def make_node(type_key, **kwargs):
    """Make a new IR node by its type key and fields

    Parameters
    ----------
    type_key : str
        The type key of the node.

    **kwargs : dict
        The fields of the node.

    Returns
    -------
    node : Node
        The corresponding IR Node

    Note
    ----
    If the created node is instance of AttrsNode, then
    the creator function will also run bound checks and
    default value setup as supported by Attrs.

    Example
    -------
    The following code constructs a IntImm object

    .. code-block:: python

       x = tvm.ir.make_node("IntImm", dtype="int32", value=10)
       assert isinstance(x, tvm.tir.IntImm)
       assert x.value == 10
