pytorch
PyTorch中的flatten函数用于将张量展平为一维。在引用中的案例2中,通过使用torch.flatten函数将一个3x3x3的张量展平为一维。可以看到,在start_dim=0和end_dim=1的情况下,张量的形状从(3, 3, 3)变为(9, 3)。在引用中的案例3中,通过使用torch.flatten函数将一个3x3x3的张量展平为一维。在start_dim=1和end_dim=2的情况下,张量的形状从(3, 3, 3)变为(3, 9)。最后,在引用中的案例中,如果将flatten函数改为reshape函数,将会得到不同的结果。具体来说,将图片张量reshape为形状为(1, 1, 1, -1)的张量,并通过这个张量传递给Tudui模型进行处理。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
