Using numpy in AWS Lambda

Question

I'm looking for a work around to use numpy in AWS lambda. I am not using EC2 just lambda for this so if anyone has a suggestion that'd be appreciated. Currently getting the error:

cannot import name 'multiarray'

Using grunt lambda to create the zip file and upload the function code. All the modules that I use are installed into a folder called python_modules inside the root of the lambda function which includes numpy using pip install and a requirements.txt file.

An easy way to make your lambda function support the numpy library for python 3.7:

1. Go to your lambda function page
2. Find the Layers section at the bottom of the page.
3. Click on Add a layer.
4. Choose AWS layers as layer source.
5. Select AWSLambda-Python37-Scipy1x as AWS layers.
6. Select 37 for version.
7. And finally click on Add.

Now your lambda function is ready to support numpy.
