Python wrappers
Public Python APIs implemented by this engine symbol.Vertically stack a sequence of tensors.
Equivalent to NumPy vstack: 1-D inputs of length N are promoted to
row vectors and stacked into a 2-D tensor of shape (len(xs), N);
inputs with rank >= 2 are concatenated along axis 0.
See Also
hstack_op, stack_op.
Parameters
xsvector<TensorImplPtr>Non-empty list of tensors. For rank >= 2, every dim except axis 0 must agree; for 1-D inputs, lengths must agree.
Returns
TensorImplPtrVertically stacked tensor with rank max(2, input_rank).
