Hi ken,
Well I think you're correct. If I just do a print vel, it says subscriber object at 'address'...Basically what I'm doing is getting the cmd_vel published from navigation stack.
On this note, is it possible to find out the correct way to get the linear and angular velocities from cmd_vel ?

Hi hitesh,

It would help if you cut and paste the exact error message and include a sample program. I suspect that the program is using the subscriber object instead of the message object, but this is hard to tell without more information.
