title: how to parse csv with name value pairs as text cells with colon seperation
body: <p>believe it or not, i couldn't find anywhere an answer to this:
  i have csv files with the following format:</p>
  <pre><code>Epoch: 1 Loss: 164.0284653747 
  Epoch: 2 Loss: 164.0155072829
  Epoch: 3 Loss: 163.9634398650 
  Epoch: 4 Loss: 163.8925548714 
  Epoch: 5 Loss: 163.9922899258 
  </code></pre>
  <p>how can i use pandas.read_csv to parse correctly and get out a dataframe:</p>
  <p>epoch -------   Loss</p>
  <p>1  -------------164.0284653747</p>
  <p>2  -------------164.0155072829</p>
  <p>hope my illustration is clear enough, i just want a dataframe with 2 columns named epoch and loss and the corresponding values.</p>
