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。
exp方法

让我们通过几个例子来看看这个概念:
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]
 2.8667
 0.1451
 1.8949
 0.4715
 2.4925
 1.4915
[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:

1
 4
 6
 3
[torch.FloatTensor of size 4]
   2.7183
  54.5981
 403.4288
  20.0855
[torch.FloatTensor of size 4]
