Packs a list of N
rank-R
tensors into one rank-(R+1)
tensor.
tf.raw_ops.Pack( values, axis=0, name=None )
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.
# '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 | |
---|---|
values | A list of at least 1 Tensor objects with the same type. Must be of same shape and type. |
axis | An optional int . Defaults to 0 . Dimension along which to pack. Negative values wrap around, so the valid range is [-(R+1), R+1) . |
name | A name for the operation (optional). |
Returns | |
---|---|
A Tensor . Has the same type as values . |
