This repository just copy and paste PythonAPI from the
official cocoapi, merge the C++ implementation
of COCOeval
in detectron2
into FastCOCOeval. Simplify all unnecessary requirements
and make it easy to install.

gt_json = 'instance_val2017.json'
pd_json = 'predictions.json'
anno = COCO(gt_json)
pred = anno.loadRes(pd_json)
coco_eval = FastCOCOeval(anno, pred, 'bbox')
coco_eval.evaluate()
coco_eval.accumulate()
coco_eval.summarize()The C++ implementation reduces 75% total time compares to the python one.
