Cython modules are missing on the arm64 architecture

[yurivict]

import GPy prints these messages:

I've altered one of them to include the exception.

GPy was installed using pip that worked off of the requirements.txt file.

The same process installs GPy on the x86_64 without such problem.

The problem is caused by missing cython modules in the wheel on the PYPI website, for example only x86_64 cython module is present for choleskies_cython:

$ find .  | grep chol
./util/choleskies_cython.cpython-311-x86_64-linux-gnu.so
./util/choleskies_cython.c
./util/choleskies.py
./util/choleskies_cython.pyx

OS: Linux on the aarch64 machine
