2022-09-02 13:56:39 浏览数 (1)

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

用法:

代码语言:javascript复制
torch.is_tensor(object) 

参数

  • object:这是要测试的输入张量。

返回:它返回True或False。

让我们借助几个示例来了解这个概念: 范例1:

代码语言:javascript复制
# 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:

代码语言:javascript复制
1
4
6
9
[torch.FloatTensor of size 4]
True

范例2:

代码语言:javascript复制
# 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:

 1.7367 -1.1454 -1.4369 -0.9856 -0.9076  0.6267
[torch.FloatTensor of size 4x6]
True
