SImulations fail on the scoring server

[Sushant-Chavan]

Hi,
I am a member of a team participating in the robocup-at-home-2021 challenge.

We are facing an issue when running the simulations on the devrt server. The server seems to build the docker images fine. But after that when it tries to run the simulation, it returns an error.

Upon logging into the devrt website and checking the build status, the following error is displayed:

(HTTP code 500) server error - OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: Running hook #0:: error running hook: exit status 1, stdout: , stderr: nvidia-container-cli: initialization error: nvml error: driver/library version mismatch: unknown

Please let us know what could be done regarding this.

Thanks and regards,
Sushant

We have experienced this problem a few days ago due to the automatic update of the Nvidia driver on the simulation server.

I think the problem is fixed now. But, please let us know if you experience any further problems.

[Sushant-Chavan]

The simulations are working now. Thanks!

@TomohiroOno33 Sorry we have experienced the system outage again (noticed you are suffered from the log).
Should be fixed very soon.

The simulation server is up now. Please let me know if there are any problems.

For the The complete state of the robot is not yet known. warning, it seems all the joints listed here are the fixed or free joint which state is known as obvious or undefined.

Also corresponds to the list of joints defined here:

May be the issue of the timing of the moveit startup and SRDF loading?
SRDF should be loaded before the moveit starts.

@TomohiroOno33
Is this problem happen only in your local simulator environment? or also happen in the build system?

[TomohiroOno33]

This is maybe happening only local.
I have confirmed that this is happening on multiple local computers.

May be the issue of the timing of the moveit startup and SRDF loading?
SRDF should be loaded before the moveit starts.

The problem happens when I run hsrb_robocup_dspl_docker.
Does it mean that I press the simulator start button too early?

[yosuke]

Does it mean that I press the simulator start button too early?

Yes, this is most likely the reason.

[TomohiroOno33]

I understand.
I'll try to wait a bit before starting it.
