I am attempting to use Google Colab to run https://github.com/ARiSE-Lab/deepTest deep neural network software developed on Ubuntu. I was able to run the install.sh with small modifications. I was successful, after adding "!", in loading:

! sudo apt-get install python-rosbag 
! sudo apt-get install python-genmsg 
! sudo apt-get install python-genpy 
! sudo apt-get install python-rosgraph-msgs1re

This installed many files including:

Setting up python-rosbag (1.13.5+ds1-3) ...

However, when I ran the program generate_hmb3.py whose 2nd line is:

import rosbag

I got an invalid syntax error message. When I changed the line to read:

import python-rosbag

I got the message:

File "<ipython-input-12-37a7e266f3af>", line 7
import python-rosbag
SyntaxError: invalid syntax

Any solutions to this problem?
