Hi, thanks for interested in our work!
Could you try cutting the DataLoader’s num_workers to 0 or 1 and see if the error disappears?
If the problem persists, our 4D-GS reconstruction code is built on the official repo (https://github.com/fudan-zvg/4d-gaussian-splatting); their issues page may already have a fix or workaround.
