tensorplay.nn.utils.rnn.invert_permutation

tensorplay.nn.utils.rnn.invert_permutation(permutation: TensorBase | None) → TensorBase | None[source]

Returns the inverse of permutation.

This is useful for converting between sorted and unsorted indices in a PackedSequence.

Parameters:

permutation (Tensor, optional) – a 1-D tensor of indices to invert

tensorplay.nn.parameter.is_lazy

Returns whether param is an UninitializedParameter or UninitializedBuffer .

tensorplay.nn.utils.rnn.pack_padded_sequence

Packs a Tensor containing padded sequences of variable length.
