Cannot build ros_deep_learning package on Jetson Nano

[gustav.a]

Hello everyone

I have a Jetson Nano running Ubuntu 18.04 with L4T 32.7.1. I have a Docker container running (from this ros2 foxy image ) ros2 foxy and I’ve gotten turtlesim to work along with my own package. However, I want to build the ros_deep_learning package and it does not want to build.

This is how I did:

cd ~/ros2_ws/src
git clone https://github.com/dusty-nv/ros_deep_learning
cd ~/ros2_ws
colcon build

But then it fails, this is a snippet:

--- stderr: camera_info_manager
/root/ros2_ws/src/ros-perception/image_common/camera_info_manager/src/camera_info_manager.cpp:46:10: fatal error: rcpputils/env.hpp: No such file or directory
 #include "rcpputils/env.hpp"
          ^~~~~~~~~~~~~~~~~~~
compilation terminated.

  22 packages not processed

It didn’t even try ros_deep_learning so I tried this:

colcon build --packages-select ros_deep_learning --symlink-install --event-handlers console_direct+

~/ros2_ws# colcon build --packages-select ros_deep_learning --symlink-install --event-handlers console_direct+
[2.722s] WARNING:colcon.colcon_core.verb:Some selected packages are already built in one or more underlay workspaces:
	'ros_deep_learning' is in: /root/ros2_ws/install/ros_deep_learning
If a package in a merged underlay workspace is overridden and it installs headers, then all packages in the overlay must sort their include directories by workspace order. Failure to do so may result in build failures or undefined behavior at run time.
If the overridden package is used by another package in any underlay, then the overriding package in the overlay must be API and ABI compatible or undefined behavior at run time may occur.

If you understand the risks and want to override a package anyways, add the following to the command line:
	--allow-overriding ros_deep_learning

This may be promoted to an error in a future release of colcon-core.

There seems to be some sort of issue with jetson-inference? It was already installed in the image but is still causing problems. I tried to update Jetpack to see if it was that but it didn’t fix anything.

Grateful for any help!

/usr/local/include/jetson-inference/tensorNet.h:58:19: error: ‘Dims3’ in namespace ‘nvinfer1’ does not name a type
 typedef nvinfer1::Dims3 Dims3; 

I tried to update Jetpack to see if it was that but it didn’t fix anything.

Hi @gustav.a, did you start your container with --runtime nvidia or is your default docker runtime set to nvidia? https://github.com/dusty-nv/jetson-containers#docker-default-runtime

Due to the missing TensorRT structs that you are getting errors on, I think those files aren’t being mounted into the container (which the nvidia runtime normally takes care of automatically).

It’s also possible that when you upgraded JetPack-L4T, it is messing with these being mounted into the container correctly. What’s your current version of L4T (you can check this with cat /etc/nv_tegra_release)? Does your L4T version match the version tag of the container you are running?

[gustav.a]

Hi @dusty_nv ! I took a new SD-card and flashed a L4T 32.6.1 Jetpack 4.6 image to it (drivers for the camera only went up to Jp4.6). I’ve now edited daemon.json with the extra line (I am unsure when in the process I did that on the other SD-card (32.7.2)), pulled foxy-pytorch-l4t-r32.6.1 but now I’m unsure about the docker run options. I am think about this right now:

docker run -it --net=host --env="DISPLAY" --volume="$HOME/.Xauthority:/root/.Xauthority:rw" --name ros2_container_4.6 -it dustynv/ros:foxy-pytorch-l4t-r32.6.1 /bin/bash

Anything that should be added/removed?

Thanks in advance!

[dusty_nv]

Although you are missing --runtime nvidia from that command line, it sounds like you have already set it as the default in your daemon.json. I would try either using the docker_run.sh script from jetson-containers, or using the docker run command that it does:

https://github.com/dusty-nv/jetson-containers/blob/be0dca3d19b30e64d129c92e93425c9ede40d65f/scripts/docker_run.sh#L113

I think by you specifying the container to run /bin/bash, it will override the ros_entrypoint.sh from the dockerfile (which sets the ROS environment)

[gustav.a]

Yes, I added “default-runtime”: “nvidia” in daemon.json before running :).

Alright, is it too late to not specify /bin/bash when doing docker exec <...>? I’ve always used it. Do I need to remove the container and run a new one from the same image, or is it enough to not do it in docker exec ?

Also, I’m a bit confused regarding the difference between jetson-containers and the docker hub . I pulled an image from dustynv/ros at dockerhub, what would be the difference to git clone https://github.com/dusty-nv/jetson-containers (except for the fact that the docker images have specific installations)? You linked the docker_run.sh file from the github page, so I assume that’s something thats the same for both of them?

Edit: I looked in the file you sent and ran

sudo docker run -it --rm --network host -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix -v /tmp/.docker.xauth:/tmp/.docker.xauth -e XAUTHORITY=/tmp/.docker.xauth dustynv/ros:foxy-pytorch-l4t-r32.6.1

There were no complaints and the container started. However, I want to open a new terminal in the container with docker exec -u root -it <name_of_container> <something else than /bin/bash> but I don’t know what to put instead of /bin/bash. It says “docker exec requires at least 2 arguments”.

Edit#2: doing docker exec -u root -it <container_name> /ros_entrypoint.sh gives

sourcing      /opt/ros/foxy/install/setup.bash
ROS_ROOT  /opt/ros/foxy
ROS_DISTRO foxy

but then the terminal just returns to the host terminal and doesn’t enter the container…

I then did how I usually do with /bin/bash and tried video_viewer. The errors can be seen here:

I believe you can just do /bin/bash and manually run /ros_entrypoint.sh to source the ROS environment. Or if you did docker run without specifying a start-up command, I think it will have already been run (but not sure that will carry over to a new terminal session started with docker exec)

@gustav.a

Also, I’m a bit confused regarding the difference between jetson-containers and the docker hub

The jetson-containers github is the source dockerfiles, build scripts, and run scripts that was used to create the container images that are hosted on DockerHub. You can use the run script with images from DockerHub without having to rebuilt them. If desired, you can make changes to the Dockerfiles and rebuild the containers locally if you want.

@gustav.a

launch.substitutions.substitution_failure.SubstitutionFailure: launch configuration 'input_latency' does not exist

OK, there appears to have been a missing argument definition in one of the launch file includes, sorry about that. I have patched it in ros_deep_learning master in commit a58d69. Can you pull the latest repo and try again?

[gustav.a]

sorry about that.

No need to apologize! You’re being incredibly helpful!

Thanks! Your commit enabled ros_deep_learning to build without 1 package had stderr output: ros_deep_learning appearing, and I managed to run video_viewer. However, it got stuck in other errors:

This is where we get to the problem I have with my CSI Camera. It’s an e-CAM30_CUNANO from e-con Systems and after installing the provided drivers for L4T32.6.1 (natively on the Nano), it still does not appear as /dev/video*, there are no such files in either the native files or in the container. The camera itself works, since I’ve tried it on a different Nano (not developer version, and with a different setup, version etc) and it does indeed show a /dev/video0 when the camera is plugged in.

This problem has been active all last week and I’m in contact with the support regarding this issue. I believe that the containers running your images as well as the ros_deep_learning repo are now working as they should, it’s just that the camera itself won’t work with any program. I can’t even run nvgstcapture-1.0 outside of the container without it complaining that no camera is detected.

If you can see any possible fix from the errors that video_viewer returned, that would be amazing but as mentioned, I don’t think it’s your work that is causing the problem. Thanks so much for the help, I will get back with new information as it comes up.

Edit#1: Ran xhost +local:docker, reran the command and replaced the error messages with what it put out. Before it had problems with [OpenGL] failed to open X11 server connection., which is now gone.

Hi @gustav.a, glad that you got the packages building - yes, you are correct that since nvgstcapture-1.0 is unable to find your camera, then neither will video-viewer node. Perhaps it is some camera driver issue on that version of JetPack-L4T that you are running on that Nano.

[gustav.a]

Indeed. I contacted the manufacturers of the carrier board and they said that the current driver only supports cameras using IMX219, which my camera does not. I’m awaiting a response but currently the thing limiting me is the camera driver. I think we can close this now. Thanks for the help!
