"""This operator sorts the input Blob at specified axis.
Args:
input (oneflow._oneflow_internal.BlobDesc): A Blob
axis (int, optional): dimension to be sorted. Defaults to the last dim (-1)
direction (str, optional): The direction in which to sort the Blob values. If the direction is "ASCENDING", The order of input will be sorted as ascending, else, the order of input will be sorted as descending. Defaults to "ASCENDING".
name (Optional[str], optional): The name for the operation. Defaults to None.
Returns:
