title: RuntimeError: variable_scope module_1/ was unused but the corresponding name_scope was already taken. How can i fix it
body: <p>i got this problem with elmo and tensorflow and i wanna fix it without downgrade. what should i do</p>
  <pre><code>`**CODE**
  import tensorflow_hub as hub
  import tensorflow as tf
  #Elmo
  elmo = hub.Module(&quot;https://tfhub.dev/google/elmo/2&quot;, trainable=True)
  
  # Provide input tensor and create embeddings
  input_tensor = [&quot;my birthday is the best day of the year&quot;]
  embeddings_tensor = elmo(input_tensor, signature=&quot;default&quot;, as_dict=True)[&quot;elmo&quot;]
  * here i got the problem *
  with tf.Session() as sess:
      sess.run(tf.global_variables_initializer())
      embeddings = sess.run(embeddings_tensor)
      print(embeddings.shape)
      print(embeddings) 
  `
