm
openvino-arm; platform_system == "Darwin" and platform_machine == "arm64"
# Linux arm64 环境安装适配版本（若openvino-arm支持则用，否则需源码编译）
openvino-arm; platform_system == "Linux" and platform_machine == "aarch64"

方案2：强制构建x86_64架构镜像 #

如果你的Lambda运行环境是x86_64，修改build_docker.sh的构建命令，指定架构：

docker build --platform linux/amd64 -t base-layer .

这样容器内是x86_64架构，pip能匹配到对应的openvino预编译包，即可正常安装。
