System Info

Building accelerate 1.12.0 on Python 3.14

Information

• The official example scripts
• My own modified scripts

Tasks

• One of the scripts in the examples/ folder of Accelerate or an officially supported no_trainer script in the examples folder of the transformers repo (such as run_no_trainer_glue.py)
• My own task or dataset (give details below)

Reproduction

1. Build on Python 3.14 on x86_64-linux.
2. Observe the following test failures:

FAILED tests/test_cli.py::AccelerateLauncherTester::test_accelerate_test - RuntimeError: There is no current event loop in thread 'MainThread'.
FAILED tests/test_cpu.py::MultiCPUTester::test_cpu - torch.multiprocessing.spawn.ProcessRaisedException: 

W0105 19:35:39.943000 597 torch/multiprocessing/spawn.py:174] Terminating process 620 via signal SIGTERM

Expected behavior

It should build and test cleanly.
