ImportError: cannot import name 'backward_compatible_config' from 'config'

[kakaaaaa4]

Hello！Thank you for sharing your work!
But I have the following issue when running the code:
ImportError: cannot import name 'backward_compatible_config' from 'config'.
I tried to use "pip install config" but it was not solved.
How to solve the problem?

Besides, I really want to know how to train my own model.

The problem arises when i use command "sh inference.sh"
