UnpackedDualTensor

class torch.autograd.forward_ad.UnpackedDualTensor(primal, tangent) [source]

Namedtuple returned by unpack_dual() containing the primal and tangent components of the dual tensor.

See unpack_dual() for more details.

count(value, /)

Return number of occurrences of value.

index(value, start=0, stop=9223372036854775807, /)

Return first index of value.

Raises ValueError if the value is not present.
