Where is SeqTR/refcoco-unc/instances_cocofied_train.json?

[PhoenixZ810]

When I try to evaluate on ref coco, there is an error:
FileNotFoundError: [Errno 2] No such file or directory: 'datasets/SeqTR/refcoco-unc/instances_cocofied_val.json'
Where can I find SeqTR/refcoco-unc/instances_cocofied_train.json? This file is not in the preprocessed directory refcoco_unc.

I have updated the README for dataset preparation and the corresponding tools.
Please refer here to generate datasets/SeqTR/refcoco-unc/instances_cocofied_val.json and some others.

I find refcoco-unc in tools/seqtr2coco/convert_mix_ref.py :

but it's not in refcoco data structure:

[shenyunhang]

You are right. I have updated the data structure. refcoco-unc is needed and downloaded from SeqTR.

category_id < num_classes, how to fix this?

The class IDs are filled during the inference process at here and here.
It should make sure that one of the above codes is used when inferring a registered dataset.
