title: Tensorflow get_variable function showing str object not callable
body: <pre><code>self.initializer = tf.random_normal_initializer(stddev=0.1)
  word_embedding_weight = tf.get_variable(&quot;word_embedding_weight&quot;, [self.number_of_embedding, self.embedding_dimension], tf.float32, self.initializer)
  </code></pre>
  <p>I'm trying to use the tf.get_variable function just like this but I get str object not callable error</p>
  <pre><code>TypeError: 'str' object is not callable
  </code></pre>
  <p>Can someone please help me here?</p>
