question about Normalize

[Feynman1999]

in /mmedit/datasets/pipelines/normalization.py, Normalize class , call function, why we need the line 40?

Hi, those lines (L39-L44) are added to support video data format. For example, in video super-resolution data pipeline, results['lq'] is a list of video frames.

yes, I know that, But why need two for loop, L40 and L43

[hejm37]

I see, the outer for loop is not necessary and will be removed. Thanks for your feedback!
