TypeError: Can't instantiate abstract class Euclidean with abstract methods get_metric, score_pairs

[SWRDFK]

Thanks for your excellent work! I met this problem when I run the file examples/softmax_loss.py.

Traceback (most recent call last):
File "softmax_loss.py", line 217, in
main(parser.parse_args())
File "softmax_loss.py", line 104, in main
metric = DistanceMetric(algorithm=args.dist_metric)
File "/home/open-reid/reid/dist_metric.py", line 13, in init
self.metric = get_metric(algorithm, *args, **kwargs)
File "/home/open-reid/reid/metric_learning/init.py", line 25, in get_metric
return __factory[algorithm](*args, **kwargs)
TypeError: Can't instantiate abstract class Euclidean with abstract methods get_metric, score_pairs
