how to generate the new json file

[flylili001]

I have got the json file from espnet. But in SemanticMask, we should add the start and end information into the json file. How should I do? Otherwise espnet/utils/io_utils.py can't read the start and end info from "y_feats_dict". Thank you.

hi, you need to modify the script produced json file.
