AttributeError: 'DetectFeatLmdb' object has no attribute 'env'

[FightingFighting]

when I run python train_re.py --config config/train-refcoco-base-1gpu.json --output_dir $RE_EXP

I just get this result.

I also meet this issue, do you solve this problem?

I am getting the same error.
Were you able to solve this?

@shivangibithel I changed to follow Oscar and VINVL model for vision-language pretraining.

@shivangibithel this problem is because the failure to read the lmdb file, you can try to read lmdb file at first.

note that "lmdb.Error: /img_db/re_coco_gt/feat_numbb100: No such file or directory" in your error message. You are supposed to change your directory in /config/train-refcoco-base-1gpu.json if your command parament is that config file
