IntImm: require field span

x = tvm.ir.make_node?

Signature: tvm.ir.make_node(type_key, **kwargs)
Docstring:
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
File:      /media/pc/data/lxw/ai/tvm/xinetzone/__pypackages__/3.10/lib/tvm/ir/attrs.py
Type:      function
