torch_cumprod.RdCumprod
Arguments
- self
(Tensor) the input tensor.
- dim
(int) the dimension to do the operation over
- dtype
(
torch.dtype, optional) the desired data type of returned tensor. If specified, the input tensor is casted todtypebefore the operation is performed. This is useful for preventing data type overflows. Default: NULL.
cumprod(input, dim, out=NULL, dtype=NULL) -> Tensor
Returns the cumulative product of elements of input in the dimension
dim.
For example, if input is a vector of size N, the result will also be
a vector of size N, with elements.
$$ y_i = x_1 \times x_2\times x_3\times \dots \times x_i $$
Examples
if (torch_is_installed()) {
a = torch_randn(c(10))
a
torch_cumprod(a, dim=1)
