Removes dimensions of size 1 from the shape of a tensor. (deprecated arguments)
tf.compat.v1.squeeze(
input, axis=None, name=None, squeeze_dims=None
)
Warning: SOME ARGUMENTS ARE DEPRECATED: (squeeze_dims)
. They will be removed in a future version.
Instructions for updating:
Use the axis
argument instead
Given a tensor input
, this operation returns a tensor of the same type with
all dimensions of size 1 removed. If you don't want to remove all size 1
dimensions, you can remove specific size 1 dimensions by specifying
axis
.
>>> # 't' is a tensor of shape [1, 2, 1, 3, 1, 1]
>>> t = tf.ones([1, 2, 1, 3, 1, 1])
>>> print(tf.shape(tf.squeeze(t)).numpy())
[2 3]
Or, to remove specific size 1 dimensions:
>>> # 't' is a tensor of shape [1, 2, 1, 3, 1, 1]
>>> t = tf.ones([1, 2, 1, 3, 1, 1])
>>> print(tf.shape(tf.squeeze(t, [2, 4])).numpy())
[1 2 3 1]
Note: if input
is a tf.RaggedTensor
, then this operation takes O(N)
time, where N
is the number of elements in the squeezed dimensions.
input
: A Tensor
. The input
to squeeze.axis
: An optional list of ints
. Defaults to []
. If specified, only
squeezes the dimensions listed. The dimension index starts at 0. It is an
error to squeeze a dimension that is not 1. Must be in the range
[-rank(input), rank(input))
. Must be specified if input
is a
RaggedTensor
.name
: A name for the operation (optional).squeeze_dims
: Deprecated keyword argument that is now axis.A Tensor
. Has the same type as input
.
Contains the same data as input
, but has one or more dimensions of
size 1 removed.
ValueError
: When both squeeze_dims
and axis
are specified.
