dataToGPU

  • dataToGPU(options?): GPUData

  • Copy the tensor's data to a new GPU resource. Comparing to the dataSync() and data(), this method prevents data from being downloaded to CPU.

    For WebGL backend, the data will be stored on a densely packed texture. This means that the texture will use the RGBA channels to store value.

    For WebGPU backend, the data will be stored on a buffer. There is no parameter, so can not use a user-defined size to create the buffer.

    Parameters

    • Optionaloptions: DataToGPUWebGLOption

    Returns GPUData

    For WebGL backend, a GPUData contains the new texture and its information. { tensorRef: The tensor that is associated with this texture, texture: WebGLTexture, texShape: [number, number] // [height, width] }

    For WebGPU backend, a GPUData contains the new buffer.
{
   tensorRef: The tensor that is associated with this buffer,
   buffer: GPUBuffer,
}

Remember to dispose the GPUData after it is used by
`res.tensorRef.dispose()`.
