error loading <rosparam> file does not exist
I am facing a problem with loading a yaml file to robot_localization node. I am pretty sure of the path and the name of the file as there are multiple other parameters file and they all loaded just fine. I don't have a clue where this error comes from if anyone can help please do not hesitate. This the error when I launch:
RLException: error loading <rosparam> tag:

Are you sure
ekff.yamlis located where you think it is? In a terminal, could you navigate to where the file is, runpwdand compare it to the path listed in your error? The syntax for your node and rosparam look correct, but there may be some minor name differences causing the error. For instance, I have my yaml files located in aconfig/folder vs yourparam/.I already navigated to the file path through the terminal and it is already the same path. The param file was named config but i deleted it and created a new file and i named it differently. This approach worked out with someone who had the same error but it did not workout for me.
