Runtime error: about badslam

[ishanivyas]

Hi I am having this error while running the dataset:

gui_main_window.cc:1600 INFO| Read dataset with 643 frames
QEGLPlatformContext: Failed to create context: 3009
QOpenGLWidget: Failed to create context
QEGLPlatformContext: Failed to create context: 3009
QOpenGLWidget: Failed to create context
QEGLPlatformContext: Failed to create context: 3009
QOpenGLWidget: Failed to create context

[puzzlepaint]

Googling the error message QEGLPlatformContext: Failed to create context: 3009 suggests that this might be due to old graphics hardware.

[ishanivyas]

Ok I will look into it. Thanks.

@puzzlepaint Now I am having this issue:

libGL error: No matching fbConfigs or visuals found

[puzzlepaint]

This seems wrong: libGL error: failed to load driver: swrast, since that sounds like it is trying to load a software rasterizer. Which graphics card does your PC have? Is the driver for it installed properly?

[ishanivyas]

when I run nvida-smi command on my container. I got this error:

[puzzlepaint]

This looks like normal output to me rather than an error (apart from the fact that there seems to be no application listed with any GPU usage - for me, this lists for example /usr/bin/X). Thus, in case other OpenGL applications are working fine with that setup in the container, then I probably can't help. I have never tried to run the application with more than one GPU installed, no idea whether it handles that case properly.

[ishanivyas]

I have removed older GPU and kept it NVIDIA-SMI 430.26 Driver Version: 430.26 CUDA Version: 10.2.
I am not able to run any OpenGL application on my container. I am working on it to putting debugger in code. Let you know if I make any progress. Thank you for your time and help!

[ishanivyas]

Any insight on it?

[puzzlepaint]

This seems to go wrong in some Qt-internal place. There is probably nothing that BAD SLAM can do about it. If you can't run any OpenGL application with your setup as you wrote in your previous post, then this setup is the problem.

[ishanivyas]

@puzzlepaint I fixed the issue with OpenGL on host system. I can run glxgear on container. But now I am getting the error "Segmentation fault (core dumped)". Is it build.sh file for badslam available for? Not sure why I am having still trouble.

[puzzlepaint]

Good that OpenGL works now. Unfortunately, "Segmentation fault (core dumped)" is a very generic error message that does not give any useful hint as to why the program crashed. At a minimum, a gdb backtrace would be required to make some guess.

[ishanivyas]

Thank you for your response!

[puzzlepaint]

Thank you for the backtrace. The program crashes at /home/ubuntu/badslam/libvis/src/libvis/shader_program_opengl.cc:84, which is the last line in this block:

  CHECK(shader_name != nullptr) << "Unknown shader type.";
  
  *shader_name = glCreateShader(shader_enum);

Since the first line in this block ensures that shader_name is not nullptr, the only way this can go to null is if glCreateShader is null. glCreateShader is a macro that expands to GLEW_GET_FUN(__glewCreateShader). I guess that if this returns null, GLEW is probably not initialized correctly.

This is weird, since in BadSlamRenderWindow::Initialize(), GLEW is initialized as follows:

  GLenum glew_init_result = glewInit();
  CHECK_EQ(static_cast<int>(glew_init_result), GLEW_OK);

So if there was an error there, the program should abort there. Maybe GLEW doesn't report the error there for some reason.

I think that this is as much as I can diagnose from here. For some reason, GLEW doesn't work correctly, but I don't know what the reason is.

Hi @puzzlepaint,

I am trying to use AppImage binary for windows. We have correct version cuda and driver install for windows. But when we run auto_tune_parameter.py file it throws us error saying "cuda 8 driver version is insufficient for cuda runtime version"

Could you please direct us? Do you have build.sh file to run on ubuntu?

Regards,
Ishani

[puzzlepaint]

• The AppImage binary is for Linux, not Windows.
• Googling the CUDA error message suggests that this may be due to not having a recent graphics driver version installed ( https://stackoverflow.com/questions/41409842 ).
• There is no automatic build script file.

[ishanivyas]

@puzzlepaint Thank you for your help! Sorry it was my mistake in the previous message. I have tried .exe file for windows 10 and AppImage binary file for Linux (18.04).
Windows 10 has latest driver.

[BinuxLiu]

About the original question

I solved this problem by re-install the graphics driver.
I used to install the driver manually.
Although I can use 'nvidia-smi', my Linux information shows llvm.
I uninstalled it and automatically installed the driver through Linux. This error is gone.
I've experimented many times, and it's true!
