I encountered an error with UserWarning: resource_tracker: while using it, and I'm not sure what the reason is.

I successfully deployed the project on a 4090 computer. But when I ran it on a 3090 computer using the same method, I encountered the following error:
/home/timo/miniconda3/envs/nerfstudio/lib/python3.8/site-packages/multiprocess/resource_tracker.py:219: UserWarning: resource_tracker: There appear to be 3 leaked semaphore objects to clean up at shutdown
warnings.warn('resource_tracker: There appear to be %d '

The computer configuration for 4090 is as follows: R9-5900X+128G+4090.
The computer configuration for 3090 is as follows: I9-10900K+32G+3090.
The system was directly cloned, and I have corrected the error caused by the graphics card. However, I have never known the reason for the error in this multitasking tracker.

I hope the author who knows the reason can answer this question. Thank you very much for completing such a great project.

I got same issue when I train nerf-facto model. When I run SfM process by colmap, the error didn't appear.
