can't import OrderedDict ImportError: cannot import name 'OrderedDict'

Question

I'm trying to run a repo using allennlp. As I run it, I can't import from typing import OrderedDict in ddp_accelerator.py file.

Traceback (most recent call last):

ImportError: cannot import name 'OrderedDict'

I tried to import it from collections or ordereddict as I saw in other posts but still can't figure it out.

I'm using Python 3.6

Thanks for helping me.

Do you have to use Python 3.6? Python 3.7 and upwards have OrderedDict where we expect it.
