How to Compute the Error Function of a Tensor in PyTorch Last Updated : 23 Jul, 2025 Comments Improve Suggest changes Like Article Like Report In this article, we are going to cover how to compute the error function of a tensor in Python using PyTorch. torch.special.erf() method We can compute the error function of a tensor by using torch.special.erf() method. This method accepts the input tensor of any dimension and it returns a tensor with a computed error function with the same dimension as the input tensor. The below syntax is used to compute the error function of a tensor. Syntax: torch.special.erf(input) Parameters: input: This is our input tensor. Return: This method returns a tensor with computed error function of input tensor. Example 1: The following program is to understand how to compute the error function of the 1D tensor. Python3 # import required libraries import torch # creating a 1D tensor tens = torch.tensor([-0.7336, -0.9200, -0.4742, -0.4470, -0.3472]) # print above created tensor print("\n Input Tensor:", tens) # compute the error function er = torch.special.erf(tens) # Display result print("\n After Computed Error function :", er) Output: Example 2: The following program is to know how to compute the error function of a batch of tensors. Python3 # import required libraries import torch # creating a batch of tensor tens = torch.tensor([[[0.8636, -0.4195, -0.4681], [0.1265, 1.2233, 0.1978], [1.1389, 0.3686, 1.2339]], [[1.6362, 0.6235, 1.2631], [0.3336, 1.5336, 1.3677], [0.5637, 1.3236, 0.2696]]]) # print above created tensor print("\n\n Input Tensor: \n", tens) # compute the error function er = torch.special.erf(tens) # Display result print("\n\n After Computed Error function: \n", er) Output: Create Quiz Comment M mukulsomukesh Follow 0 Improve M mukulsomukesh Follow 0 Improve Article Tags : Python Python-PyTorch Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 5 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 2 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 7 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 15+ min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 8 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Python | Build a REST API using Flask 3 min read How to Create a basic API using Django Rest Framework ? 4 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
