After upgrading to Isaac SIM 4 version, RTX Lidar sensor is not working properly

[Julie_A]

I am currently using ISACC SIM to configure the LiDAR. I started using version 2023.1.1 and it works fine.

I also know that after Isaac SIM 4.0, some changes were made to the configuration files.

I also know that after Isaac SIM 4.0, some changes were made to the configuration files. However, when I used the built-in configuration file for testing, unfortunately there were some errors and I was unable to use it. The configuration file I am using is the case file “ov/pkg/isaac-sim-4.0.0/exts/omni. isaac. sensor/data/lidar_configs/NVIDIA/Simple_Sample_Solid_State. json”，He can be successfully created, but will encounter an error and crash during execution.

import omni.kit.commands
from pxr import Gf
import omni.replicator.core as rep
lidar_config = "Simple_Example_Solid_State.json"


_, sensor = omni.kit.commands.execute(
    "IsaacSensorCreateRtxLidar",
    path="/sensor",
    parent=None,
    config=lidar_config,
    translation=(0, 0, 1.0),
    orientation=Gf.Quatd(1,0,0,0),
)

render_product = rep.create.render_product(sensor.GetPath(), [1, 1])


annotator = rep.AnnotatorRegistry.get_annotator("RtxSensorCpuIsaacCreateRTXLidarScanBuffer")
annotator.attach(render_product)

writer = rep.writers.get("RtxLidarDebugDrawPointCloudBuffer")
writer.attach(render_product)

The error message is

I hope to receive some help to solve my confusion. I can’t find any reason.

[chsu8]

I too am having issues with the RTX lidar and radar sensors. I am using now isaac sim 4.5. This is my current setup:

Whether I am using the script editor and following rtx lidar sensor or the standalone scripts given by ./python.sh standalone_examples/api/isaacsim.util.debug_draw/rtx_lidar.py I continue to have the same error.

I believe this error occurs when building the render product in step 2.
# 2. Create and Attach a render product to the camera render_product = rep.create.render_product(sensor.GetPath(), [1, 1])

I have also tried to follow the solution given here to no avail.

It does seem that the PhysX lidar sensor works for me but I’d like to use a specific RTX sensor that is provided, i.e. the Hesai XT32. Thank you!

[zhengwang]

@chsu8 This example loads fine for me in Isaac Sim 4.5.

Here is my output of nvcc --version

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2022 NVIDIA Corporation

Could you please show yours as well?

[chsu8]

@zhengwang

Edit:
I also just tried to reinstall my driver to the latest production version driver

and i continue to get the same errors

[zhengwang]

I saw your cuda version is 11.5. Could you please try with a newer version?
Mine is 11.8. Your system supports up to 12.4.

[chsu8]

Rather confusing but I followed Cuda 11.8 download and my nvcc --version continues to say 11.5 but the standalone rtx lidar script works! Thank you!

[zhengwang]

You will need to update your path to the correct cuda version in ~/.bashrc and source it

export PATH=/usr/local/cuda-11.8/bin${PATH:+:${PATH}}

[felix.watine]

I also get the same issue ([omni.sensors.nv.lidar.lidar_core.plugin] CUDA Driver CALL FAILED at line 259: invalid resource handle) when running ./python.sh standalone_examples/api/isaacsim.util.debug_draw/rtx_lidar.py in isaacsim 4.5

I am using cuda 11.8
and my driver version is 535.183.01

.

Any idea where this comes from?

[zhengwang]

Hey @felix.watine. I tried the same example and it works fine for me.
What is your operation system? If it is ubuntu, what is your ubuntu kernel version (do uname -r)?

[felix.watine]

Hey @zhengwang , I am using ubuntu 22.04. Kernel version is 6.8.0-52-generic. As per Driver requirements I updated my driver to 535.216.01, but it is still not working.

.

[zhengwang]

@felix.watine
Could you please try the solution provided in Known Issues — Isaac Sim Documentation #19?
A similar issue is raised in this post: Cuda update broke Lidar in Issac sim

[felix.watine]

Hi @zhengwang, I tried this solution but it did not work for me. I up-graded my driver to 570.124.06 and now it works!
