title: What is the difference between variable_scope and name_scope?
body: <p>What is the difference between <code>variable_scope</code> and <code>name_scope</code>? The <a href="https://www.tensorflow.org/programmers_guide/variable_scope#names_of_ops_in_tfvariable_scope" rel="nofollow noreferrer">variable scope tutorial</a> talks about <code>variable_scope</code> implicitly opening <code>name_scope</code>. I also noticed that creating a variable in a <code>name_scope</code> automatically expands its name with the scope name as well. So, what is the difference?</p>
