Hello

Make sure you have the data folder in the following location '/home/catkin_ws/src/ros_aiml/data, please check the launch file if you want to change the location of data folder

File "/home/ros/catkin_ws/src/ros_aiml/scripts/aiml_server.py", line 22, in load_aiml os.chdir(data_path) it was a silly mistake i forgot the usr in the path so its /home/ros/catkin_ws/src/ros_aiml/data
