Unable to run deepdrive simulation with custom deepdrive-sim environment (2.0)

[micmarty]

Description

My goal was to build my own, customized deepdrive-sim project in UE 4 and use it with python via deepdrive wrapper (this repo)

My specs

Ubuntu 16.04
Unreal Engine 4.14
deepdrive: DeepDrive 2.0, branch `master`
deepdrive-sim: DeepDrive 2.0  branch `master`

Steps to reproduce

1. Run DeepDrive.uproject in Unreal Editor
2. Modify anything, e.g. reshape SplineTrajectory
3. Build shipping package for Linux (default in: .../deepdrie-sim/Saved/StagedBuilds/LinuxNoEditor)

---

4. Prepare and activate clean conda environment with python 3.6
5. Clone deepdrive repo
6. Run python install.py and wait until downloading is finished (default: ~/Deepdrive)
7. DeepDrive starts automatically and works totally fine
8. Replace everything inside ~/Deepdrive/sim/LinuxNoEditor with the aforementioned custom environment (.../deepdrive-sim/Saved/StagedBuilds/LinuxNoEditor)
   (copied content from right window to left)
   
9. Run python main.py --path-follower or whatever

Crash log

Important lines

Wrong path, hard-coded?

API not working

Couldn't connect

Summary

Did I miss something obvious? What steps are necessary to solve my problem?
I think that this use case (using custom environment) is crucial for new users (ofc in the future, not now probably)

Thanks in advance!

Hi @micmarty - are you able to run the sim directly via the executable? This looks like the sim is not starting. Also, in the sim folder, there should be log files in LinuxNoEditor/DeepDrive/Saved/Logs which may give more of a clue as to why the sim is segfaulting.
