ImportError

[lencshu]

"cannot import name 'DBManager' from 'DBManager' (/opt/python/DBManager/init.py)"

No matter how I change the yml, the err still exists, but openpyxl works well, any ideas?

here is part of my code:

serverless.yml

  name: aws
  runtime: python3.9
  stage: v15
  region: eu-west-3
  endpointType: REGIONAL

plugins:
  - serverless-python-requirements

Thx in advance,

pypi lists DBManager as python 3.6 and the runtime here is python 3.9
