When I want to run this command:
python ./bellydynamic-adv/SchemaGraph.py

I got this kind of error:
Traceback (most recent call last):
File "./bellydynamic-adv/SchemaGraph.py", line 8, in
import MultiGraph as MG
ImportError: No module named MultiGraph

When i run main.py i got this
Traceback (most recent call last):
File "main.py", line 2, in
context = snap.TTableContext()
NameError: name 'snap' is not defined
