在PyTorch中,你可以创建一个complex128类型的张量,并使用view_as_real来处理这个复数张量。view_as_real函数将复数张量转换为实数张量,它通过将复数张量的实部和虚部分别分开,将复数张量展平为一个由两部分组成的实数张量。 步骤: 创建一个complex128类型的张量。 使用view_as_real将复数张量转换为实数张量
.RandomCrop(a,b):在图像周围以b为大小填充,人为扩大,然后再按照a×a的大小裁剪 .ToTensor():将图像从PIL图像转换为PyTorch张量 .Normalize(mean=[mean], std=[std]):规范化,减去平均值mean,然后除以给定的标准差std 模型定义 class 模型名称(nn.Model): def __init__ (self,input_dim,output_dim): sup...
1. 导入必要的库 在开始之前,我们需要导入必要的库来使用PyTorch和处理复数数值: importtorch 1. 2. 创建复数张量 我们需要创建一个复数张量,以便进行模运算。在PyTorch中,我们可以使用torch.complex函数来创建一个复数张量。下面的代码将创建一个包含两个复数的张量: tensor_complex=torch.complex(torch.tensor([3.0...

Python PyTorch complex用法及代码示例本文简要介绍python语言中 torch.complex 的用法。用法:torch.complex(real, imag, *, out=None)→ Tensor参数: real(Tensor) -复张量的实部。必须是浮点数或双精度数。 imag(Tensor) -复张量的虚部。必须与 real 具有相同的 dtype。 关键字参数: out(Tensor) -如果输入是...
view_as_complex()仅支持具有torch.dtypetorch.float64和torch.float32的张量。输入的最后一个维度预计为size2。此外,张量的最后一个维度的stride必须为 1。所有其他维度的步幅必须是偶数。 例子: >>>x=torch.randn(4,2)>>>x tensor([[1.6116,-0.5772], ...
