Apollo 9.0, EigenMatrix Problem

[ernestshun]

ubuntu terminal run: cyber_launch start modules/perception/launch/preception_camera_single_stage.launch
get the problem:

[ernestshun]

find it is reason of build_dbg

[daohu527]

Compilation options should not affect alignment. So I suspect it's a problem with the code

[Michael-Fuu]

I also use buld_dbg, and get same problem. My GPU is V100, Driver Version: 460.32.03 CUDA Version: 11.2. When I use: cyber_launch start modules/perception/launch/perception_camera_multi_stage.launch, most of the time I get problem, but a few time I can run normally.

Yes, if it succeeds occasionally, it is most likely that sometimes it can be aligned when the program is loaded, and sometimes it cannot. I will look at buld_dbg in detail and then reply.

It seems don't like a build_dbg problem, I tried to use build_gpu_opt and build_gpu later, getting same problem and can't success to start perception module by perception_camera_multi_stage.launch or perception_camera_single_stage.launch.

@Michael-Fuu You need to look at the specific reasons. Because there are many possible causes of this problem.

Can you further confirm core_dump?

yes, I use gdb /apollo/bazel-bin/cyber/mainboard/mainboard data/core/core_mainboard.3578 to check details(core_mainboard.3578 is from running cyber_launch start /apollo/modules/perception/launch/perception_camera_single_stage.launch),here is the result:

Do you have any advice? @daohu527
