Webtorch.nansum(input, *, dtype=None) → Tensor Returns the sum of all elements, treating Not a Numbers (NaNs) as zero. Parameters: input ( Tensor) – the input tensor. Keyword Arguments: dtype ( torch.dtype, optional) – the desired data type of returned tensor. If specified, the input tensor is casted to dtype before the operation is performed. Webtorch.isfinite(input) → Tensor Returns a new tensor with boolean elements representing if each element is finite or not. Real values are finite when they are not NaN, negative infinity, or infinity. Complex values are finite when both their real and imaginary parts are finite. Parameters: input ( Tensor) – the input tensor. Returns:
