| 15 | +torch._C._host_emptyCache API consistency test. | ||
| 16 | + | ||
| 17 | +torch._C._host_emptyCache is an NPU-specific mirror created by | ||
| 18 | +torch_npu.contrib.transfer_to_npu, binding torch._C._host_emptyCache to the | ||
| 19 | +C++ implementation torch_npu._C._npu_hostEmptyCache. This file verifies both | ||
| 20 | +the mapping and its callable behavior so the API stays consistent across | ||
| 21 | +torch-npu releases. Additional torch._C._* consistency checks of the same kind | ||
| 22 | +can be appended here. | ||
