Running example error？

I want to know which version of python do you use? This is my problem：
python3 running result:

python3 ../patch.py hello.exe hello.py
Traceback (most recent call last):
File "/home/zhangzheng/pepatch/example/../patch.py", line 7, in
from core.patcher import Patcher
File "/home/zhangzheng/pepatch/core/init.py", line 2, in
from binary import *
ModuleNotFoundError: No module named 'binary'

python2 running result：

python2 ../patch.py hello.exe hello.py
Traceback (most recent call last):
File "../patch.py", line 7, in
from core.patcher import Patcher
