NLP - 关于pytorch_nlp和pytorch的关系

1. 关于torch张量tensor

from __future__ import print_function
import torch

matrix = torch.randn(2,3)
print(type(matrix))
print(matrix.size())

matrix1 = torch.rand(2,3)
print(type(matrix1))
print(matrix1.size())

matrix2 = torch.FloatTensor([2,3])
print(matrix2)
print(type(matrix2))
print(matrix2.size())

输出：

<class 'torch.Tensor'>
torch.Size([2, 3])
<class 'torch.Tensor'>
torch.Size([2, 3])
tensor([2., 3.])
<class 'torch.Tensor'>
torch.Size([2])
