Open_Loop_Control Fetch not working for warehouse_0000 scene

Closed this issue · 3 comments

What platform am I on? What are my system specifications? Do I meet the minimum specifications for the Unreal Engine?

Ubuntu 20.04

What commit of the spear repository am I on? Am I synced to a specific tag, or am I synced to the head of the main branch?

main branch

What SpearSim executable am I using? Did I build it myself or download it? If I downloaded it, is my code synced to the correct tag?

I'm using the official release for the linux version

What am I attempting to do, what do I expect to happen, and what actually happened?

Attempting run the open_loop_control fetch run.py with warehouse_0000 scene. Although, this works with other scenes apartment_0000 and debug_0000. To add to this, warehouse_0000 scene works fine when I run "python tools/run_executable.py --executable path/to/executable --scene_id warehouse_0000"

Here is the complete console output from when when I created the spear.Env object in my application.

Hi, thanks for the questions. Can you please format your error message and other command-line invocations etc as code blocks so they're easier to read?

Hello @mikeroberts3000. I formatted. Thanks for the prompt reply.

Thanks for updating. In general, we don't necessarily expect our example apps to work on scenes other than the default ones. However, in this specific case, if you're willing to modify the source code and recompile, I think you can simply comment out where nav_mesh_ is initialized on line 204 of SimulationController.cpp, and again where it is cleaned up on line 251.

I understand this is a pretty janky workaround. The good news is that we're working on a new system for spawning agents that will enable mixing-and-matching agents and scenes in a cleaner way, and we'll have a more concrete update in a few weeks. Thanks for bearing with us 😅
