Simulator goes offline after clicking "Run Simulation" #1787

Closed ruoxianglee closed 3 years ago

ruoxianglee commented 3 years ago

Hi, I am using svl simulator 2021.1.1 from a prebuilt binary on Ubuntu 18. I have run the simulator successfully before. But when I want to start the simulator today, it doesn't work.

The simulator can connect to the cloud, and when I trying to Run Simulation in the web user interface, I got the information "Error on latest run: Simulator bd313d60-5c19-4fe6-b097-7ed32a84104c unresponsive during starting."

I have no idea about this error, could someone help me on this issue? Thanks.

@ruoxianglee We are unable to reproduce this issue on our side. Could you please share some more details such as the log file for the error?

Also, if you could try deleting the data folder and linking the simulator again?

Hi I @EricBoiseLGSVL I am experiencing the same issue. I have started from a fresh machine, but any simulator release is connecting to the simulator....it always get disconnected and just says...."disconnecting" or something like that without point errors...

Using the svlsimulator-linux64-2021.1.1 simulator executable downloaded from the website: link and create the cluster create simulation and run

error from the website says Error on latest run: Simulator 9c18ca9e-0230-44f2-a324-a4d0852b4f5b unresponsive during starting

the simulator looks like this. lgsvl_error I tried it on 3 desktops and they have the same problem (They used to work)

What does your config file have in it? image

Mine looks like this: headless: false read_only: false api_hostname: "localhost" api_port: 8181 cloud_url: "https://wise.svlsimulator.com"

EricBoiseLGSVL commented 3 years ago

Please remove headless and read_only and see what happens

bruce-almon commented 3 years ago

Please remove headless and read_only and see what happens

It didn't change the behavior. The same error still exists Thank you

Let's bring @thisisdavidfrank on this to look at the account.

EricBoiseLGSVL commented 3 years ago

@bruce-almon can you remove the quotes on the cloud_url please

alexandrx commented 3 years ago

If it serves as reference to this discussion. I also experienced the same behavior with version 2021.1: it goes to offline mode after clicking on run simulation. I gave up trying on version 2021.1, installed 2021.3 instead, and it is running the simulation without problems. The new version requires one to create a new cluster due to incompatibilities, I just updated the cluster of the simulation and it ran.

I have same problem on version 2021.1 !!! Actually, I have a experiment on San Francisco with 2021.1 and it happens. 2021.2 and 2021.3 can run simulator. However, San Francisco has rotate problem on other version.

marcusvinicius178 commented 3 years ago

Hi the same here....I need to use the 2021.1 because it is the only version that Apollo works well.

The 2021.2 releases localizate the vehicle wrongly And in the 2021.3 release there is a delay in odom/imu messages that avoids the path planner to work.

If someone know how to enable connection again with 2021.1 please let me know what to do... Thanks

@bruce-almon can you remove the quotes on the cloud_url please Hi, thanks for your support,. I removed the quotes on the cloud_url 

api_hostname: "localhost"
api_port: 8181
cloud_url: https://wise.svlsimulator.com

and also tried removing the cloud_url line completely.

api_hostname: "localhost"
api_port: 8181

The same problem persists.

@marcusvinicius178 what do you mean "And in the 2021.3 release there is a delay in odom/imu messages that avoids the path planner to work."? For those that can't use 2021.3 we are looking into the issue. Please check no software is blocking connection to the URL and we may need emails to the accounts to see if there is a database issue. We also need to look at the player logs so please post those. This will might help because we can't reproduce this locally.

Please see the attached player log file I found for Linux binary under ~/.config/unity3d/LGElectronics/SVLSimulator Player.log Please let me know if you need additional info

Thanks for your support~ Bruce

Sorry about that. I had another editor open accidentally Please see the new log file attached. The connection issue https://github.com/lgsvl/simulator/issues/1787#issuecomment-933839448 is still here. Player.log

EricBoiseLGSVL commented 3 years ago

We are still looking into what the cause of this is. Sorry about the wait. I'll post as soon as we find something

eagafonovlge commented 3 years ago

Thank everyone for the report! We have identified the root cause, and the fix should be already available on https://wise.svlsimulator.com

Could you please run a simulation with any type of bridge using the 2021.1 and 2021.1.1 simulator versions?
