Autoware runtime manager lidar_euclidean_cluster_detect clip_min_height parameter unable to take float values

edit

@syigzaw Thanks for looking into the cause of this issue! This sounds like a great opportunity for your first contribution to a major open-source project! As for saving the files while exiting/entering the Docker container, I suggest using the "base" docker container for Autoware (which just has the Linux environment and all dependencies installed) instead of the "full" docker container for Autoware (which also includes the pre-built source code). Here are some instructions which I will add to the Docker section of the Wiki for using the "base" container:

1. Create a workspace on your machine for working with the code.

   a. cd ~

   b. mkdir -p autoware.ai/src

2. Clone the Docker repository.

   a. git clone https://gitlab.com/autowarefoundation/autoware.ai/docker

   b. cd docker/generic

3. Use the run.sh script to enter the base Docker container without Autoware.ai included, mounting the provided folder into the Docker container in the /home/autoware/Autoware folder.

   a. ./run.sh -b $HOME/autoware.ai

4. Download and build the Autoware.ai source code inside the container.

   a. cd Autoware

   b. wget -O autoware.ai.repos "https://gitlab.com/autowarefoundation/autoware.ai/autoware/raw/master/autoware.ai.repos?inline=false" Note: If you want to use a different version of Autoware than master, replace master in the URL above with the version (e.g. 1.13.0).

   c. vcs import src < autoware.ai.repos

   d. colcon build

After you have completed the above instructions, you will have a workspace on your host machine in $HOME/autoware.ai which has been built by colcon and can be modified without losing your changes. Using the above ./run.sh command will also make that workspace available in the Docker container.

If you want to make a Merge Request to fix this issue, make a fork of the utilities repository on Gitlab. After that, delete the autoware.ai/src/autoware/utilities folder in your workspace, edit autoware.ai.repos to have the utilities repository point to your fork, then run the vcs import command again inside Docker. This will use your fork instead of the official one for the utilities repository. Once you have fixed the file and committed it to your fork, create a merge request back to the Autoware repository and the maintainers will review and merge it!
