PyTorch Issue: Inconsistent Randomness Across Devices with Deterministic Algorithms
rice_fry · x · 2026-08-25
A PyTorch GitHub Issue (#84234) highlights that random number generation remains inconsistent across different GPUs even when usedeterministicalgorithms is enabled.
The issue argues that as a research platform, PyTorch should support reproducible results across different devices (CPU or physical GPU) given the same seed, PyTorch version, and CUDA version. The current inconsistency hinders experiment reproducibility.
