* tests: revert change of torch_require_multi_gpu to be device agnostic The11c27dd33modified `torch_require_multi_gpu()` to be device agnostic instead of being CUDA specific. This broke some tests which are rightfully CUDA specific, such as: * `tests/trainer/test_trainer_distributed.py::TestTrainerDistributed` In the current Transformers tests architecture `require_torch_multi_accelerator()` should be used to mark multi-GPU tests agnostic to device. This change addresses the issue introduced by11c27dd33and reverts modification of `torch_require_multi_gpu()`.
