# Python – PyTorch abs() method

• Last Updated : 26 May, 2020

PyTorch `torch.abs()` method computes the element-wise absolute value of the given input tensor.

Syntax: `torch.abs(inp, out=None) ? Tensor`

Arguments

• inp: This is input tensor.
• out: This is optional parameter and is the output tensor.

Return: It returns a Tensor having absolute value of input inp.

Let’s see this concept with the help of few examples:
Example 1:

 `# Importing the PyTorch library ``import` `torch ``   ` `# A constant tensor of size 1 ``a ``=` `torch.FloatTensor([``-``15``]) ``print``(a) ``   ` `# Applying the abs function and ``# storing the result in 'b' ``b ``=` `torch.``abs``(a) ``print``(b) `

Output:

```-15
[torch.FloatTensor of size 1]
15
[torch.FloatTensor of size 1]
```

Example 2:

 `# Importing the PyTorch library ``import` `torch ``   ` `# A constant tensor of size n ``a ``=` `torch.FloatTensor([``15``, ``-``5``, ``3``, ``-``2``]) ``print``(a) ``   ` `# Applying the abs function and ``# storing the result in 'b' ``b ``=` `torch.``abs``(a) ``print``(b) `

Output:

``` 15
-5
3
-2
[torch.FloatTensor of size 4]
15
5
3
2
[torch.FloatTensor of size 4]
```
