title: Two versions of Pandas causing problems
body: <p>It appears that when I run <code>&gt;conda list</code>, I have two versions of <code>pandas</code> installed. </p>
  
  <pre><code>pandas                 0.23.4              py36h830ac7b_0
  pandas                 0.22.0              &lt;pip&gt;
  </code></pre>
  
  <p>I cannot run <code>import pandas</code> or <code>import pandas as pd</code> in my console (Anaconda - Spyder/Jupyter Notebook) to check the version, but I am getting errors thrown in a script related to <code>pandas</code>:  </p>
  
  <blockquote>
    <p>Traceback (most recent call last) ...<br>
    from pandas.errors import
    AbstractMethodError</p>
    
    <p>ImportError: cannot import name 'AbstractMethodError'</p>
  </blockquote>
  
  <p>I was going to do <code>&gt;conda update pandas</code> but it said that my <code>numpy</code> would be downgraded. That doesn't sound right! How do I fix this?</p>
