Witryna在for 循环里, 总共有三点操作: 调用了dataloader 的__iter__() 方法, 产生了一个DataLoaderIter; 反复调用DataLoaderIter 的__next__()来得到batch, 具体操作就是, 多次调用dataset的__getitem__()方法 (如果num_worker>0就多线程调用), 然后用collate_fn来把它们打包成batch.中间还会涉及到shuffle, 以及sample 的方法等, 这里就不多说了. Witryna4 lut 2024 · 一般来说PyTorch中深度学习训练的流程是这样的：. 创建Dateset. Dataset传递给DataLoader.
