| # ai.onnx.BitwiseXor |
|
|
| `ai.onnx` · standard ONNX operator · ONNX opset ≥ 18 |
|
|
| ## Description |
|
|
| Computes the elementwise bitwise `xor` of two integer tensors `A` and `B`, with NumPy-style multidirectional broadcasting. The output has the broadcast shape and the same dtype as the inputs. |
|
|
| See the [ONNX `BitwiseXor` spec](https://onnx.ai/onnx/operators/onnx__BitwiseXor.html) for the reference semantics. |
|

| | `a` | `A` | `T` | — | — | First input operand for the bitwise xor. | required | |
| | `b` | `B` | `T` | — | — | Second input operand for the bitwise xor. | required | |

|
| ## Use with `@huggingface/kernels` |
|
|
| ```sh |
| npm install --save-exact @huggingface/kernels@0.0.1-preview.2 |
| ``` |
|
|
| Required output shapes and logical data types are inferred from the supplied inputs and attributes; result tensors are allocated automatically. |
|
|
| The `version: 1` option selects the published kernel contract; it is independent of any operator opset, contrib `since_version`, or model version. |
| It follows the `v1` branch as fixes land. To pin exact artifact bytes, pass a 40-character commit `revision` instead of `version`. |
|
|
| Replace each `*Data` placeholder with a typed array containing the corresponding input data. |
|
|
| ```js |
| import { getKernel } from "@huggingface/kernels"; |
| |
| const kernel = await getKernel("webgpu-kernels/ai.onnx.BitwiseXor", { version: 1 }); |
| const { c } = await kernel({ a: { data: aData, shape: [3] }, b: { data: bData, shape: [3] } }); |
| ``` |
