Dear master, I encountered the same problem as the web page https://giters.com/uzh-rpg/rpg_dvs_ros/issues/117. But I find that /opt/inivation/boost/ has been instead of /opt/boost-inivation/. The erroe is still displayed as follows:

Camera calibration file /home/zfl/.ros/camera_info/DAVIS-00000554.yaml not found.

And I try uninstall boost-inivation, then I can't connnect to zhe DAVIS 346.

Can you help me ? All this are done on ubuntu 18.04.

Hi, I am also getting the same error. I have tried the solution given in the web page but it did not work.

Is there anything that I can try? I am working on Ubuntu 20.04 by the way.

Actually I met the same problem, that is because you do not have a well-formed YAML file, all you need is to fix your calibration result into a suitable form like this. /// image_width: 346 image_height: 260 camera_name: DAVIS camera_matrix: rows: 3 cols: 3 data: [274.6631, 0, 168.47, 0, 274.59, 141.8423, 0, 0, 1] distortion_model: plumb_bob distortion_coefficients: rows: 1 cols: 5 data: [-0.4043, 0.2296, 0.0003377, 0.000391, -0.080294] rectification_matrix: rows: 3 cols: 3 data: [1, 0, 0, 0, 1, 0, 0, 0, 1] projection_matrix: rows: 3 cols: 4 data: [1, 0, 1, 0, 0, 1, 1, 0, 0, 0, 1, 0] /// Do not forget to move it to the right path like "/home/xxx/.ros/camera_info" by the way.
