Python PyTorch – RandomHorizontalFlip() Function Last Updated : 23 Jul, 2025 Comments Improve Suggest changes Like Article Like Report In this article, we will discuss the RandomHorizontalFlip() Method in PyTorch Python. RandomHorizontalFlip() method RandomHorizontalFlip() method of torchvision.transforms module is used to horizontally flip the given image at a random angle with a given probability. This method accepts a PIL and tensor image as input. The tensor image is a PyTorch tensor with shape [C, H, W], where C represents the number of channels and H, W represents the height and width respectively. This method returns a horizontally flipped image and an original image if the probability P is 1 or 0 respectively, if P is in the range between 0 to 1 then P is the probability to return the horizontally flipped image. Syntax: torchvision.transforms.RandomHorizontalFlip(p)(img) Parameter: p: p is the probability of the image being flipped at a random angle.img: input image to be flipped. Returns: This method returns a randomly flipped image at a random angle. The below image is used for demonstration: Example 1: In this example, we flip an image using RandomHorizontalFlip() Method when the probability is 1. Python3 # import required libraries import torch import torchvision.transforms as T from PIL import Image # read input image from computer img = Image.open('a.png') # define a transform transform = T.RandomHorizontalFlip(p=1) # apply above defined transform to # input image img = transform(img) # display result img.show() Output: Example 2: In this example, we flip an image using RandomHorizontalFlip() Method when the probability is in the range of 0 to 1. Python3 # import required libraries import torch import torchvision.transforms as T from PIL import Image # read input image from computer img = Image.open('img.png') # define a transform transform = T.RandomHorizontalFlip(p=0.5) # apply above defined transform to # input image img = transform(img) # display result img.show() Output: Comment More infoAdvertise with us Next Article Python Tutorial - Learn Python Programming Language M mukulsomukesh Follow Improve Article Tags : Python Python-PyTorch Practice Tags : python Similar Reads Python Tutorial - Learn Python Programming Language Python is one of the most popular programming languages.
