tf.keras.backend.ones

TensorFlow 1 version View source on GitHub

Instantiates an all-ones variable and returns it.

tf.keras.backend.ones(
    shape,
    dtype=None,
    name=None
)

Arguments:

  • shape: Tuple of integers, shape of returned Keras variable.
  • dtype: String, data type of returned Keras variable.
  • name: String, name of returned Keras variable.

Returns:

A Keras variable, filled with 1.0. Note that if shape was symbolic, we cannot return a variable, and will return a dynamically-shaped tensor instead.

Example:

<pre class="devsite-click-to-copy prettyprint lang-py">
<code class="devsite-terminal" data-terminal-prefix="&gt;&gt;&gt;">from keras import backend as K</code>
<code class="no-select nocode">    &gt;&gt;&gt; kvar = K.ones((3,4))</code>
<code class="no-select nocode">    &gt;&gt;&gt; K.eval(kvar)</code>
<code class="no-select nocode">    array([[ 1.,  1.,  1.,  1.],</code>
<code class="no-select nocode">           [ 1.,  1.,  1.,  1.],</code>
<code class="no-select nocode">           [ 1.,  1.,  1.,  1.]], dtype=float32)</code>
</pre>
