ERROR: cannot launch node of type [dvo_benchmark/benchmark]: can't locate node [benchmark] in package [dvo_benchmark]

[lim0606]

Hi, I'm a newbie on both SLAM with RGB-D sensors and ROS.

I installed ROS indigo on Ubuntu 14.04, and successfully compiled dvo_slam with its jade_devel branch.

I got an error from ros when I tried to run the benchmark by following https://github.com/tum-vision/dvo_slam/issues/5. ERROR: cannot launch node of type [dvo_benchmark/benchmark]: can't locate node [benchmark] in package [dvo_benchmark]

I downloaded rgbd_benchmark_tools and dataset from https://github.com/jesusbriales/rgbd_benchmark_tools and https://vision.in.tum.de/data/datasets/rgbd-dataset/download, respectively.

I tried to run the program by running roslaunch dvo_benchmark benchmark.launch keep_alive:=true on the dataset folder where I also built assoc.txt.

The error message is as follows,

... logging to /home/jaehyun/.ros/log/1200da5c-c0cd-11e5-8841-7446a0bb7401/roslaunch-jaehyun-Workstation-9672.log

Is there anyone who can help me to run dvo_slam?

Thanks

Have you tried this before starting?

cd ~/catkin_ws/ source devel/setup.bash

[yvtheja]

@lim0606 , getting the same error as your. Seems like rosmake didn't go well. Did you find any solution?

Thanks :)

[anchuanxu]

I have encountered the same problem as you. Have you solved your problem?

[Ja721kai]

Pretty old thread.

Usually @buHtiGnioJ 's proposed solution solves this. Try:

echo "source ~/AAMR/catkin_ws/devel/setup.bash" >> ~/.bashrc   # if not already added
source ~/.bashrc

This link might also help you to setup your environment: http://wiki.ros.org/melodic/Installation/Ubuntu

Furthermore I assume that you granted execution rights onto the file that contains your node with chmod +x my_node since that might be a rather common issue as well.
