Question

我正在尝试部署一个称为transform_load的AWS lambda函数，该函数使用无服务器框架导入熊猫。我正在使用需求插件来压缩需求，以免遇到内存问题。

在测试功能时，出现以下错误。 python和numpy版本正确。需求是通过pip freeze从本地环境添加的。在serverless.yml中，添加了以下内容：

custom:
  .....
  # Zip the python requirements due to AWS lambda memory restrictions.
  pythonRequirements:
    zip: true
plugins:
  - serverless-python-requirements

话虽这么说，但我不确定在处理大型库（无论是AWS Lambda上的pandas还是scikit）方面有什么好的策略。

谢谢！

[ERROR] ImportError: Unable to import required dependencies:
numpy:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.7 from "/var/lang/bin/python3.7"
  * The NumPy version is: "1.18.5"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
