<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.variable(np.random.random((2,3)))</code>
<code class="no-select nocode">    &gt;&gt;&gt; kvar_ones = K.ones_like(kvar)</code>
<code class="no-select nocode">    &gt;&gt;&gt; K.eval(kvar_ones)</code>
<code class="no-select nocode">    array([[ 1.,  1.,  1.],</code>
<code class="no-select nocode">           [ 1.,  1.,  1.]], dtype=float32)</code>
