No evaluation speed and inference results on IDOL with OVIS

[Shuaicong97]

Hi, I aim to get the Bounding box info of the OVIS valid set during the inference phase.
I used this command for inference and evaluation as in README:
python3 projects/IDOL/train_net.py --config-file projects/IDOL/configs/ovis_r50.yaml --num-gpus 8 --eval-only MODEL.WEIGHTS VNext/weights/cocopretrain_R50.pth OUTPUT_DIR VNext/outputs/IDOL_OVIS_r50_eval_no_resume

But the log info shows like this:

As you can see, the Eval: 0.0001 s/iter. And WARNING: [COCOEvaluator] Did not receive valid predictions.
Does anyone know how to solve it?

Another question is when to use --resume and add the checkpoint in the output folder.
