tensorflow:: ops:: Stack

Packs a list of N rank- R tensors into one rank- (R+1) tensor.

Summary

Packs the N tensors in values into a tensor with rank one higher than each tensor in values , by packing them along the axis dimension. Given a list of tensors of shape (A, B, C) ;

if axis == 0 then the output tensor will have the shape (N, A, B, C) . if axis == 1 then the output tensor will have the shape (A, N, B, C) . Etc.

For example:

# 'x' is [1, 4]
# 'y' is [2, 5]
# 'z' is [3, 6]
pack([x, y, z]) => [[1, 4], [2, 5], [3, 6]]  # Pack along first dim.
pack([x, y, z], axis=1) => [[1, 2, 3], [4, 5, 6]]

This is the opposite of unpack .

Args:

• scope: A Scope object
• values: Must be of same shape and type.

Optional attributes (see Attrs ):

• axis: Dimension along which to pack. Negative values wrap around, so the valid range is [-(R+1), R+1) .

Returns:

• Output : The packed tensor.
