OpenCV with AWS Lambda

Question

I wrote a Lambda function (Python 2.7) that uses OpenCV. I need to import CV2 and I'm having trouble providing the library in my .zip. Has anyone used OpenCV with Lambda? How can I provide the CV2 module.

I'n trying to do the same at the moment. I was going to try with a static version of openCV but looks like I still have some shared dependencies while trying to run it on lambda. Did you get any luck in that? — Romanzo Criminale

I haven't had time to go through and test this, and saw @RomanzoCriminale's similar query on another question. Have you tried anything like this with EC2? markn.ca/2015/10/python-extension-modules-in-aws-lambda — Michael Wills

You must copy the OpenCV inside the zip that you send to AWS Lambda

This method helps to deploy with OpenCV https://github.com/aeddi/aws-lambda-python-opencv/blob/master/build.sh

If you're only dealing with cv2, I would suggest adding it as a layer - That way you can have access to opencv throughout all your lambda functions which have the same runtime.

I had to package both cv2 and scipy, where the package size was a huge problem, and I came to the following solutions in the end.

Using the serverless-python-requirements package on Serverless helped me streamline this whole process and reduce the package size as well. Would definitely recommend checking it out.

This is the guide that I followed

Serverless python-requirements plugin

Make sure to leave the strip flag to false to avoid stripping binaries which leads to the problem "ELF load command address/offset not properly aligned",

This is what my final serverless.yml came out to be which gave me the results I wanted to package sklearn + cv2 as a layer:

custom:
  pythonRequirements:
    dockerizePip: true
    useDownloadCache: true
    useStaticCache: false
    slim: true
    strip: false
    layer:
      name: ${self:provider.stage}-cv2-sklearn
      description: Python requirements lambda layer
      compatibleRuntimes:
        - python3.8
      allowedAccounts:
        - '*'

You would need to build your code in Amazon Linux environment.

You must to add cv2 like a Lambda Layer. Check this repo and do the following steps:

Clone the repo
Pick a version of opencv
Upload to a bucket
Create a Lambda Layer with the zip
Add the Layer to your Lambda.

it's all, enjoy it
