train_val does not work

[FrancescoSaverioZuppichini]

Hello,

when I run

python3 train_val.py

I get the following error:

Traceback (most recent call last):
  File "train_val.py", line 17, in <module>
    from yolo.yolo_v2 import yolo_v2
  File "/Users/vaevictis/Desktop/yolo-docker/YOLO_v2/yolo/yolo_v2.py", line 141
