Stuck on ./runYOLO

[BigfanofGreenDay]

I ran it on Raspberry PI 3b. Previous steps are fine, but I stuck on "./runYOLO". I tried "sudo ./runYOLO", but still the same:

{'dataset': '/home/pi/Traffic_sign_detection_YOLO/dataset', 'yoloConfig': {'metaLoad': '/home/pi/Traffic_sign_detection_YOLO/darkflow/built_graph/tiny-yolo-voc27.meta', 'threshold': 0.01, 'pbLoad': '/home/pi/Traffic_sign_detection_YOLO/darkflow/built_graph/tiny-yolo-voc27.pb', 'gpu': 0.0, 'labels': '../labels.txt'}}

Loading from .pb and .meta
Traceback (most recent call last):
File "YOLOtest.py", line 126, in
det = objectDetector(video=False)
File "YOLOtest.py", line 21, in init
self.tfnet = TFNet(self.options)

Please help me, thx

What version of tensorflow are you using?.

import tensorflow as tf
tf.__version__

>>> import tensorflow as tf
>>> tf.__version__
'1.13.1'
>>> 

Also check if your python is pointed to python3 interpreter
