Failed to publish a correct camera_info topic

[mohammad-h-b]

Hi,

Thanks for developing and sharing your great tool.

I used docker to install the requirements. To start camera node, when running roslaunch dope camera.launch, I get this error:

Traceback (most recent call last):
  File "/root/catkin_ws/devel/lib/dope/camera", line 15, in <module>
    exec(compile(fh.read(), python_script, 'exec'), context)
  File "/root/catkin_ws/src/dope/nodes/camera", line 13, in <module>
    from camera_info_manager import CameraInfoManager
ModuleNotFoundError: No module named 'camera_info_manager'

Any idea?

Found #150 but don't know how to fix it. Should I modify the CMakeList.txt and build the docker from the scratch?

Can you give me the command to install that package manually? when I run apt-get update && apt install -y ros-noetic-camera-info-manager-py, I get the following error:

Hmm, you're right, it looks like camera_info_manager_py has not been released to noetic yet, so there is no package ros-noetic-camera-info-manager-py. I have no idea why the other guy in #150 said it worked.

From browsing the code, it looks like the python code is python3 compatible, so it should work on noetic. Please try just cloning https://github.com/ros-perception/camera_info_manager_py into your catkin workspace. You'll probably have to modify the Dockerfile and add a git clone https://github.com/ros-perception/camera_info_manager_py command.

Thanks for your answer.

I cloned https://github.com/ros-perception/camera_info_manager_py into my workspace but still it doesn't work :(

You have to modify the Dockerfile, as I said.

I just added RUN git clone https://github.com/ros-perception/camera_info_manager_py to the Dockerfile but get this error:

You are missing the RUN command.

Please see my updated post (I put RUN command).

I am currently running into the same issue but neither this issue nor the one mentioned helped me solve the problem. Where exactly in Dockerfile.noetic do I need to add the "RUN git clone https://..." command? Do I just add the git clone command somewhere or do I also have to switch directory with WORKDIR ${CATKIN_WS}/src/ before I can clone the repository?
