How to use gin-config with data types and namedtuples?

[RylanSchaeffer]

I'm using a codebase that uses gin-config and one function argument I want to modify is a list consisting of tuples (str array name, array shape, array data type). How does one specify a data type using gin-config?

Ok this just became a little more complicated. The function doesn't accept a list of tuples - it requires a list of named tuples. How can I specify these with gin-config?

You can define a NamedTuple and register with gin and then use it configure other functions.

import typing
from typing import List
import gin

@gin.register
MyTuple(typing.NamedTuple):
  arg1: int
  arg2: str

@gin.register
def function(configs: List[MyTuple])
   ...

And the configure MyTuple

# Gin file

A/MyTuple.arg1 = 23
A/MyType.arg2 = 'A'

B/MyTuple.arg1 = 12
B/MyType.arg2 = 'B'


function.configs = [@A/MyTuple() @B/MyTuple()]
