On my AWS account I created a Python 3.7 Lambda function
using a deployment package with NumPy library following the below steps [5]:
1) I launched an EC2 instance with Amazon Linux AMI which
is used by AWS Lambda Python 3.7 runtime [3]
2) I updated my instance with this command "sudo yum
update -y" and then installed Python 3.7 following the steps in this link
[6]:
$
python3 --version
Python
3.7.0
$
pip3 --version
pip
10.0.1 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)
3) Created a new directory
$
mkdir my_package_dir
$ cd
my_package_dir
4) Installed NumPy
$
pip3 install numpy -t .
#
Successfully installed numpy-1.16.4
5) My Lambda function handler is
$
nano lambda_function.py
import
numpy as np
def
lambda_handler(event, context):
a
= np.arange(15).reshape(3, 5)
6) Finally I created a zip file including the NumPy
library and my function's code in the handler file
$ zip
-r9 ../function.zip .
Then I used this "function.zip" file as my
deployment package in my Python 3.7 Lambda function and I confirm that it works
as expected. The above steps are also working with Python 3.6 which is included
in the yum repository and can be installed using this command "sudo yum
install -y python36", instead of pip3 you will use pip-3.6, all other
steps are the same.
