请问您是通过什么方式在coco2017test-dev数据集上得到的测试结果？为什么我在coco2017testdev上eval生成的json文件特别大，并且上传coco官网评估会出错？

你好，这是一项非常棒的工作！
我正在复现你们的论文成果，但是
python train_net.py --eval-only --num-gpus 2 --config-file configs/coco/instance-segmentation/fastinst_R50_ppm-fpn_x1_576.yaml MODEL.WEIGHTS /path/to/checkpoint_file
我运行了上面的代码，权重文件是在这里下载的，测试数据集改成了coco2017test-dev，并下载了相应的标注json文件，评估结束之后在output路径下生成了对应的json文件，但是这个json文件特别大，1.1G左右，如果不使用test-dev而是test的话则有2.6G。然后我按coco官网评估要求修改了文件名称，上传json文件到服务器，都没有成功

还请指教，谢谢！
