render.py - delete some object,error occurs in parse_edit_config_and_text_encoding

[fisheatmice]

when I use config.yaml

edit:
  objects: ["lawn", "tree", "bicycle", "building", "road"]
  operations: "deletion"
  targets: "bicycle" # the target object should be chosen from the object list
  threshold: 0.198 # leave it empty if using argmax

Traceback (most recent call last):

    return edit_dict, text_feature, targets[idx]
IndexError: list index out of range

It seems parse_edit_config_and_text_encoding's return
should be
return edit_dict,text_feature,objects[idx]
