Witrynatorch.rsqrt¶ torch. rsqrt ( input , * , out = None ) → Tensor ¶ Returns a new tensor with the reciprocal of the square-root of each of the elements of input . Witryna用法: torch. log1p (input, *, out=None) → Tensor 参数： input(Tensor) -输入张量。关键字参数： out(Tensor,可选的) -输出张量。返回具有 (1 + input ) 自然对数的新张量。注意对于 input 的小值，此函数比 torch.log () 更准确例子： >>> a = torch.randn (5) >>> a tensor ( [-1.0090, -0.9923, 1.0249, -0.5372, 0.2492]) >>> torch. log1p (a) tensor ( [ …
