Won't load any Scenario just main menu

[devimauz]

Hey, My problem is it don't want to load any scenario just opens the game and puts me in the main menu. Under Windows it works well but not on Ubuntu 20 Sometimes its give the loading screen, shows like everything loaded but nothing happens. BeamNG.drive is 0.29.1.0.0 (BeamNG.tech)

It's hangs at

>>> beamng.scenario.load(scenario)

Thanks!

Hi, are you using Ubuntu to run BeamNGpy and BeamNG.tech, or just BeamNGpy and the simulator is running on Windows?

[devimauz]

I'm using BeamNGpy and BeamNG.tech on Ubuntu.

[aivora-beamng]

What is the version of BeamNGpy you are running on the Ubuntu host? There may be a mismatch, you should be running version 1.26.1 of the library.

I managed to run the feature_overview.ipynb with BeamNG.tech 0.29.1.0 on an Ubuntu host, so it does not seem the problem is universal. You can also try to obtain debug logs of the communication, that may help with further diagnosis:

from beamngpy.logging import set_up_simple_logging
import logging

set_up_simple_logging(level=logging.DEBUG, log_communication=True)

...
bng.open()
...

If you can provide these debug logs, that may help the diagnosis.

Have a nice day,

I just found out gridmap is not avaiable anymore. Have to use smallgrid but gives no error for it like map not found.

scenario = Scenario('gridmap', 'RADAR_demo', description='Spanning the map with a RADAR sensor')

I tired to run my code but sadly Shared Memory still not available under Linux?

import time

from beamngpy import BeamNGpy, Scenario, Vehicle, set_up_simple_logging
from beamngpy.sensors import Camera

def main():
    set_up_simple_logging()

    beamng = BeamNGpy('localhost', 64256)
    bng = beamng.open(launch=True)

    scenario = Scenario('smallgrid', 'Camera demo', description='Camera stream test')

    vehicle = Vehicle('ego_vehicle', model='etk800', license='RED', color='Red')

    scenario.add_vehicle(vehicle)
    scenario.make(bng)

    bng.settings.set_deterministic(60) # Set simulator to 60hz temporal resolution

    bng.scenario.load(scenario)
    bng.ui.hide_hud()
    bng.scenario.start()

    # NOTE: Create sensor after scenario has started.
    cam1 = Camera(
        'camera1',
        bng,
        vehicle,
        is_using_shared_memory=True,
        pos=(-5, 0, 1),

        is_render_annotations=False,
        is_render_depth=False,
        near_far_planes=(0.1, 1000),
        resolution=(3840, 2160),
        requested_update_time=0.05)

    t_last = 0.0
    for _ in range(10000):
        time.sleep(0.015)
        readings_data = cam1.poll()
        t = time.time()
        dt = t - t_last
        t_last = t
        print("time since last poll (s): ", dt)

    cam1.remove()
    bng.close()

if __name__ == '__main__':
    main()

Tired to use without it.

Attach is not supported?

Thanks!

Hi, unfortunately, shared memory is still not supported on Linux hosts, the same holds for the Camera sensor. It is on the roadmap, but it goes hand-in-hand with the stabilization of the Linux version as a whole.
