sequence.sequence_length

   fn sequence_length(self: Array<Tensor<T>>) -> Tensor<u32>;

Returns the length of the input sequence.

Args

• self(Array<Tensor<T>>) - The input sequence.

Returns

The length of the sequence as scalar, i.e. a tensor of shape [].

Examples

Let's create new u32 Tensor with constant 42.

let mut sequence = ArrayTrait::new();

let mut shape = ArrayTrait::<usize>::new();
shape.append(1);
shape.append(2);

let mut data = ArrayTrait::new();
data.append(3);
data.append(1);

sequence.append(TensorTrait::new(shape.span(), data.span()));
