When I try to run client.connect() function an error occurr:

Traceback (most recent call last):
File "/home/kamerider/ambf_walker/PendTesting/first_test.py", line 14, in
_client.connect()
File "", line 196, in connect
File "", line 123, in create_objs_from_rostopics
UnboundLocalError: local variable 'base_obj' referenced before assignment

This variable is referenced in line 123, while it is actually first assigned value in line 127. How can we deal with this issue?

This file /home/kamerider/ambf_walker/PendTesting/first_test.py doesn't seem to be part of the AMBF repo. Is this your own code? You can paste it here so I can see what's going on.

I am running the same code and it works on fine on my machine.

#!/usr/bin/env python
import sys
from os import sys, path


from Model import DoublePendulm
import rospy
from ambf_client import Client

_client = Client()
_client.connect() # its failing hereon Simon machine, im not sure why. 
rate = rospy.Rate(1000)
pend = DoublePendulm.DoublePendulum(_client)
while 1:
    pass

Do you have a GitHub link for this code which I can use to reproduce the issue as the information is not sufficient for me to look at anything. Also which AMBF branch in this using?

adnanmunawar commented

Oh I think I got it. See if the latest commit fixes the issue.

So much apologies for my late response! Yeah the actual error line is in ambf/ambf_ros_modules/ambf_comm/scripts/ambf_client.py, sorry for my ambiguous description. Also the new commit has already fixed this issue, thanks a lot for your help!!
