Plan for a new Linux release? / PX4 Master compatibility

[Jaeyoung-Lim]

The latest Airsim release (v1.2.2) is already a year old.

Are there any plans to release a new Airsim release for Linux?

[madratman]

Hey @Jaeyoung-Lim. Yes, we're planning for a new release very soon! We're looking to merge/close most of the open PRs before that. Stay tuned, and thanks for your patience.

[Jaeyoung-Lim]

@madratman Thanks, do you have a ETA on when this will happen?

[madratman]

We're aiming < 1 week.

[Jaeyoung-Lim]

@madratman Awesome! Thanks

[Jaeyoung-Lim]

@Tcloser Please don't hijack the topic of this issue

[madratman]

@Jaeyoung-Lim, we just made https://github.com/microsoft/AirSim/releases/tag/v1.3.0-linux with only Blocks for now. I noticed in your PX4 PR, Blocks would be enough to unblock. We're adding other environment binaries incrementally. Thanks for your patience!

[Jaeyoung-Lim]

@madratman Thanks! However, the Blocks environment crashes when I try to run Blocks.sh Any idea why this is happening with the new release? I can run 1.2 without any issues

The log is as the following:

$ ./Blocks.sh

[rajat2004]

@Jaeyoung-Lim It is working correctly for me on Ubuntu 18.04. There are quite a lot of memory allocation errors in your output, maybe try keeping an eye on nvidia-smi while running the binary? You could also try using the -windowed and -ResX,-ResY options to reduce the rendering and see if it helps Don't think memory should be an issue, especially since there's a line in between which says it's reducing the Texture memory to 1000MB, but doesn't hurt to check

Edit: Missed this line - Out of Device Memory, Requested=15360.00Kb MemTypeIndex=7 Memory is the problem then

[madratman]

@Jaeyoung-Lim does ./Blocks.sh -windowed -opengl4 make any difference?

[Jaeyoung-Lim]

@madratman That actually made a difference. What does the command arguments change?

[madratman]

It changes the rendering API unreal uses from vulkan to opengl. With ue 4.21, unreal switched to vulkan in linux by default for better performance. However, we have seen vulkan use more memory than opengl at times.
unreal is still resolving issues wrt the vulkan transition (which might explain higher mem usage) and we suspect it might be complete happen with ue 4.25. as a fallback, they let you use opengl backend with that command line arg in general, here's a complete list - https://docs.unrealengine.com/en-US/Programming/Basics/CommandLineArguments/index.html

[saihv]

As a side note, the size of the window also determines the resolution UE draws the world at. Smaller the window, lower the memory usage and higher the average FPS. It can either be resized manually or through the flags ResX and ResY: ./Blocks.sh -windowed -ResX *** -ResY ***

[Jaeyoung-Lim]

@madratman Thanks for clarifying, my laptop is also at the edge of running Airsim, so I will also try testing on my desktop.

[Jaeyoung-Lim]

This release currently doesn't work with the PX4 master of today. It fails with the following errors

This seems to be introduced by https://github.com/PX4/sitl_gazebo/pull/411

What would be a good way to keep both is some sort of a CI so that this kind of regression can be detected not only when there are releases?

@madratman @lovettchris FYI

[rajat2004]

What would be a good way to keep both is some sort of a CI so that this kind of regression can be detected not only when there are releases?

Any ideas for a more thorough CI would be great! Currently, Travis CI for AirSim is limited to building the AirLib code and doesn't even involve UE and the engine-related code. Therefore, many times, problems with that get missed. UE is very heavy, just for Linux takes ~1hr to build on my system, and takes up more than 40-50 GB. Building on Travis just won't be feasible, never mind running which will require GPU

I think manual testing from time-to-time and issues from users seems to be the only way to me right now

[Jaeyoung-Lim]

@rajat2004 Would it be possible to run Airlib without UE? that would simplify the CI problem greatly

[rajat2004]

AFAIK don't think that's possible. All the physics, timers, etc are done by UE But @madratman @saihv @sytelus would be much more knowledgeable about this

[madratman]

I think it's possible, as AirLib is a standalone cpp lib. Looking at the code, I think we need a json file for px4 sitl, setup px4 sitl, and make a standalone c++ script which runs the bare minimum for px4 sitl . something on the lines of

# prereq
pip3 install --user empy toml;

# clone PX4
mkdir PX4 && cd $_;
git clone https://github.com/PX4/Firmware.git;
cd Firmware;

[Jaeyoung-Lim]

@madratman In the meantime, would it be possible to do a new release including https://github.com/microsoft/AirSim/pull/2549 ?

[bys1123]

@Jaeyoung-Lim Did you tested it, I‘m trying to test it, but not finished yet.

[madratman]

@Jaeyoung-Lim can you clarify if it's breaking both SITL and HITL? Yes, we can make a new release post merging it

[TSC21]

It should since the pipeline for the sensors is the same.

Why not use a Docker container with UE already in place: https://hub.docker.com/r/connorlanigan/unrealengine-docker/? Or even create a Dockerfile which extends from this one with the required tools and use it in CI?

[madratman]

@TSC21, we have something on that lines here https://microsoft.github.io/AirSim/docker_ubuntu/ and here https://github.com/microsoft/AirSim/tree/master/docker. I believe ue4-docker is more mature than the one you linked. However, the issue is we can't compile UE from source in something like travis as it takes a fairly long time to do so. Instead, what is better is to have a dedicate gpu based vm, and make a installed build of Unreal on that machine, so time isn't wasted to compile UE on each CI build. We'll need to do this via az pipelines.

[madratman]

@Jaeyoung-Lim Did you tested it, I‘m trying to test it, but not finished yet.

It works well for me on linux.

[madratman]

https://github.com/microsoft/AirSim/releases/tag/v1.3.1-linux is here

[bys1123]

[madratman]

I think the doc says to start px4 sitl first. Once you see - waiting for simulator to connect in the terminal, then hit run on unreal engine.

[madratman]

You can pass windowed, resx and resy params as mentioned earlier in the thread for non full screen.

[bys1123]

@madratman Thanks, start Blocks -windowed -ResX=640 -ResY=480 Works, need to use these params together, different with 1.3.0.

[bys1123]

@madratman I tried different timing open px4 sitl and airsim, all get this error on windows.

[Jaeyoung-Lim]

@madratman When running with px4 sitl, airsim crashes on my machine. Were you able to get something like QGroundcontrol to control the vehicle?

@Jaeyoung-Lim Do you have the error information on PX4 side?

[Jaeyoung-Lim]

@bys1123 there is no error on the px4 side

[madratman]

I am seeing both the error logs now. I am not sure how come they didn't show up earlier on my machine. Looking into it.

[Jaeyoung-Lim]

Seems like Airsim process exits before that occurs in my case...

[madratman]

Can you try running PX4 before AirSim. Not directly related: but I am definitely noticing the freeze on exiting unreal issue with PX4 - https://github.com/microsoft/AirSim/issues/2112. Maybe @lovettchris can advice w.r.t. that.

Debugging a bit, I think this is what's happening (cc @Jaeyoung-Lim @TSC21 @lovettchris)

• The first few calls of sendHilSensor do run fine. (It seems to me when I was testing #2549, I exited the process way too quickly before the error messages starting popping up.)

• Now, after the first few successful, calls, the if (!received_actuator_controls_) becomes true (as well, at least, I am not sending any control commands), and the function simply returns on L1319.

• Now, it does that a few times and keeps on returning, without updating the last_hil_sensor_time_ (which you can see is happening in L1326.

• By the time this has happened for >100 milliseconds, we can see why it's failing - the condition on L1311 is - if (last_hil_sensor_time_ + 100000 < now) is now true, aka last timestamp of hil msg is too old, and hence the error log on the terminal.

• Interestingly enough, we actually still return on the function as (at least in my case), !received_actuator_controls_ is still true - and therefore no message is sent.

I am actually surprised how this wasn't failing earlier? Or perhaps people who use PX4 always have received_actuator_controls_ = true?

Edit: I've opened https://github.com/microsoft/AirSim/pull/2556 to fix this.

[Jaeyoung-Lim]

@madratman Awesome, thanks for the investigation.

I have also tried starting px4 before but still results in the same. I believe no one really noticed since most people using Airsim used v1.8.2(Nov 21, 2018) of PX4 as written in the documentation.

I will try on a more powerful desktop to run it with the UE4 editor

[madratman]

Alright, with the PR, I see ~38 messages being sent successfully.

However, post that we start returning from the function when !received_actuator_controls_ condition becomes true. The comment in the code says // drop this one since we are in LOCKSTEP mode and we have not yet received the HilActuatorControlsMessage.. I am assuming this the desired behaviour? So, after the first 40 or so messages, it doesn't send out anything, until a MavLinkHilControls cmd is received.

[madratman]

Added a minimal prototype for the AirLib minus UE + PX4 SITL idea from https://github.com/microsoft/AirSim/issues/2477#issuecomment-611082708 in https://github.com/microsoft/AirSim/pull/2558

[madratman]

terminating with uncaught exception of type std::runtime_error: UdpClientPort socket send failed with error: 9

I haven't been able to fix the throw, but it's happening in sendHeartbeat. I am not sure what error code 9 means? https://community.particle.io/t/udp-error-codes-listed-anywhere/18775/3 says NOTUP -9 // Interface is not currently Up

[Jaeyoung-Lim]

@madratman Could we reopen this issue so that it gets better visibility?

[madratman]

Sure. I've updated the docs to reflect that latest release of airsim binaries works with latest release tag of px4 (1.10.1)

[clintlombard]

The latest PX4 release (v1.11.0) no longer works with AirSim in SITL, although v1.10.1 and v1.10.2 did.

3010 might also be related to this issue in the broader sense of PX4 compatibility.

[Jaeyoung-Lim]

@madratman From a previous discussion, I briefly recall that we were discussing on detecting PX4 related regressions using a CI. Has there been any progress on this front?

[krisklau]

Any updates on px4 v1.11 compatibility?

[Jaeyoung-Lim]

@jonyMarino Are there any activity to resolve this and preventing it from happening again?

[jonyMarino]

Hi @Jaeyoung-Lim! Compatibility with PX4 is a major concern. We are not working on this right now, but I will update if no one from the community submits a pull request.
