The functions below split an image tensor (B, C, H, W) into equal sized tiles (B, C, H, W) and then you can do stuff individually to the tiles in order to save memory. Then when rebuilding the tensor from the tiles, it uses masks to ensure that the tiles are seamlessly blended back together. egyptian shipWebApr 12, 2024 · PyTorch is an open-source framework for building machine learning and deep learning models for various applications, including natural language processing and machine learning.
