pytorch中tensor和Variable转换为numpy

1.pytorch中tensor的构建可以使用numpy:

import torch

import numpy as np

from torch.autograd import Variable

x_tensor=torch.Tensor(np.array([1,2,34]))

2.Variable的构建需要tensor

x_Variable=Variable(x_tensor)

3.tensor转变为numpy:

x_numpy=x_tensor.numpy()

4.Variable转变为numpy：

x_numpy=x_Variable.data.numpy()
