code originally from https://github.com/fizyr/keras-retinanet
# Arguments
model : The model to evaluate.
generator : The generator that represents the dataset to evaluate.
iou_threshold : The threshold used to consider when a detection is positive or negative.
obj_thresh : The threshold used to distinguish between object and non-object
nms_thresh : The threshold used to determine whether two detections are duplicates
net_h : The height of the input image to the model, higher value results in better accuracy
net_w : The width of the input image to the model
save_path : The path to save images with visualized detections to.
# Returns
A dict mapping class names to mAP scores.
