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):

    from typing import (
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.

  • Did you also install `allennlp-models`? I recently faced a similar problem; uninstalled both, and then reinstalled allennlp (actually, all the `pip` requirements). The problem was perhaps due to different versions: `allennlp-models 2.7.0 requires allennlp<2.8,>=2.7.0, but you have allennlp 2.4.0 which is incompatible.` – Barun May 26 '22 at 05:48

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