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.
KLayoutType (TensorLayout): Layout type of the k buffer.
TemperatureLayoutType (TensorLayout): Layout type of the temperature buffer.
TopPLayoutType (TensorLayout): Layout type of the top_p buffer.
SeedLayoutType (TensorLayout): Layout type of the seed buffer.

Args:

max_k (Int): Largest number of top elements.
input (TileTensor[dtype, address_space=input.address_space, linear_idx_type=input.linear_idx_type, element_size=input.element_size]): TileTensor[dtype] (Any shape)- The input tensor.
out_idxs (TileTensor[out_idx_type, address_space=out_idxs.address_space, linear_idx_type=out_idxs.linear_idx_type, element_size=out_idxs.element_size]): TileTensor[out_idx_type] (shape of [input_shape[:-1]] + [1]) - The output indices.
k (Optional[TileTensor[DType.int64, KLayoutType, ImmutAnyOrigin]]): Optional device buffer of top elements to keep for each batch element.
temperature (Optional[TileTensor[DType.float32, TemperatureLayoutType, ImmutAnyOrigin]]): The temperature based scaling.
top_p (Optional[TileTensor[DType.float32, TopPLayoutType, ImmutAnyOrigin]]): Only use the tokens whose cumulative probability exceeds this threshold.
seed (Optional[TileTensor[DType.uint64, SeedLayoutType, ImmutAnyOrigin]]): The seed to use for the random number generator.
