AWS Lambda: How to use the pillow library?

Question

I am trying to create an AWS lambda function to sketch my uploaded images. My script works well locally, I followed this tutorial to deploy my function, but I have a problem with the Pillow library, really when I test my function. I see the following log:

I found this post with the same problem, but in my case I cannot execute the command line on the machine.

You must include libjpeg.so in your lambda package, but it will also require some configuration using the patchelf utility. Assuming you are preparing a lambda package through " pip install module-name -t " (and not through virtualenv ), follow these steps:

 cd into/your/local/lambda/package/dir cp -L $(ldd PIL/_imaging.so|grep libjpeg|awk '{print $3}') PIL/ patchelf --set-rpath PIL PIL/_imaging.so # zip, deploy and test the package 

This script works for Pillow version 3.2.0.

Regarding patchelf : under Ubuntu there may be 'apt install' ed, but under other Linuxes it may be necessary to build from the source .
