When I perform self-training I get an error file

When I perform self-training I get an "./CutLER/cutler/output/inference/instances_predictions.pth"
`python train_net.py --num-gpus 8 \
--config-file model_zoo/configs/CutLER-ImageNet/cascade_mask_rcnn_R_50_FPN.yaml \
--test-dataset imagenet_train \
--eval-only TEST.DETECTIONS_PER_IMAGE 30 \
MODEL.WEIGHTS output/model_final.pth \ # load previous stage/round checkpoints
OUTPUT_DIR output/ # path to save model predictions`

So i can not do next step.

Start with tools/get_self_training_ann.py at line 111 and the preceding self-training command using train_net.py. Check why output/inference/coco_instances_results.json is not present when the script runs; done means the next self-training step can open the expected prediction file without FileNotFoundError.
