Hi! The cslam_experiments seems not to be in your path. Have you sourced the ROS 2 worskpace? source install/setup.bash
?
Hello, Thanks for your response.
Yes, I have sourced the ros2 workspace. and I am running this from /home/e/Swarm-SLAM/src/cslam_experiments/launch/dataset_experiments directory. What could be the possible reason for this problem?
The same situation. Did you solve this error, bro?
yes, I solved it. Do you have the same error?
yes, I solved it. Do you have the same error?
How could you solve it? I found I even met worse case, after I "colcon build", I ran "colcon test" then I found I could not find this file "Cannot find file: /root/Swarm-SLAM/build/gtsam/DartConfiguration.tcl" and the later process need some files of gtsam I did not have neither.
rebuild the gtsam with version 4.1.1 and after sudo make install, make sure you do "sudo ldconfig"
And for ROS 2 dependencies, execute these commands:
and then build again.. I hope it helps
after the build is successful, you need to download Graco dataset (first 3 ground sequences). Make sure you have installed teaser as you are working with LiDAR dataset: https://teaser.readthedocs.io/en/latest/installation.html#installing-python-bindings

It seems not because of this reason. the package 'cslam_experiments' is not in the ros2 work space
Sorry for the very late reply, I was on an internship and had no time for support. Few comments:
cslam_experiments
should be in the ros2 workspace. Look under install/
