valid have no results

[beizhengren]

Hi @AlexeyAB , when I validate with my test set,

./darknet detector valid cfg/my-voc.data cfg/my-yolov4.cfg my-yolov4.weights

after run above, I got some text file in results folder, but without contents in them. And, I have not got the json file, as

Rename the file /results/coco_results.json to detections_test-dev2017_yolov4_results.json and compress it to detections_test-dev2017_yolov4_results.zip with the same procedure， I make a validation with yolov3 sucessfully. Thanks!

File /results/coco_results.json will be created for MS COCO dataset only. not for Pascal VOC cfg/my-voc.data and not for your custom dataset.

Use all default files without your changes and strictly follow this manual https://github.com/AlexeyAB/darknet/wiki#training-and-evaluation-of-speed-and-accuracy-on-ms-coco

Did you download http://images.cocodataset.org/zips/val2017.zip ?

I know what is the problem. in val2014, image's name is COCO_val2014_XXX.jpg, but name of val2017 is XXX.jpg
