WasmGPU.python.toCPU

Summary

WasmGPU.python.toCPU copies a validated Python buffer into a new owning CPUndarray. The returned ndarray has the source dtype and shape and remains valid after the Python buffer proxy is released.

Syntax

WasmGPU.python.toCPU(src: PythonArraySource): CPUndarray
const array = wgpu.python.toCPU(src);

Parameters

Name	Type	Required	Description
src	PythonArraySource	Yes	C-contiguous Python buffer or proxy exposing getBuffer().

Returns

CPUndarray - New owning CPU ndarray containing a copy of the source data.

Type Details

type PythonArraySource = PyProxyLike | PyBufferLike;

The source must be C-contiguous and use i8, u8, i16, u16, i32, u32, f32, or f64. Shape, strides, offset, item size, and byte range are validated before allocation. A buffer acquired through getBuffer() is released even when validation or copying fails.

Example

const array = wgpu.python.toCPU(pythonArray);
console.log(array.dtype, array.shape, array.data());
