Install
pip install npmap -i https://pypi.org/simple
Usage
from npmap import ConfusionMatrix
matrix = ConfusionMatrix(num_classes=80) # coco 80 classes
# cleanup first
matrix.clean()
for (pred, gt) in zip(preds, gts): # for loop for every images
# pred format x0, y0, x1, y1, scores, labels
# gt format x0, y0, x1, y1, labels
# if there is no gt or pred, please set pred=None or gt=None
matrix.add(pred, gt)
# calculate map, map50, etc.
res = matrix.calculate()
# print map
print(res['map'])
# print map50
print(res['map50'])
# print mar
print(res['mean_recall'])
# print mp
print(res['mean_precision'])
# print per class results
print(res['detail'])
... # so on
