What am i doing wrong?

[Wearwolfy]

I am trying to run the lane detection conde simulation but I can't get it to work? Do you know what I am doing wrong? I am running it on Ros melodic and Ubuntu 18.04 on a vm.

I am trying to clone this package https://github.com/wilselby/diy_driverless_car_ROS.git and build the package but I am unable to do so which says unable to find two different packages named yocs_cmd_vel_mux and ecl_exceptions. . Please help me the best way to clone this package with all the required dependencies.

[wilselby]

Clone these if they aren't in the apt-repo
https://github.com/yujinrobot/yujin_ocs/tree/devel/yocs_cmd_vel_mux
https://github.com/stonier/ecl_core/tree/devel/ecl_exceptions

[saitejaallam]

I have cloned these two packages as well but after cloning these packages I am unable to build the packages. It shows an error "Packages with unknown build type exists. Can not build workspace with packages of unknown build_type" .Please help me if I am missing something while cloning all these packages.

running this code $ python rosbag_to_csv.py -o output/walker/ -i data/walker/ is giving me ERROR: ['/racecar/ackermann_cmd_mux/output', '/img_node/intensity_image']
Can you tell me where am I going wrong?

While running drive_model.py node on python 2.7 it throws an error of " Require Tensorflow 2.2 or greater". For Tensorflow 2.2 it requires python 3 but python 3 does not support ROS.
What can be done in this case?

Any solution for this? I am getting the same error.

Does the ROS .bag file have those topics in it?

[Praj390]

When I use rosbag info, i get this info

It looks like there is no topic '/img_node/intensity_image'. Also, when I see the rostopic list, there is no such topic there.
Should I change the topic to ' /openmv_cam/image/raw ' in bagutils.py file? or is there any other way?

[wilselby]

Can you post the output when you change the camera topic to the ' /openmv_cam/image/raw ' topic? It's also odd it complained about the '/racecar/ackermann_cmd_mux/output' topic since that looks like it's in your bag. Is the bag file in the right directory of the command line argument?

[Praj390]

The problem is solved. The solution is to change the topics in bagutils.py files and the path is given. I changed that path to an absolute path and it worked. I don't know but the relative path was not working.
