title: how to solve array must not contain infs or nans
body: <pre><code>fa = FactorAnalyzer(rotation = None,n_factors=5)
  fa.fit(dat)
  print(pd.DataFrame(fa.get_factor_variance(),index=['Variance','Proportional Var','Cumulative Var']))
  </code></pre>
  <p>I tried this code and gets the error as array must not contain nulls or infs.</p>
  <p>I checked for nulls and infs but there were no nulls or infs shown.
  So how can I solve this ?</p>
