I run the python data/split_coco_dataset_voc_nonvoc.py ，and I get this problem, how can I solve it.

Split 1: 346721 anns; save to ./data/COCO/annotations/split_voc_instances_train2014.json
Split 2: 258186 anns; save to ./data/COCO/annotations/split_nonvoc_instances_train2014.json

You should first download the COCO 2014 dataset here, and place them accordingly under the instructions I provide in the README.md file. This error indicates that you did not correctly set up the dataset.

thanks for your reply, I have downloaded the COCO 2014 dataset

a problem had occured when I run the:
python train.py --save-folder weights/VOC_split1_pretrain -d VOC -p 1 -max 50000 --steps 30000 40000 --checkpoint-period 4000 --warmup-iter 1000 --setting incre --split 1

the code of python train.py --save-folder weights/COCO60_pretrain -d COCO -p 1 had finished

I have no idea what the problem is with the information you provide. By the way, you may try to avoid using Chinese characters in the directory path since it may sometimes cause some weird errors that are hard to be noticed. Hope it helps. Thanks.

Has your problem been solved? I have encountered the same problem as you. Can you tell me how you solved it? Thank you!
