What is the command to save as a JSON file?

You can get it by running eval.py with the addition of "--coco_out_dir" and "--coco_out_name":

python -m yolox.tools.eval -n  yolox-s -c yolox_s.pth -b 64 -d 8 --conf 0.001 [--fp16] [--fuse] --coco_out_dir "Output folder for MSCOCO prediction json." --coco_out_name "File name for MSCOCO prediction json."
