Removes dimensions of size 1 from the shape of a tensor.
tf.compat.v2.squeeze(
input, axis=None, name=None
)
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
.
For example:
# 't' is a tensor of shape [1, 2, 1, 3, 1, 1]
tf.shape(tf.squeeze(t)) # [2, 3]
Or, to remove specific size 1 dimensions:
# 't' is a tensor of shape [1, 2, 1, 3, 1, 1]
tf.shape(tf.squeeze(t, [2, 4])) # [1, 2, 3, 1]
Unlike the older op tf.compat.v1.squeeze
, this op does not accept a
deprecated squeeze_dims
argument.
Args | |
---|---|
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). |
Returns | |
---|---|
A Tensor . Has the same type as input .
Contains the same data as input , but has one or more dimensions of
size 1 removed.
|
Raises | |
---|---|
ValueError
|
The input cannot be converted to a tensor, or the specified axis cannot be squeezed. |
