[Question] How to host on AWS Lambda?

[Danoctum]

Currently trying to host this ono AWS Lambda.

Steps I've done:

1. Clone image from dockerhub and push to private ECS repository
2. Create Lambda from Docker container on architecture x86_64 and expose port 5000
3. Added NUMBA_CACHE_DIR environment variable with value /tmp

After doing this configuration and running the Lambda, I get the following error:

/usr/local/lib/python3.9/dist-packages/numba/np/ufunc/parallel.py:323: UserWarning: Could not obtain multiprocessing lock due to OS level error: [Errno 38] Function not implemented

According to my research, this is because Lambda's can not run on multiple cores in Python (even when raising Lambda RAM to > 1769MB). A fix could be to downgrade to Python 3.7, but that would mean getting an older version of this library.

I've tried to search the source code for usage of Multiprocessing.Pools, which could be replaced by Multiprocessing.Queue as a fix, but I think that's in a library that rembg makes use of.

Does anyone have an idea how to fix this?
