4. zed sdk version:

ZED_SDK_Ubuntu20_cuda11.5_v3.7.1.run

Myzhar · April 6, 2022, 8:03am

Hi @haydenzhourepo
we have not tested the ZED SDK on Ubuntu 21.10, maybe OpenGL is in a different version with respect to Ubuntu 20.04 that is not compatible.

Another reason for this kind of error is the use of the machine by remote (i.e. ssh), is this your case?

haydenzhourepo · April 7, 2022, 3:14am

@Myzhar Thanks for your replay . I am not use remote machine with ssh, and i found another problem when i test exemple “depth-sensing”

i found it will thorw segment fault when call cudaGraphicsMapResources function

void PointCloud::initialize(sl::Resolution res) {
  glGenBuffers(1, &bufferGLID_);
  glBindBuffer(GL_ARRAY_BUFFER, bufferGLID_);
  glBufferData(GL_ARRAY_BUFFER, res.area() * 4 * sizeof(float), 0, GL_DYNAMIC_DRAW);
  glBindBuffer(GL_ARRAY_BUFFER, 0);

  checkError(cudaGraphicsGLRegisterBuffer(&bufferCudaID_, bufferGLID_, cudaGraphicsRegisterFlagsNone));

  shader_ = Shader(POINTCLOUD_VERTEX_SHADER, POINTCLOUD_FRAGMENT_SHADER);
  shMVPMatrixLoc_ = glGetUniformLocation(shader_.getProgramId(), "u_mvpMatrix");

  matGPU_.alloc(res, sl::MAT_TYPE::F32_C4, sl::MEM::GPU);

  checkError(cudaGraphicsMapResources(1, &bufferCudaID_, 0));
  checkError(cudaGraphicsResourceGetMappedPointer((void**) &xyzrgbaMappedBuf_, &numBytes_, bufferCudaID_));
}

checkError(cudaGraphicsMapResources(1, &bufferCudaID_, 0));

this function always error, i wonder how can i fix this problem?

Myzhar · April 7, 2022, 1:36pm

As I told you on the previous reply,

“we have not tested the ZED SDK on Ubuntu 21.10, maybe OpenGL is in a different version with respect to Ubuntu 20.04 that is not compatible.”

Flash · April 8, 2022, 7:52pm

I was having the same issue when I was using a remote desktop. When I try to run it on the host computer it works fine.

Myzhar · April 15, 2022, 3:37pm

@Flash In this case it can be a different problem.
What error message are you getting precisely?

kkoe2 · April 15, 2022, 9:47pm

I have the same issue, but I am on Ubuntu 20.04

Can you try to put the prefix MESA_GL_VERSION_OVERRIDE=3.3 before calling the ZED_Depth_Viewer command?

i.e. $ MESA_GL_VERSION_OVERRIDE=3.3 ZED_Depth_Viewer

Thanks @Myzhar,
It didn’t fixed the problem, below is the error I got.

What is the output of the command $ prime-select query?
Can you try to force the OS to use the Nvidia GPU by setting $ sudo prime-select nvidia and rebooting?

The original output said on-demand. Switching to the nvidia resulted in the following

In order to switch to nvidia I had to clean up my boot partition but then the output of the primary-select query was nvidia and the depth viewer worked!

Hello! I also met this problem.
ubuntu20.04
cuda 11.6
cudnn 8.4
nvidia-smi 510
and I also couldnn’t open the depth camera

Hi @moyodancer,
I did change prime-select to Nvidia but didn’t clean up the boot partition. Can I know how to clean up the boot partition and what does it do?

moyodancer · April 21, 2022, 8:35pm

sudo apt-get autoremove --purge will clean up unneeded kernals in your /boot partition. I only had to do this because sudo primary-select nvidia initially failed.

Hello! Did you solve this question, when I prime-select query, it said nvidia.

For me prime-select query says Nvidia but it still fails.

The problem with my new notebook after I apply primary-select nvidia, it just hangs after reboot
