title: can't load csv file in python3 with pandas
body: <p>Hi guys I don't know why but pandas really can't manage to load my csv file in my python code. The file is in the same folder of my python project, I'm working with tensorflow, theano, pandas, numpy and matplotlib libraries. 
  It's been 2 hrs and I tried uninstalling everything and reinstalling once again using the pip3 commands. I uninstalled tensorflow, pandas, theano, numpy, and even python2 and python3. Nothing. I also updated and upgraded my linux distro. useless. </p>
  
  <p>this is the error I keep getting when I execute the part of my code in the Spyder3 internal terminal:</p>
  
  <pre><code>    dataset = pd.read_csv('Churn_Modelling.csv')
  Traceback (most recent call last):

  <p>And this is the freaking line of code:</p>
  
  <pre><code>dataset = pd.read_csv('Churn_Modelling.csv')
  </code></pre>
