title: No module named 'pandas.core.internals.managers'; 'pandas.core.internals' is not a package in Anaconda
body: <p>Trying to read a pickle file and store the data in an array. I keep running into an error with Pandas package, although my current Pandas is the latest version at 25.2. My python package is also at version 3.6.9.</p>
  
  <p>I updated Pandas in the Anaconda Environment to 25.2 as other links have suggested doing, but still run into the same problem.</p>
  
  <pre><code>import pickle
  
  file = open('sample.pkl', 'rb')
  data = pickle.load(file)
  </code></pre>
