video branch's problem

[SophieZhou]

I generate the data following readme, but when I run the test.py, the data can not be used. And the error informations as follows.

The error occured here

I check the data, it is a dict not a list.
But I follow the readme to generate the data in video branch. Maybe any mistakes I missed.

Sorry, it could related to dataset or package versions, and I cannot think of any specific reason for this. Maybe you need to set a breakpoint and see.
