python设置随机数种子(numpy,pytorch,random)

为了保证代码能够复现，需要固定所有可能的随机数

import torch
import numpy as np
import randomdef seed_everywhere(seed):torch.manual_seed(seed)torch.cuda.manual_seed(seed)torch.cuda.manual_seed_all(seed)  # if you are using multi-GPU.np.random.seed(seed)  # Numpy module.random.seed(seed)  # Python random module.
