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. WebPytorch提供了Dataset和Data Loader来帮助处理数据集。对于语义分割的训练数据，假设我们已经有了原始图像及对应的标签图像。为了训练网络模型，我们需要原始图像的Tensor数据，形状为（N，C, H, W）。. 其中N为样本数量，C为通道数量，H和W表示图像的像素高度 … Web简单来说就是把PIL.Image或ndarray从 (H x W x C)形状转换为 (C x H x W) 的tensor。 ...
