carlaviz's Issues

Carla 0.9.13 in remote Docker: "Launch the backend and refresh"

Hi,
just like #6, I have the issue of my browser window staying empty exept for the message "CarlaViz Launch the backend and refresh". I have tried the fixes proposed in the two other issues, but they do not seem to work for me.
I am running both Carla and CarlaViz in a remote docker container and accessing the browser page through a VPN into their network.
My terminal output is:

Make sure you have launched the Carla server.

I am especially curious about the line cat: output.txt: No such file or directory right after the Backend tries to start. After this nginx seems to restart - I am not sure if this is the desired chain of events. Is the backend maybe crashing while it starts?

Thanks

Connection to Carla Server is failed - Carla 0.9.12

Hello,

Anyone know what happened above? The status are below:

• Build & Run Carla from source (latest) on Windows
• Build & Run Carlaviz from docker as instructed on this page https://carla.readthedocs.io/en/latest/plugins_carlaviz/
• Carla Simulator is already running and tested with the scripts from PythonAPI/examples
• But there it is when start running carlaviz from docker with command as instructed on this page https://carla.readthedocs.io/en/latest/plugins_carlaviz/

Thank You

Newest CarlaViz Version with old Carla Version

Hey,

many thanks for creating this tool. I struggled by setting up your latest version of carlaviz with the carla version 0.9.13. You're using a conan repository for the carla dependency, may you can add carla 0.9.13 ? Or explain in a little readme how your new build system works? Or does carlaviz not working when the carla version downgrades? I would like to create a DockerFile to integrate this project into another project which we made from university.

Kind Regards

Apply static data to Carlaviz

HI,
I am trying to proceed with the project of sending carlaviz to actual cars in real time.
I have a 'rosbag' file with vehicle sensor values, but I would like to know how to use it.
This 'rosbag' file contains data for lidar.
I wanted to create an object in 'carlaproxy.cpp', but I'm having trouble connecting it with a pointer.
When I try to apply such static data to carlaviz, I wonder which "cpp" file I have to touch. And could you tell me about the process?

add different port option

Can you please add an option that the api can run on another port.

i would like to run carlaviz behind a reverse proxy and https without having to release port 8080.

small bug in parameters setting

Hi,
thanks for your great work! I tried and success! but I found a small bug, when change the connector_port, it seems that only change the backend service ip, while the frontend still use the default 8081 to connect a websocket. I think they should change simultaneously.

The WebSocket handshake Connection field is missing the upgrade token

I did everything and everything went right just like the instructions and in the video on youtube, but when I open http://localhost:8089/ in the browser I get this error message both in the browser and in the terminal saying : The WebSocket handshake Connection field is missing the upgrade token.
And I have no clue what's wrong !!
Help por favor if you know what may be wrong !!

failed with source build

hello，

I try to use carlaviz with source build and follow the source build instruction, but fail with below error:

RECAST_COMMIT=cdce4e1a270fdf1f3942d4485954cc5e136df1df could not be retrieved, seems no these branch in github. and I change to the master version(RECAST_COMMIT=c5cbd53024c8a9d8d097a4371215e3342d2fdc87)and build again. another error occurred.

error: ‘struct dtCrowdAgentParams’ has no member named ‘obb’
     params.obb[0]  = box_corner1.x;

is this issue really related to RECAST version? if it is, can you share the expect version to me?

Can't display carla information just frontend, using Carla 0.9.9.2

Similar to issue 5 at #5, except we are using Carla 0.9.9.2. Just like in Issue 5, we navigate to localhost:8083 but still have the "Launch the backend and refresh" issue.

Output is below, noting that we don't have the same error that closes the backend:

I can confirm the version using apt-cache, as follows:

$ apt-cache policy carla-simulator
carla-simulator:
  Installed: 0.9.9.2-1
  Candidate: 0.9.9.2-1
  Version table:
 *** 0.9.9.2-1 500
        500 http://dist.carla.org/carla-0.9.9 all/main amd64 Packages
        100 /var/lib/dpkg/status

Is it possible that this 0.9.9.2-1 is somehow different than 0.9.9.2? Has anyone else had this issue and found a way to fix it? I should also note that the simulator version is listed as 4dc4cb81, which I found strange. If anyone else is having this issue, we may be able to find a solution together here

carlaViz with carla 0.9.14

I am trying to use CarlaViz with Carla 0.9.14.

Nothing gets displayed in the browser.
When i try to run the example.py of the latest carlaviz release, I get the following error and cant figure out what the issue might be.

Do you have any idea? Does it have to do with the newer Carla version?

Best regards,
Martin

Carlaviz is not working in 0.9.10.1 version

Hey,

I've just updated Carla simulator and Carlaviz version 0.9.9 to 0.9.10.1.
Since I upgraded, Carlaviz is not working.

I guess it is due to the version mismatch problem, simulator api version is 784d9b9f, not 0.9.10.1.
It is right that version mismatch cause this problem?
Anyone can run Carlaviz on 0.9.10.1?
(I ran Carla simulator before Carlaviz)

Can I run separately, the server runs the carla server notebook runs the docker carlaviz

Today my server runs the carla server notebook runs the docker carlaviz, but has been saying that the server is not open, I ran the carla's own manual.control.py can run, but carlaviz can not run .help sincerely

my order:
docker run -it --network="host" -e CARLAVIZ_HOST_IP="192.168.31.208" -e CARLA_SERVER_IP="192.168.31.249" -e CARLA_SERVER_PORT=2000 mjxu96/carlaviz:0.9.13

support for Carla version 0.9.14

will you release carlaviz for Carla version 0.9.14?

Draw polygons with carla painter

I haven't worked a lot with carlaviz and was wondering about the capabilities of adding my own graphic elements to the visualization. I found that the carla painter supports drawing polylines, points and text, but no polygons. The backend uses xviz for the drawing, which does support polygons, circles, images and whatnot. Is there a reason for this limitation that I should know of or could I simply extend the functionality? Or is this even already planned/implemented?

How to remove the graphics of these buildings

carla: 0.9.14
carlaviz: 0.9.14
These buildings block the perspective of the car, how should we remove them？
I am a beginner who has just used Carlar. If you can answer, thank you very much。

Will you release a new docker which fix for carla version 0.9.12?

Buildings too high

I'm not really sure why this is. But i have updated my carla version to 0.9.14, then I updated the carlaviz version to match. Now when a map is loaded, the buildings seem very high.

lmk if i can be of any further assist.

Have a lovely day!

Missing image tag for version 0.9.13

Currently, the pull command docker pull mjxu96/carlaviz:0.9.13 fails since the tag 0.9.13 is missing.

bug in readme.

The readme says that the environment IP variable for connecting is CARLA_SERVER_IP but it'
s in fact CARLA_SERVER_HOST.

CARLA 0.9.11 running remotely on ubuntu 20.04 with docker on port 2000 using below command:

All traffic lights in carlaviz turn green

I'm trying to run Carla with Sumo and Carlaviz. I've managed to synchronize Carla (client) and Sumo (server), so the vehicles move in Carla based on the routes from Sumo. However, all the traffic lights in Carlaviz are green instead of following the traffic light logic from Sumo. When I run the run_synchronization.py the traffic light manager is Sumo. Shouldn't those changes be depicted on Carlaviz too? I'm using Carla 0.9.11 and Sumo 1.7.0.

Launch backend and refresh

Carla: 0.9.10-1
Carlaviz: 0.9.10

I am getting a Launch backend and refresh issue. I am attempting to run Carla and Carlaviz on an Azure Linux vm and use Carlaviz to stream the sessions to a website connected to the virtual machine. I have both Carla and Carlaviz running and can see Carlaviz in the browser at localhost:8080 working correctly.

When I connect to the website though and direct it to the Carlaviz portion all I can see is the Carlaviz message that says launch backend and refresh. Even though Carlaviz is running correctly when I view it directly on the vm.

Any help would be appreciated. Even if the response is that Carlaviz will not function correctly in the environment I am trying to use it in.
Thank you

How can I customize my lader, lidar, camera data?

Helo!
Thanks to your repo. I can visualize example data(example.py) in web application.
ubuntu : 18.04
carla-simualtor : 0.9.9
installation : using docker image

So, I want to customize my lader, lidar, camera data.
But, I installed carlaviz using docker image, where can I find backend folder & sensor-related-folder?

Thanks.

Low frame rate of the video

Hi Mjxu96,
Thank you for the contribution. I noticed the frontend receives only 2 or 3 frame per second. I want to know how to improve the frame rate of the camera video.

does the "y" position misstakely flipped?

use the latest version (0.9.13), and the test code is as follow:

import time

from carla_painter import CarlaPainter


client = carla.Client('localhost', 2000)
client.set_timeout(2.0)
painter = CarlaPainter('localhost', 8089)


painter.draw_texts("hihi",[7.0, 8.0, 9.0])

broken when changing map

Running from official dockers

Is switching maps supposed to work?

sending vehicle control input to server

Is carlaviz only for visualization ? Is there anyway to control the vehicles by sending control input to the server to steer/accelerate it? I couldn't find any related document to it. Please provide example or documentation if available.

Frontend does not connect to backend when Carla is running on another machine

Hello,

my setup is the following: I have 2 computers, one running Windows and a CARLA build from source. The other one is running Ubuntu 16.04, where I built carlaviz v0.9.9 from source. I am trying to run backend and frontend of carlaviz v0.9.9 on the Ubuntu 16.04 machine. Therefore I start the backend on the Linux machine using

/path/to/carlaviz/backend/bin/backend WINDOWS-HOSTNAME 2000

and the backend successfully connects to CARLA running on Windows. On the Windows machine, I can start the frontend using the mjxu96/carlaviz:0.9.9 docker image with CARLAVIZ_HOST_IP=LINUX-HOSTNAME and it works perfectly.
However, when I want to start the frontend on the Linux machine using

cd /path/to/carlaviz/frontend/ && yarn start 

the frontend cannot connect to the backend and the output is the same as in #5.

Am I missing something?

Websocket connection to 127.0.0.1:8081 failed

Hi, I'm using Carla Simulator built from source.
When I run Carla Simulator (make launch then hit play), then I run docker image with docker run -it --network="host" -e CARLAVIZ_HOST_IP=localhost -e CARLA_SERVER_IP=localhost -e CARLA_SERVER_PORT=2000 mjxu96/carlaviz:latest
I got this error in the browser

This is output from sudo netstat -nlp

This is output from netstat -int

No visualization from CARLA

Hey. I have the same issues as Issue:5 but I have the correct versions.

New Vehicle

Can I change the vehicle model in Carlaviz??

I executed the manual_control.py and Carlaviz, then I changed my vehicle model pushing the backspace button.
However, the vehicle model didn't change in the carlaviz.(localhost:8080)

I need this information because I want to add a new vehicle and run it.
Please help me

carlaviz stops/crashes when multiple frontend react server request for connection

we built our own docker image having only carlaviz in it and running the react client seperately and providing the serverURL accordingly. We found that this architecture works perfectly as well but the issue is when we have the carla and carlaviz running in remote server and provide the public serverURL to the two react server in the 2 different local system ,the carlaviz crashes i,e. there is no handshake taking place with the new request and old connection also breaks. does carlaviz is built to handle single connection or it can handle multiple request??. If it handles single connection how can we achieve to make it accept multiple connection.

License

Thank you for your great work on carlaviz!
Could you please add the licensing info to the repo?

Version mismatch issue

Hi,
Im trying to run this with my compiled carla. But I cant get your backend to work, this is the following error I get while running:

WARNING: Version mismatch detected: You are trying to connect to a simulator that might be incompatible with this API WARNING: Client API version = 0.9.9 WARNING: Simulator API version = 0.9.9-12-gb67ba6c3-dirty terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc ./run.sh: line 16: 6 Aborted (core dumped) ./carlaviz/backend/bin/backend ${CARLA_SERVER_IP} ${CARLA_SERVER_PORT}

As you can see the version is right, my compiled one just has extra things on it (Not sure why) But im sure its 0.9.9

Port mapping for Carlaviz

Hello @mjxu96 ,

thanks for providing this amazing tool.

I am running the carlaviz docker (0.9.12) on a Ubuntu server and want to remap port 8081 to something else (e.g. 8082, since 8081 is busy on my windows host machine). It seems with "docker run --net=host" the port mapping will be ignored (according to https://docs.docker.com/network/host/).

Do you have any suggestions to how to map the port? Thx in advance!

P.S.: I thought port-forwarding on my host Windows machine with
"start /b ssh -L 8080:[server_ip]:8080 -L 8082:[server_ip]:8081 -L 8089:[server_ip]:8089 -f -N [user]@[server_ip]" could help . However, I can only see empty carlaviz in my browser. Is it mandatory to connect local 8081 to [server_ip]:8081?

Best regards,

Yue

Changing port

Hi, wx9698,

thank you for your work with Carlaviz.

I noticed that the default port is 8080 as in:
"3. Open the localhost Open your web browser and go to http://127.0.0.1:8080/. carlaviz runs by default in port 8080. The output should be similar to the following."

Are there any ways to change this port to a different one directly from the Run command? (I wanted to change into 8003 as requested)

Thank you.
