Multi vehicle simulation - Queries

Hello !
I followed the instructions mentioned in the dev guide. However I am unable to get the output. This is what I get when I do,
roslaunch px4 multi_uav_mavros_sitl.launch

I needed some help.
Thank you for your time !

There are some problems with multi vehicles simulations,

I have more or less the same issue, I think it is a python problem (migration from 2.7 to 3.7)

I will give an answer once I find a solution

Should I install python 2.7 then ? Thanks much @shrit. Will wait for your reply.

You need to install gazebo_ros package
you are using kinetics, you have already python 2.7 installed on your machine

Apologies ! Yes I have 2.7 python. I will try gazebo_ros and keep you posted.

Hey I installed gazebo_ros. The multi vehicle simulation tutorial works now. Thanks much for your help @shrit !
