RMADER has been tested with Ubuntu 20.04/ROS Noetic
The backend optimizer is Gurobi. Please install the Gurobi Optimizer, and test your installation typing gurobi.sh
in the terminal. Have a look at this section if you have any issues.
Then simply run this commands:
cd ~/ && mkdir ws && cd ws && mkdir src && cd src
git clone https://github.com/mit-acl/rmader.git
cd ..
bash src/rmader/install_and_compile.sh
The script install_and_compile.sh will install CGAL v4.12.4, GLPK and other ROS packages (check the script for details). It will also compile the repo. This bash script assumes that you already have ROS installed in your machine.
Install Docker using this steps, and remove the need of sudo
following these steps. Then follow these steps:
cd ~/ && mkdir ws && cd ws && mkdir src && cd src
git clone https://github.com/mit-acl/rmader.git
For Gurobi, you need to download gurobi.lic file from Gurobi Web License Manager (more info here). A gurobi.lic not obtained through WLS will not work on docker. Place your gurobi.lic in docker folder and execute these commands:
cd ./rmader/rmader/docker
docker build -t rmader . #This will probably take several minutes
Once built,
docker run --volume=$PWD/gurobi.lic:/opt/gurobi/gurobi.lic:ro -it rmader
Useful Docker commands
docker container ls -a #Show a list of the containers
docker rm $(docker ps -aq) #remove all the containers
docker image ls #Show a lis of the images
docker image rm XXX #remove a specific image
### lambda machine simulation
docker build -f rmader/rmader/docker/Dockerfile -t rmader .
docker run --cpus=48 --volume=/home/kkondo/rmader_project/rmader_ws/src/rmader/rmader/docker/gurobi.lic:/opt/gurobi/gurobi.lic:ro --volume=/home/kkondo/data:/home/kota/data -it rmader
Note: For a high number of agents, the performance of RMADER improves with the number of CPUs available in your computer.
roscd rmader && cd script && python run_rmader.py
(if you want to modify the parameters, you can do so in rmader.yaml
).
If you find the error:
“gurobi_continuous.cpp:(.text.startup+0x74): undefined reference to
`GRBModel::set(GRB_StringAttr, std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)'”
The solution is:
cd /opt/gurobi800/linux64/src/build #Note that the name of the folder gurobi800 changes according to the Gurobi version
sudo make
sudo cp libgurobi_c++.a ../../lib/
This package uses some C++ classes from the DecompROS repo (included in the thirdparty
folder).
