@MichaelJoker Sorry but I'm not actively maintaining the repo. Can you try with a stable GTSAM branch and see if it works?

MichaelJoker commented 4 years ago

@itzsid Ok, thanks, the newest one can work for me, by just doing some modifications.

itzsid commented 4 years ago

@MichaelJoker Thanks! It will be great if you can create a PR for the modifications you made.

@MichaelJoker I have the same error.How did you solve it?

itzsid commented 3 years ago

@treejustmoveon, Can you try the instructions given in the docker file here: https://github.com/CogRob/distributed-mapper/blob/master/distributed_mapper_core/docker/distributed_mapper/Dockerfile

You can directly use an uploaded docker image as well, for example: 

docker pull awilby/distributed_mapper:latest
docker run awilby/distributed_mapper --nrRobots 4 --dataDir ../../data/example_4robots/
