WebMar 29, 2024 · mini-batch 我们之前学BGD、SGD、MGD梯度下降的训练方法，在上面就运用了sgd的方法，不管是BGD还是SGD都是对所有样本一次性遍历一次，如果想提升，大致相当于MGD的方法：把所有样本分批处理，每批次有多少个样本（batch），循环所有样本循环多少轮（epoch）。 WebInstead of calling torch.rand (size).cuda () to generate a random tensor, produce the output directly on the target device: torch.rand (size, device=torch.device ('cuda')). This is applicable to all functions which create new tensors and accept device argument: torch.rand () , torch.zeros () , torch.full () and similar. Use mixed precision and AMP
