Ошибка импорта Numpy в приложении mod_wsgi в Fedora 43 ⇐ Python

[Anonymous]

Я получаю сообщение об ошибке при импорте numpy из приложения Apache mod_wsgi в Fedora 43. Этого не происходит в Rocky Linux 9, рабочем сервере.
app.wsgi:
import sys
sys.path.insert(0, '/var/www/html/test/')
from test import application

test.py:
import numpy

def application(environ, start_response):
status = '200 OK'
output = b'Hello World!'

response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)

return [output]

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubles ... error.html

Please note and check the following:

* The Python version is: Python3.14 from "/var/www/html/test/venv/bin/python"
* The NumPy version is: "2.3.5"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Если я импортирую запросы, это работает. Файл конфигурации сайта Apache, настраивающий виртуальную среду:


ServerName test.local
ErrorLog logs/test-error_log
CustomLog logs/test-access_log combined

WSGIScriptAlias / /var/www/html/test/app.wsgi
WSGIDaemonProcess test processes=2 threads=15 display-name=%{GROUP} python-home=/var/www/html/test/venv
WSGIProcessGroup test


Require all granted




Когда я изменяю приведенную выше конфигурацию, чтобы не устанавливать переменную python-home, используя таким образом системную среду, ошибка меняется на

Импорт numpy как из venv, так и из системного (от имени root) интерпретатора командной строки работает
(venv) cpn@d3:/var/www/html/test$ python

Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy

Есть идеи?
Как предложил @Nick Odell:
(venv) cpn@d3:/var/www/html/test$ python -c 'import sys; print(sys.prefix)'
/var/www/html/test/venv
