Connection to Carla Server is failed - Carla 0.9.12 about carlaviz HOT 23 CLOSED

Hi we don't have CarlaViz for Carla 0.9.12.

from carlaviz.

Hi CarlaViz 0.9.12 has been released. Could you have a try and see if it works?

from carlaviz.

Hi Thanks for notifying me.

I just tried it and it works!!!
Thanks for working on this version. If I may know, I would like to know how carlaviz works (backend).
Let me know if u have any references or documentation of carlaviz. I might want to contribute for carlaviz

Thanks again mjxu96 and team!

from carlaviz.

Not sure if you are still interested, but yeah I am looking for contributors to help maintain and develop CarlaViz. Please leave comments here or contact me via email if you are still interested in the project.

Would appreciate any help!

from carlaviz.

same issue here, did you solve it?

from carlaviz.

hi @PierceG6 @RiaMatapurkar what is your docker run command and is your Carla simulator on the same host of CarlaViz container?

from carlaviz.

thanks for the reply, @mjxu96
I tried to use >docker pull mjxu96/carlaviz:latest , it succeed. but when i tried >docker run -it -e CARLAVIZ_HOST_IP=59.10.147.138 -e CARLA_SERVER_IP=host.docker.internal -e CARLA_SERVER_PORT=2000 -p 8080-8081:8080-8081 -p 8089:8089 mjxu96/carlaviz:latest. this is what came out:

THEN, i tried the 0.9.10 version. I succeed, but when I open http://127.0.0.1:8080/ , it shows launch the backend and refresh, but the commandline states this:
Launching backend.
2024-04-01 16:08:00 [INFO] Connecting to Carla Server on host.docker.internal:2000...

I am so confused, i will be grateful for your help

hi the docker run command has been changed after CarlaViz 0.9.14. Could you check the latest document?

And please use the same version of CarlaViz as Carla, e.g. use CarlaViz 0.9.15 for Carla 0.9.15.

from carlaviz.

by the way, your IP in your reply looks like a public IP. You might want to hide it for safety.

from carlaviz.

@mjxu96 Yes both are on the same host

from carlaviz.

command-->docker pull mjxu96/carlaviz:0.9.14
error --> during connect: this error may indicate that the docker daemon is not running: Post "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/images/create?fromImage=mjxu96%2Fcarlaviz&tag=0.9.14": open //./pipe/docker_engine: The system cannot find the file specified.

This is what I see now.

from carlaviz.

during connect: this error may indicate that the docker daemon is not running: Post

Could you try 0.9.14.1 or 0.9.15? And could you check if you can pull other non-carlaviz images?

from carlaviz.

@mjxu96 Thanks for the reply.
I tried the latest docker run command, the pulling was successful, but it shows error that not able to connect to the simulator. Could you please inform my next step, Thanks!

from carlaviz.

looks like it is almost there. Could you try to put the command into one line and discard the \ in the command?

from carlaviz.

@mjxu96 Thanks for all your suggestions I will try with 9.15 but my carla version is 9.14 source build, would that not be a problem?

from carlaviz.

Could you try CarlaViz 0.9.14.1? It can work with Carla 0.9.14

from carlaviz.

@mjxu96 Unfortunatly I get the same error as before:

error during connect: this error may indicate that the docker daemon is not running: Post "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/images/create?fromImage=mjxu96%2Fcarlaviz&tag=0.9.14.1": open //./pipe/docker_engine: The system cannot find the file specified.

from carlaviz.

@RiaMatapurkar could you check if you can pull other images from dockerhub? This error seems like your local docker daemon problem.

FYI the carlaviz images are hosted at https://hub.docker.com/r/mjxu96/carlaviz/tags

from carlaviz.

@mjxu96 I was able to but I will just check again to see if there is a problem on my end! Thanks for all your help, I will write you an update on Monday

from carlaviz.

@mjxu96 Thank you for your help!! now I can run the carlaviz.
