Unable to see Carlaviz on the web browser

[MS012086]

Dear Mjxu96,

I am trying to explore the Carla On Linux platform(Ubuntu 18.04). Please find attachment, unable to see the Carla Visualizer in the web browser. I followed your steps, for your reference see below the website

Reference website: https://github.com/wx9698/carlaviz#carlaviz- https://github.com/wx9698/carlaviz/tree/master/examples https://carla.readthedocs.io/en/latest/plugins_carlaviz/#carlaviz

I don't know what I have missed, I am not able to see the carlaviz on the web.

Can you please advise me, what to do next step?

Test Platform: Carla Version: 0.9.9 Linux-Ubuntu: 18.04 Python 3.7

Steps followed:

1. ./CarlaUE4.sh
2. Pull and launch docker image status: docker pull mjxu96/carlaviz:0.9.9 0.9.9: Pulling from mjxu96/carlaviz Digest: sha256:d3e64f97afe0bf158f4897c262e1a271b8737ee8521fb2ae554243ada7afe5bd Status: Image is up to date for mjxu96/carlaviz:0.9.9
3. docker on Linux and Carla server is running on localhost:2000 docker run -it --network="host" -e CARLAVIZ_HOST_IP=localhost -e CARLA_SERVER_IP=localhost -e CARLA_SERVER_PORT=2000 mjxu96/carlaviz:0.9.9
4. Open the localhost: http://127.0.0.1:8080/
5. python3 spawn_npc.py -n 10 -w 5 ERROR: Spawn failed because of collision at spawn position ERROR: Spawn failed because of collision at spawn position spawned 10 vehicles and 3 walkers, press Ctrl+C to exit.
6. python3 manual_control.py

Finally, Unable to see Carlaviz on the web browser.

Thanks & Regards, Saravanan

Hi, when you ran only spawn_npc.py, did you see any visualization in the browser? Could you paste the backend output if you did not see it when only running spawn_npc.py?

[MS012086]

Hi,

Qns: when you ran only spawn_npc.py, did you see any visualization in the browser?

Ans: NO

When i run "python3 spawn_npc.py -n 10 -w 5" following error message is received.

Saravanan@D-12680:~/Documents/Carla-Setup/CARLA_0.9.9.4/PythonAPI/examples$ python3 spawn_npc.py -n 10 -w 5 ERROR: Spawn failed because of collision at spawn position ERROR: Spawn failed because of collision at spawn position spawned 10 vehicles and 3 walkers, press Ctrl+C to exit. ^C
destroying 10 vehicles

destroying 3 walkers

done.

After that, I reduced the number vehicles and walkers."python3 spawn_npc.py -n 2 -w 1" Saravanan@D-12680:~/Documents/Carla-Setup/CARLA_0.9.9.4/PythonAPI/examples$ python3 spawn_npc.py -n 2 -w 1 spawned 2 vehicles and 1 walkers, press Ctrl+C to exit.

After that I am able to see the two vehicles and walkers in Carla Server.

And then I try to run, "python3 manual_control.py" --> pygame window is open but I am not able to see web browser any information, it is blank.

Qns:Could you paste the backend output if you did not see it when only running spawn_npc.py? Ans: Can you please advise me, where the backend output data log is storing, to share it to you.

I just tried to run in carlaviz-master-->examples, following messages are received.

Sorry for the late reply. It seems that one of the port are being occupied in your local machine. Could you check for it?

By the way, could you have a try with Chrome instead of other browsers?
