# PyTorch torch.cuda.manual_seed Function * * * PyTorch torch Reference Manual `torch.cuda.manual_seed` is a function in PyTorch for setting the random seed for CUDA operations. It sets the random seed for the current CUDA device to ensure reproducibility of CUDA operations. ### Function Definition torch.cuda.manual_seed(seed) * * * ## Usage Example ## Example import torch # Set CUDA random seed if torch.cuda.is_available(): torch.cuda.manual_seed(42) x = torch.randn(3,3).cuda() print(f"Random tensor on CUDA: {x}") # Same seed produces same result torch.cuda.manual_seed(42) y = torch.randn(3,3).cuda() print(f"Random tensor with same seed: {y}") else: print("CUDA not available") * * * PyTorch torch Reference Manual PyTorch Data Transformations PyTorch torch.nn Reference Manual [Byte Ark Coding Plan supports Doubao, GLM, DeepSeek, Kimi, MiniMax and other mainstream large models, officially supplied and stable.
