Pull request overview
This PR refactors device handling by introducing a unified DeviceManager abstraction and updating existing utilities to use it, with the intent of reducing scattered backend-specific (cuda/xpu/hpu) branching across the codebase.
Changes:
- Added
auto_round/utils/device_manager.pyto centralize backend discovery and runtime ops (sync/cache/memory queries). - Updated
auto_round/utils/device.pyto route device counting, selection, memory clearing, and memory queries through the new device manager APIs. - Updated
auto_round/auto_scheme/delta_loss.pyto synchronize via the active device manager and broaden “non-CPU device” checks.
