Problems with the latest release (v1.4.0) Linux assets

[rajat2004]

Bug report

• AirSim Version/#commit: Release v1.4.0
• UE/Unity version: NA
• autopilot version: NA
• OS Version: Ubuntu 18.04

What's the issue you encountered?

I was trying out the latest release and had various problems, so this issue in order to know if these are isolated errors or others are also having these. Will keep updating the issue as I test more.

There seems to be some common errors from missing assets -

• Blocks - Blocks.sh to run the binary is missing, also the packaged Blocks env seems to be not present, only the Editor stuff is present.

• AbandonedPark - Car or Multirotor vehicle gets created, however the Car doesn't seem to move at all when trying using the arrow keys. Subwindows are empty except for Scene, and the car disappears when running hello_car.py script and later crashes with a seg fault. Stacktrace -

Stack trace similar to MSBuild therefore omitted

LandscapeMountains seems to working, but haven't tested thoroughly.
Also haven't yet used on Windows

Settings

Default settings, sometimes only to change SimMode

How can the issue be reproduced?

1. Download the specific release asset from here
2. Unzip and run

Include full error message in text form

Hi @rajat2004 and @rambodrahmani, I have uploaded new binaries for both windows and linux that should address most of the issues you've been experiencing:

• Errors related to missing assets should all be fixed now. This was happening because the Unreal Build Tool was skipping assets that weren't explicitly referenced. A level referencing all vehicle pawns was included in the build to fix this.
• Blocks: I am not able to repro this issue personally. I tried unzipping the binary with 7zip, Thunar's archive manager, and Windows Explorer's extract options; with each extraction I saw both the Blocks.sh script and the binary in the archive. I strongly suspect this was happening due to a corrupted download.
• AbandonedPark: this environment was crashing due to a bug in Unreal's landscape rendering. I replaced the offending landscape with a static mesh and the environment is now running for me.
• MSBuild: this environment has been updated with the fix for the missing assets error.
• Africa: I checked an older release of this environment and the prompt was present, so this isn't anything introduced in this release. Because the prompt disappears after pressing the ok button, I don't think this a major issue that blocks any functionality.

The Building_99, TrapCamera, and Zhangjiajie environments were also updated due to related issues that are now fixed. Please test again with the latest version of these binaries and let me know if you see any errors.

@zimmy87 Thanks a lot for looking into this issue and updating the binaries! I haven't tested all the envs, just tried Blocks and few others and they seem to be working correctly.

• Blocks, AbandonedPark, MSBuild, AirSimNH tested to working and not crashing (only Car simmode right now)
• Regarding UE4 skipping assets, I believe it might even fix the problem of Fix Weather API crash #3009, after the game thread fix is applied (currently using the Weather API crashes due to not running in Game thread). Though personally, I believe its best to fix the problem of Weather assets by properly loading them such that they get referenced, that's becoming a much bigger task than thought, this can be good way currently to fix the problem
• About the missing Blocks files, could be a corrupted download, but it unzipped correctly and the size was also correct, so no idea.
• Had a strange behaviour in the MSBuild env, the trees and buildings doesn't seem to have collisions. The depth rendering works on the outside, but the interior is missing. Is this an intended behaviour?
  
  

[zimmy87]

Hi @rajat2004, the Africa and MSBuild2018 environments have been updated with the following changes:

• the default map used in Africa was changed to one that doesn't have the "Select Day:" prompt and there's a wider variety of animals that spawn closer to the player start as well
• the collisions were fixed in MSBuild2018 so that vehicles now collide with buildings and trees

Since these were updates to the environments and not the AirSim code, these binaries have been updated in place and are available at the same location for v1.4.0

[zimmy87]

The issues being reported look have been resolved by the re-uploaded binaries so closing this.
