pypy3 support for daal4py/sklearnex

[lukezli]

Describe the bug
Hi all, thank you very much for such a great project! I am using pypy3 to speed up some python ML processes, but I'd like to use daal4py to speed up inference and it doesn't seem supported. Is there any way to patch it or to build from scratch to be compatible with pypy? Installing via python3 -m pip works fine.

To Reproduce
pypy3 -m pip install daal4py

import daal4py

Expected behavior
Should ideally work

Output/Screenshots

Environment:
Ubuntu 22.04, daal==2024.0.0

Support of pypy interpreter is not implemented currently.

Thanks for your response! Do you have any suggestions on how I can interface with daal4py via pypy3? Whether it be via writing some code to interface with the c library directly or something else? I tried creating a rpc interface from pypy to regular cpython but the overhead transmitting the data was too slow unfortunately.
