# tensorplay.library.get_kernel

Source: https://www.tensorplay.cn/docs/generated/tensorplay.library.get_kernel.html

```python
tensorplay.library.get_kernel(op: str | CustomOpDef, dispatch_key: str) → Callable[[...], Any]
```

dispatch_key accepts "cpu"/"cuda"/"default" and the
composite spellings.  Raises LookupError when nothing usable is
registered (a disabled concrete kernel counts as absent, matching
CustomOpDef.set_kernel_enabled() visibility).
