Я пытаюсь установить pip FFCV на Python 3.11/Windows 10, следуя инструкциям в разделе README для Windows. Изначально у меня были проблемы с обнаружением MSBuild, которые я решил и проверил с помощью образцов пакетов pip install без зависимостей. Теперь я получаю
DEPRECATION: Building 'ffcv' using the legacy setup.py bdist_wheel mechanism, which will be removed in a future version. pip 25.3 will enforce this behaviour change. A possible replacement is to use the standardized build interface by setting the `--use-pep517` option, (possibly combined with `--no-build-isolation`), or adding a `pyproject.toml` file to the source tree of 'ffcv'. Discussion can be found at https://github.com/pypa/pip/issues/6334
error: subprocess-exited-with-error
python setup.py bdist_wheel did not run successfully.
