Is it possible to load the parameters file while running?

Is it possible to load a parameter yaml file during runtime?

I have multiple parameter files that I would like to switch parameter file while running.

For example, I have

• setting1.yaml
• setting2.yaml

and at startup, setting1.yaml is loaded. (This can be configured in launch.py)

After that, I want to load setting2.yaml and apply parameters while running.

The ros2 version is eloquent.

I am using jetson and jetson's OS(Jetpack) is based on ubuntu18.04 so I cannot use foxy.

In the foxy manual, I found the following section.

6 ros2 param load You can load

parameters from a file to a currently running node using the command:

ros2 param load <node_name> <parameter_file>

https://docs.ros.org/en/foxy/Tutorial...

However, there is no mention of this in the eloquent manual, and in fact the command resulted in an error.

Any advice would be appreciated.
