Generalized implementation of the Top K algorithm with sampling. Returns the sampled index from the innermost dimension of the input tensor for each row/subvolume.

Parameters:

dtype (DType): Data type of the input buffer.
out_idx_type (DType): Data type of the output indices.

Args:

max_k (Int): Largest number of top elements.
input (LayoutTensor): NDBuffer[dtype, rank] (Any shape)- The input tensor.
out_idxs (LayoutTensor): NDBuffer[out_idx_type, rank] (shape of [input_shape[:-1]] + [1]) - The output indices.
k (OptionalReg): Optional device buffer of top elements to keep for each batch element.
temperature (OptionalReg): The temperature based scaling.
top_p (OptionalReg): Only use the tokens whose cumulative probability exceeds this threshold.
seed (OptionalReg): The seed to use for the random number generator.
