torch_det(self)

Backward through `det` internally uses SVD results when `input` is
not invertible. In this case, double backward through `det` will be
unstable in when `input` doesn't have distinct singular values. See
`~torch.svd` for details.

if (torch_is_installed()) {

A = torch_randn(c(3, 3))
torch_det(A)
A = torch_randn(c(3, 2, 2))

A$det()
