How can I save the inference results into json format?

[didnmj]

from detectron2.evaluation import COCOEvaluator, inference_on_dataset from detectron2.data import build_detection_test_loader evaluator = COCOEvaluator("test", cfg, False, output_dir="./output2/") val_loader = build_detection_test_loader(cfg, "test") inference_on_dataset(trainer.model, val_loader, evaluator)

I think this code is for evaluation. I want to save the inference result for each image as json.

inference_on_dataset will save in your output directory what are you looking for, it should be the "coco_instances_result.json" or something similar.

I want to save the predicted image in the coco format json.

Have you seen that file in your output folder? It has all the result, you can visualize the annotations as the cocoAPI demo
