containers - set .cache dir for python libraries

[qaixerabbas]

I am working on a voice transcription project and using AWS Lambda for deployment. I am trying to run a voice transcription model in AWS Lambda. I am using few third party libraries that use their cache dir but in Lambda that path is read only.

How can I set a single cache dir for all the possible libraries so I can use Lambda's /tmp for storing cache. I do not want to set path for each library I want to set a single cache dir for all libraries. How can I do this? I know I can use following two methods for individual libraries for setting cache directories.

in Docker file:

ENV LIBRARY_CACHE_DIR /tmp/library_cache

In Python Code:
os.environ['LIBRARY_CACHE_DIR'] = '/tmp/library_cache'

Issue with this approach is that I do not know in advance what libraries are required by my current third party libraries. If I have 1 or 2 libraries I can set their cache dir easily. But I am facing issues with multiple libraries. I have to set path for each library and test on Lambda. So I was thinking is there any way so that all the libraries cache dir is set via single command?
