Python – PyTorch exp() 方法
PyTorch torch.exp()
方法在获取输入张量元素的指数后返回一个新张量。
Syntax: torch.exp(input, out=None)
Arguments
- input: This is input tensor.
- out: The output tensor.
Return: It returns a Tensor.
让我们通过几个例子来看看这个概念:
示例 1:
示例 1:
# Importing the PyTorch library
import torch
# A constant tensor of size n
a = torch.randn(6)
print(a)
# Applying the exp function and
# storing the result in 'out'
out = torch.exp(a)
print(out)
输出:
1.0532
-1.9300
0.6392
-0.7519
0.9133
0.3998

[torch.FloatTensor of size 6]
示例 2:
# Importing the PyTorch library
import torch
# A constant tensor of size n
a = torch.FloatTensor([1, 4, 6, 3])
print(a)
# Applying the exp function and
# storing the result in 'out'
out = torch.exp(a)
print(out)
输出:
