How to reduce the size of packaged python zip files for AWS Lambda

Question

Afternoon,

I recently came across AWS Lambda and Azure Functions. AWS imposes a limit on the size of zipped as well as unzipped files, which for python scripts need to include all of the dependent modules. I have been using lambda-uploader to package my script and it's module dependencies, but the pandas package is too big.

I have seen examples of people completing machine learning and using pandas on AWS Lambda (a little outdated though) but I can't see how they're doing it. Any suggestions?

If you're using Python libraries, you can get rid of botocore, boto3 as they are already present in AWS's lambdas functions.
