This has driven me absolutley crazy - I know there are a few similar questions on here with a similar scenario - but I have tried mutliple solutions and nothing works - so I thought I'd request help myself and give full context. I am building a very simple process in AWS: upload image into bucket, lambda picks it up, processes it, dumps it in other bucket. Everything is set up, terraform, python code etc - however whenever the lambda is invoked, I always get the error: [ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function': cannot import name '_imaging' from 'PIL' (/var/task/PIL/__init__.py) Some important things to note: I am dev'ing on Windows (never doing this ever again!!!) I have tried multiple Python runtime versions (Python 3.13, Python 3.12, Python 3.10, Python 3.9 Lambda architecture is x86_64 My python code simply has the following line at the top of the file, which is what is causing me this problem: from PIL import Image What I have tried: Switching Python runtimes of course Creating a package folder, installing Pillow here, and then zipping up with my Lambda python code Using Lambda layers (which seems like the most popular, easiest and quickest solution) by grabbing my relevant arn arn:aws:lambda:eu-west-2:770693421928:layer:Klayers-p39-pillow:1 Using docker to run an amazon linux container (docker run -it --rm -v ${PWD}:/app --workdir /app amazonlinux:2 bash), creating a package folder, installing the Pillow dependencies, and then zipping up with my python code No matter what, I always get the error mentioned above. Something else to mention is that this was only supposed to be a simple small project which would take an evening or two, so ideally I don't want a huge solution that reinvents the wheel or involves a lot more development (unless that is the only solution at this point). If someone is able to replicate my situation, and somehow work out a solution then I would be hugely appretiative. As a matter of fact, if someone is able to replicate my situation and also run into the same problem, I'd be very appretaitive as at least I would know I am not going crazy. Thanks all.
