failure on macos M1 when JVM and python architecture do not match

I tried out libpython-clj and was facing the following error message:

"Execution error at libpython-clj2.python/initialize! (python.clj:87).
Failed to find a valid python library!"

The cause of this error was that I was using JVM for x86_64 via Rosetta and python was referencing to a native arm64.
After using a arm64 JVM it worked.
It took me quite some time to figure this out.

I think it would be helpful to mention in the docs that the architecture of python and jvm must match.
Further we could check this requirement during the initialize! function and return a proper error message.
This would improve user experience.
In the JVM we can check the architecture with:

(System/getProperty "os.arch")
This gives aarch64 or x86_64.
In python we can check the architecture with:

import platform
platform.machine()

on M1 this returns 'arm64'.

Commencez par libpython-clj2/python.clj:87 et la fonction initialize!, puis localisez la documentation pertinente concernant les exigences de configuration et d’architecture. Confirmez comment les architectures de JVM et Python sont obtenues, documentez l’exigence de correspondance et assurez-vous que l’initialisation signale clairement une erreur lorsqu’elles diffèrent.
