[Pytorch] torch tensor에서 numpy, numpy에서 torch tensor 변경/전환 방법

torch tensor -> numpy import torch torch_value = torch.randn(1,3) print(torch_value) # tensor([[0.5519, 0.1323, 0.1297]]) numpy_value = torch_value.numpy() print(numpy_value) # [[0.551902, 0.132319, 0.129740]] numpy -> torch tensor import torch import numpy as np numpy_value = np.ones(4) print(numpy_value) # [1. 1. 1. 1.] torch_value = torch.from_numpy(numpy_value) print(torch_value) # tensor([1..
