pdf2image is not trivially usable in AWS Lambda

[AndreaAdvanon]

Describe the bug
I'm trying to use this library in an AWS Lambda.

Exception: Unable to get page count. Is poppler installed and in PATH?

To Reproduce
Steps to reproduce the behavior:

1. Create a lambda in python that uses pdf2image
2. Run it

Expected behavior
Would be nice to have an official guide on how to make it work, as I'm still trying to figure out how to include it. I'm no python expert but I guess shipping the binary directly would be the best.

I must confess that I have little experience with AWS Lambda but I like the idea of having official documentation on how to deploy on cloud providers.

I have been working on another repository called pdf2image-as-a-service. While my current approach is to bundle the application in a docker container and deploy it on ECS (on AWS), I could add a how-to with AWS lambda.

In the meantime, if you figure it out please reply here as it could be used as a starting point for others.

@Belval unfortunately I didn't have enough time to sort this through so I ended up ditching AWS Lambda for this small project.

I would love to see support for Lambda though. If there were a straightforward way to use this library on Lambda I would move back to it.

Poppler is a dependency of pdf2image -- you'll have to install it and place it in your PATH (export PATH="$PATH:/path/to/poppler" or just install via Conda) before pdf2image will work.

[Belval]

Indeed, but have you succeeded in installing it? If you did I'd be very interested to read about it.

There is now an exhaustive example (with scripts to do it auto-magically) in https://github.com/Belval/pdf2image-as-a-service

If you have any problem with that example, feel free to open an issue on that repository.
