'tenseal._tenseal_cpp' Module Not Found

[DRKorossy]

Question

How do I fix a ModuleNotFoundError when trying to import tenseal?

Further Information

In a nutshell, I'm getting a ModuleNotFoundError for 'tenseal._tenseal_cpp' and I don't know how to start working with the tenseal library.

To elaborate, find the program that I'm trying to run and the full error message below:

Programme:
- name: fhe.py
- contents:
import tenseal as ts
print("hello, world")

[...path...]/venv/lib/python3.12/site-packages/tenseal/__init__.py", line 5, in
import _tenseal_cpp as _ts_cpp
ImportError: dlopen([...path...]/venv/lib/python3.12/site-packages/_tenseal_cpp.cpython-312-darwin.so, 0x0002): tried: '[...path...]/venv/lib/python3.12/site-packages/_tenseal_cpp.cpython-312-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64h' or 'x86_64')), '/System/Volumes/Preboot/Cryptexes/OS/Users/[...path...]/venv/lib/python3.12/site-packages/_tenseal_cpp.cpython-312-darwin.so' (no such file), '[...path...]/venv/lib/python3.12/site-packages/_tenseal_cpp.cpython-312-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64h' or 'x86_64'))

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "[...path...]/fhe.py", line 1, in

File "[...path...]/venv/lib/python3.12/site-packages/tenseal/__init__.py", line 7, in
import tenseal._tenseal_cpp as _ts_cpp
ModuleNotFoundError: No module named 'tenseal._tenseal_cpp'

System Information

• OS: iOS (13 inch MacBook Pro 2020)
• CPU: 2 GHz Quad-Core Intel Core i5 (2020 model, before the M1 chips were introduced)
• OS Version: Sonoma
• Language Version: Python 3.12
• Package Manager Version: pip

Additional Context

The error message mentions "have 'arm64', need 'x86_64h' or 'x86_64'". However, when checking using: uname -m
I get: x86_64. So I don't have arm64. My guess is that either the programme is unable to identify the x86_64 as it is, or there are missing files from the library.

I'd appreciate any and all support, thanks.
