Error when running room_camera_intersection

[juanhotencoding]

Hello

I am trying to reproduce the synthetic scene generation pipeline and I am running into an error after I have created the scene_descriptions.txt file where I move onto running the room_camera_intersection.

I get the following error:

terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_M_construct null not valid Aborted (core dumped)

update:

I am now getting a seg fault error when I try running: ./room_camera_intersection ../../../shapenetdata/ShapeNetCore.v2/ ../../../scenenetlayouts/ ../../scene_generator/build/scene_description.txt

Here is the error:

ShapeNet directory:../../../shapenetdata/ShapeNetCore.v2/ Layouts directory:../../../scenenetlayouts/ Input Scene Description:../../scene_generator/build/scene_description.txt Loading my scene Segmentation fault (core dumped)

Sorry, I did not see that I was not providing the full path to the SceneNet Layouts.

I am now at the point where I think I have successfully created the scene_descriptions.txt then I run the ./room_camera_intersection command but I do not get a scene_and_trajectory_description.txt to use on the renderer command.

I was able to get scene_and_trajectory_description.txt but when I try to render I get the following error:

RANDOM TEXTURE AND LIGHT NUMBER:41599928 .//render_info.log There are 1 devices terminate called after throwing an instance of 'optix::Exception' what(): Parse error (Details: Function "RTresult _rtProgramCreateFromPTXFile(RTcontext, const char, const char, RTprogram_api**)" caught exception: The supplied PTX requires at least one device with SM 61 or greater.) Aborted (core dumped)

It looks like the GPU you are using does not support the architecture version of the compiled PTX files. You can edit that in the CMakeLists.txt line: 18 to suit your GPU. Nvidia has a list here. If you click on 'CUDA-Enabled GeForce Products' and find your GPU and its 'Compute Capability' e.g. For a GTX 770 it has Compute Capability 3.0 for which you would use 30 as written below:

SET(CUDA_NVCC_FLAGS   "-arch=compute_30 -code=sm_30"  "--use_fast_math" "-O3" "-lineinfo" "-Xcompiler")

Thanks that was able to get me past that error. I am now running into an issue with the renderer terminating after throwing a 'CVD::Exceptions::Image_IO::UnsupportedImageSubType' how should I go about handling this?

Sorry for the delay, I have now managed to replicate this issue with some of the textures in ShapeNetCore.v2. The problem seems to be from the interlacing type in some of the png files. I think I've managed to fix it by converting all of the texture pngs using ImageMagick. Below is an example code you can run

find ./ShapeNetCore.v2 -type f -name "*.png" -exec convert -interlace none -define png:color-type=6 {} {} \;

Let me know if this fixes it, I'll add it to the README as well.

Do I need to convert all of the texture pngs using ImageMagick as well? Or do I just need to run the commands you provided?

Actually just running the command seemed to work. I get the following output though:

Is this something I should be worried about?

[jmccormac]

That command should convert all of them because of the find exec prefix. Those same warnings appeared for me also, but I checked an image before and after and it looked ok, so nothing to be too worried about - but let me know if there are any problems with it. Glad that seemed to work. I'll close this issue now.
