title: How to quantize all nodes except a particular one?
body: <p>I am using <code>tensorflow</code> Graph Transform Tool to quantize the graph using</p>
  <pre><code>input_names = [&quot;prefix/input&quot;]
  output_names = [&quot;final_result&quot;]
  
  
  transforms1 = [&quot;strip_unused_nodes&quot;,&quot;fold_constants(ignore_errors=true)&quot;,  &quot;fold_batch_norms&quot;,  &quot;fold_old_batch_norms&quot;,&quot;quantize_weights&quot; ]
  
  transformed_graph_def = TransformGraph(graph.as_graph_def(), input_names,output_names, transforms1)
  </code></pre>
  <p>I use the option <code>quantize_weights</code> to quantize the weights in graph, I know that certain nodes can remain unquantized by changing threshold <code>minimum_size</code> in <code>quantize_weights</code>, so leaving some nodes unquantized is certainly possible.</p>
  <p>I want to quantize the weights of all nodes except a particular node with the name K or a set of nodes that have a name in K(set). How can this be achieved?</p>
