无法导入OrderedDict ImportError:无法导入名称“OrderedDict”

Question

我试着用allennlp做个回购。在运行它时，我无法在from typing import OrderedDict文件中导入ddp_accelerator.py。

Traceback (most recent call last):

ImportError: cannot import name 'OrderedDict'

我试着从collections或ordereddict导入它，就像我在其他帖子中看到的那样，但仍然无法理解。

我使用Python3.6

谢谢你帮我。

您必须使用Python3.6吗？Python3.7和更高版本的OrderedDict就在我们期望的地方。
