请问par 的evaluation代码对多类适用吗？

[zhangshitoday]

`fast-reid/projects/FastAttr/fastattr/attr_evaluation.py def get_attr_metrics(gt_labels, pred_logits, thres):

    eps = 1e-20

    pred_labels = copy.deepcopy(pred_logits)
    pred_labels[pred_logits < thres] = 0
    pred_labels[pred_logits >= thres] = 1

` 请问这里只考虑2类吗，像age属性有[0,1,2,3] 四类，是适用的吗

应该是不行的，可能需要自己改写一下
