首先导包：

import torch

save_torch = torch.Tensor([[1, 2, 3, 4],
                           [2, 34, 5, 6]])

保存 tensor

torch.save(save_torch, 'test_save_tensor.pt')

读取 tensor

load_torch = torch.load('test_save_tensor.pt')

完整测试代码

import torch

save_torch = torch.Tensor([[1, 2, 3, 4],
                           [2, 34, 5, 6]])
print(save_torch)
torch.save(save_torch, 'test_save_tensor.pt') # 保存
load_torch = torch.load('test_save_tensor.pt') # 读取
print(load_torch)
