| # ai.onnx.And |
|
|
| `ai.onnx` · standard ONNX operator · ONNX opset ≥ 7 |
|
|
| ## Description |
|
|
| Computes the elementwise logical `and` of two boolean tensors `A` and `B`, writing the result to `C`. Supports multidirectional (NumPy-style) broadcasting. |
|
|
| See the [ONNX `And` spec](https://onnx.ai/onnx/operators/onnx__And.html) for the reference semantics. |

| ## Use with `@huggingface/kernels` |
|
|
| ```sh |
| npm install --save-exact @huggingface/kernels@0.0.1-preview.3 |
| ``` |
|
|
| 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. |
|
|
| A `bool` input takes 0/1 values in a `Uint8Array` together with `dtype: "bool"`, since no typed-array class implies it. |
|
|
| ```js |
| import { getKernel } from "@huggingface/kernels"; |
| |
| const kernel = await getKernel("webgpu-kernels/ai.onnx.And", { version: 1 }); |
| const { c } = await kernel({ |
| a: { data: aData, shape: [4], dtype: "bool" }, |
| b: { data: bData, shape: [4], dtype: "bool" }, |
| }); |
| ``` |
