Python – PyTorch is_tensor() 方法

如果传递的对象是 PyTorch 张量,PyTorch torch.is_tensor()方法返回 True。

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.FloatTensor([1, 4, 6, 9])
print(a)
  
# Applying the is_tensor function and 
# storing the result in 'out'
out = torch.is_tensor(a)
print(out)

输出:

1
 4
 6
 9
[torch.FloatTensor of size 4]
True

示例 2:

# Importing the PyTorch library 
import torch 
    
# A constant tensor of size n
a = torch.randn(4, 6)
print(a)
  
# Applying the is_tensor function and 
# storing the result in 'out'
out = torch.is_tensor(a)
print(out)

输出:

0.7491 -1.5987 -0.9733  0.0436 -0.3093  2.0007
 0.5679 -0.0092 -0.2573  0.9173  2.9849 -2.0159
-1.9215 -0.9131 -0.8244  0.4160 -0.3855  0.7033
 1.7367 -1.1454 -1.4369 -0.9856 -0.9076  0.6267
[torch.FloatTensor of size 4x6]
True
