title: "Values" object has no attribute "save"
body: <p>I am trying to work with the code below. However it is a written code by my professor and also in python2 (I already made quite some changes). I use python 3.8.5.</p>
  <p>When I try to run the code it yield me the Attribute Error below. Trying to adapt it by changing it the syntax or shorten up to save did not work and I also do not came across any reference of <strong>save</strong> in the web.</p>
  <pre class="lang-py prettyprint-override"><code>def __init__(self, options):
  
          self.save_each = options.save_each
  
          self.origin_dir = &quot;NET-%s-%s-%s&quot;%(options.currency, options.heuristic, options.epoch)
          if options.save_each is not None:
              self.origin_dir += &quot;_%s&quot;%options.save_each
  </code></pre>
  <pre><code>File &quot;comp-1-network_centrality.py&quot;, line 31, in __init__
      self.save_each = options.save_each
  AttributeError: 'Values' object has no attribute 'save_each'
  </code></pre>
  <p>Looking forward to help.</p>
