Research direction

Start with Pasted.text.20260908-131850.txt and the reported training setup: DeePMD-kit 3.1.2, PyTorch, dpgen, and SSHFS 3.7.3. Reproduce training on an SSHFS-mounted system and determine whether concurrent worker access causes the reported error; done means identifying a reproducible incompatibility or a confirmed external cause.

Bug summary

Hello There,

i am currently training a model using Deepmd 3.1.2 with dpgen and I am experiencing issue when training on a SSHFS mounted system. The reported error seems to have a problem regarding the PyTorch workers accessing the same file at the same time.
I have attached the complete message regarding the problem. I am wondering if this has something to do with the Deepmd 3.1.2 or the SSHFS 3.7.3?

DeePMD-kit Version

3.1.2
