Description
I'm deploying an AWS Lambda Function to an edge device with IoT GreenGrass, when my function runs it has a problem with my import pandas requirement giving an error related to numpy.
See this thread on the AWS GreenGrass forums
Reproducing code example:
import pandas as pd(Numpy is a dependency of pandas)
I've written this using the AWS Toolkit for PyCharm, inside that there's a requirements.txt file listing numpy and pandas. The SAM build process has been set to complete in a container so as to avoid using numpy/pandas compiled for Windows.
Error message:
Here's the log file:

Numpy/Python version information:
Python 3.7
Numpy version unknown since I cannot import numpy to print its version.
It's quite possible this error is related to some proprietary gubbins Amazon is doing, between deploying it with SAM (Serverless Application Model) and then deploying it to an IoT device with IoT GreenGrass, perhaps some weird stuff has happened. I've created this issue so I can link to it in a bug report to Amazon.
