@jrpowers Hi,I was struggled into a wired error seems related to gtsam when I run the python ./examples/slam_demo.py --dataset_dir=./datasets/Replica/office0 --dataset_name=nerf --buffer=100 --slam --parallel_run --img_stride=2 --fusion='nerf' --multi_gpu --gui demo the output is shown below: Running with GPUs: 0,1 Running pipeline in parallel mode.

I have the same problem, have you solve this problem?

I'm sorry, but I am no longer working on this project. If you discover a solution later on, I would be interested in giving it another attempt.
