issue

The demo starts and drone is also running, it seems. But the ue4_bridge is not publishing any image probably because it is not receiving anything from the game. But I do not understand why. I could provide more information if needed.

I started the game manually and found that it crashes upon start due to some error. "Could not create OpenGL 3.2 context, Bad Alloc (Insufficient resources for operation.)" following image has the error in more detail. issue2

Hi, Can you please run nvidia-smi in the command line, both for the host machine and in the game guest container (the one that shows the errors). paste the output of those commands.

ykhedar commented 6 years ago

The host machine's output is the following `Thu Dec 14 13:07:11 2017
+-----------------------------------------------------------------------------+ | NVIDIA-SMI 387.34 Driver Version: 387.34 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

On the guest machine I get this output Failed to initialize NVML: Driver/library version mismatch

Also the guest machine produce the following output for cat /proc/driver/nvidia/version NVRM version: NVIDIA UNIX x86_64 Kernel Module 387.34 Tue Nov 21 03:09:00 PST 2017 GCC version: gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) this output is the same as the host machine..Is it possible the driver is not installed in the guest docker image?

ykhedar commented 6 years ago

Btw I changed the graphics driver on the host machine a few times because of some other problems. I did this after building the docker images, is it possible that this is the reason for the problem?

orig74 commented 6 years ago

Yes, That's the issue. when you run the nvidia-smi in the docker container and in the host you should see the same result e.g. the same graphics driver. try to run the build script again.

ykhedar commented 6 years ago

You are correct. :) Thanks for the help. I am closing this issue.
