WebWe can divide the process of image augmentation into four steps: Import albumentations and a library to read images from the disk (e.g., OpenCV). Define an augmentation pipeline. Read images from the disk. Pass images to the augmentation pipeline and receive augmented images. Step 1. Import the required libraries. Import Albumentations Webtorch.Tensor.copy_ Tensor.copy_(src, non_blocking=False) → Tensor Copies the elements from src into self tensor and returns self. The src tensor must be broadcastable with the self tensor. It may be of a different data type or reside on a different device. Parameters: src ( Tensor) – the source tensor to copy from
