Airsim crashes during training #94

Ujwal2910 · 2019-10-17T14:25:58Z

The simulator has been crashing an awful lot of times. After i start the training, usually after 300 or 200 steps the simulator crashes. This was the last log after the crash -

this is happening at simloadlevel, it seems?
just checking if you're simloadlevel-ing after each episode?
or is the same as reported in #90 and #77?

Ujwal2910 · 2019-10-18T08:19:34Z

Yes, I am loading the level after each reset. Even #90 and #77 are almost the same but still, there has not been any solution provided.

@Ujwal2910 we just updated the binaries with a fix to these reset bugs. can you please re-download airsim.zip and let us know if it works now?

Yeah i tested that. The simulation still crashes giving the following log-

Also for reset i am using the following snippet-
` def reset(self):

    self.baseline_racer.stop_odometry_callback_thread()
    self.baseline_racer.reset_race()
    # self.baseline_racer = BaselineRacer(drone_name="drone_1", viz_traj=self.viz_traj,
    #                                viz_traj_color_rgba=[1.0, 1.0, 0.0, 1.0], viz_image_cv2=self.viz_image_cv2)
    # # self.baseline_racer.load_level(self.level_name)
    self.baseline_racer.start_race(self.race_tier)
    self.baseline_racer.initialize_drone()
    self.baseline_racer.takeoff_with_moveOnSpline()`

Is this fine and if not can you suggest me a different snippet to restart the episode?

madratman · 2019-10-22T17:56:58Z

@Ujwal2910 my bad.
We only updated the v1.0 / qualification binaries.
I just updated the v0.3 / training linux binaries https://github.com/microsoft/AirSim-NeurIPS2019-Drone-Racing/releases/tag/v0.3.0-linux

Please re-download AirSim.zip

Yeah, you don't need to update the pythonclient. just ensure it's airsimneurips v1.0

We havent been able to carry out a full training yet and the time is flying as the deadline approaches. Please resolve this issue so we can atleast train some models on the environment

We have fixed a couple more crash cases in the binaries. Please re-download and give them a try.

@Ujwal2910 can you give us a script to reproduce this?
I recommend using this function to reset the drones: https://github.com/madratman/AirSim-NeurIPS2019-Drone-Racing/blob/tests/one_drone_end_race_and_reset_called/baselines/repro_crash_one_drone_ends_race_and_reset_called.py#L7

I testing the current binaries with the script above and am not seeing any crashes.

def dummy_reset(baseline_racer, drone_names, tier):
    baseline_racer.airsim_client.simPause(True)
    baseline_racer.airsim_client.reset()
    for drone_name in drone_names:
        baseline_racer.airsim_client.enableApiControl(vehicle_name=drone_name)
        baseline_racer.airsim_client.arm(vehicle_name=drone_name)
    baseline_racer.airsim_client.simPause(False) # unpause sim to simresetrace works as it's supposed to
    baseline_racer.airsim_client.simResetRace()
    baseline_racer.airsim_client.simStartRace(tier=tier)

Hey @Ujwal2910. Any updates on this? Please see discussions in #77 and #104

Ujwal2910 · 2019-10-25T18:51:24Z

Hey @madratman, Thanks for the dummy_reset function. The simulator hasn't crashed at all the everything seems to be working completely fine. I can now finally start the traning.
Thanks.

madratman · 2019-10-25T22:04:14Z

Awesome, thanks for your patience Ujwal. Glad it's working now!

Ujwal2910 · 2019-11-14T05:17:59Z

could you update after looking into this?

Did you change anything when you say "started again"? See discussion here #123 (comment)
