The visualizer crashes about semantic_suma HOT 8 CLOSED

Thanks for using our code. This issue seems similar to #5. You may have a look.

Thanks for your reply.

I tried ./bin/visualizer ./config/default.xml. The rv::XmlError doesn't appear but I still get segmentation fault.

Also now sometimes the GUI opens for a small amount of time (less than a second) then it crashes.

As for the default.xml, I changed only the last line to

<param name="model_path" type="string">/home/ubi-comp/Downloads/darknet53</param>

Also the build of semantic_suma finishes with 3 warnings. I can post them here if they may add additional information.

There is another point that might be relevant.

Inside tensorrt-config.cmake of rangenet_lib the build was not able to find_library the components of TensorRT. So I had to manually add these two lines:

include_directories(/home/ubi-comp/Downloads/TensorRT-5.1.5.0/include)
link_directories(/home/ubi-comp/Downloads/TensorRT-5.1.5.0/lib)

And to comment out set(TENSORRT_FOUND OFF). This made rangenet_lib work properly.

Hi @MohamedAfifii,

Is there any update about this issue?

from semantic_suma.

The problem was mainly with the GTSAM version. I had to use version 4.0.0-alpha2.

Hi. I think I have the same problem about 'segmentation fault'. I have confirmed that my rangenet_lib works good and its result is identical to template.

Sometimes I also can reach the lines like this:

and sometimes there is some graphic window showed up but crashed quickly.

So my question is that is the version of GTSAM really important over here? I have the latest 4.0.2 installed in my system. Or am I missing something else? @Chen-Xieyuanli

Hey @Claud1234, I never encountered such a problem, but it seems there are also some reasons which may cause the crash. You may have a look at #5 and here

Okay. Thanks for reply first. I will solve my own problems here. The version of GTSAM exactly is the reason that result visualizer crashed. I had the latest one 4.0.2 before, everything works good after I downgrade it to 4.0.0-alpha-2.

Thanks for help anyway!
