Installing numpy on Mac to work on AWS Lambda

Update: the preferred approach now is to just use the AWS-provided Lambda Layer for NumPy/SciPy, which is super easy to do.

In the console, select your function and then, under the "Design" section click on "Layers". Then click "Add a Layer", and select "AWSLambda-Python37-SciPy1x" under AWS Provided (or whatever the equivalent is for the version of Python you're using).

Then you can seamlessly import numpy, scipy, etc. into your code with no issues.
