AWS Lambda:"ELF load command address/offset not properly aligned" 通过无服务器框架部署时

AWS Lambda: "ELF load command address/offset not properly aligned" when deployed via Serverless Framework

我在 python3.6 中有一个使用以下包的 Lambda 函数:

opencv-python
imutils
numpy
joblib
mahotas
scikit-image
scikit-learn==0.22.1
sklearn
pymongo==3.10.1

我正在使用无服务器框架来最小化部署大小并部署到 lambda。我使用 serverless-python-requirements 插件来管理包。这是我的 template.yml 文件的样子:

functions:
  hello:
    handler: handler.hello

plugins:
  - serverless-python-requirements

custom:
  pythonRequirements:
    dockerizePip: non-linux
    zip: true
    slim: true
    noDeploy:
      - boto3
      - botocore
      - docutils
      - jmespath
      - pip
      - python-dateutil
      - s3transfer
      - setuptools
      - six
      - tensorboard
package:
  exclude:
    - node_modules/**
    - model/**
    - .vscode/**

我需要使用 slim & zip 选项,否则部署包会太大 (~350mb)。

出于某种原因,如果我不在 requirements.txt 中包含 pymongo,函数 运行 就可以了。不包含 pymongosls deploy 的输出是:

Serverless: Adding Python requirements helper...
Serverless: Generated requirements from /home/amman/Desktop/serverless-hello-world/requirements.txt in /home/amman/Desktop/serverless-hello-world/.serverless/requirements.txt...
Serverless: Using static cache of requirements found at /home/amman/.cache/serverless-python-requirements/3967fa669ece2345132bfe2a31be4287e2d61deedfb8b6006997a2192cea5753_slspyc ...

所以 .zip 的总大小约为 128 MB,函数 运行 没问题。但是,如果我包含 pymongosls deploy 的输出是:

Serverless: Adding Python requirements helper...

现在大小减少到 ~109 MB。大小不应该因为我添加了新的依赖项而增加吗?当我 运行 lambda 函数时,出现错误:

Unable to import module 'handler': /tmp/sls-py-req/cv2/cv2.cpython-36m-x86_64-linux-gnu.so: ELF load command address/offset not properly aligned

我认为这可能是一个无服务器框架问题。我能做些什么来解决这个问题?我试过安装不同版本的 pymongo 但没有成功。

我正在使用以下无服务器框架版本:

> serverless --version
Framework Core: 1.73.1
Plugin: 3.6.13
SDK: 2.3.1
Components: 2.31.2

编辑:有没有pymongo的替代品?我见过一些,但他们使用 pymongo 作为底层依赖。

我无法用无服务器解决这个问题。所以我决定 sls deploy 没有 pymongo 并且一旦无服务器生成了 .requirements.zip 文件,我将该文件复制到其他地方并再次 运行 sls deploy 但这次只有pymongo(和 pymongo[srv])在 requirements.txt。生成的 .requirements.zip 包含 pymongo 及其依赖项。我合并了这个 .requirments.zip 的文件和第一个 sls deploy 生成的 requirements.zip 的文件。通过这种方式,我在一个 .requirements.zip 文件中获得了所有其他依赖项(opencv2、numpy、joblib 等)和 pymongo。

之后,我压缩了源代码和合并的 .requirements.zip 文件,并手动 将 zip 上传到 s3。压缩后为 128MB。指示我的 lambda 函数使用来自 S3 的这个部署包并且它起作用了。我得到了 pymongo 以及 opencv2 和其他依赖项。

但是,缺点是您必须上传到 S3 并自行更新功能。在这个问题得到解决之前,我将不得不使用这个“hack”。

使用图层。 单独打包函数。
