AssertionError: OKVQA requires 2 paths; one to questions and one to annotations

[Hao-YunDeng]

Hi, I am trying to run this notebook: https://github.com/facebookresearch/mmf/blob/notebooks/notebooks/kdd_tutorial.ipynb ,But I meet an error as follows. Can anybody tell me how to fix it?

Can you do me a favor? Thanks very much
