title: Plotting Cumulative Gains Curve in Python (ModuleNotFoundError: No module named 'scikitplot')
body: <p>I am quite new to data science and python. I am trying to plot the cumulative gains curve of a model I have built in Spyder (Python 3.6) using scikitplot. However, it keeps returning the error: ModuleNotFoundError: No module named 'scikitplot'.</p>
  
  <p>See below: </p>
  
  <pre><code>import scikitplot as skplt
  Traceback (most recent call last):
    File "&lt;ipython-input-17-1b8f6cd7465e&gt;", line 1, in &lt;module&gt;
      import scikitplot as skplt
  ModuleNotFoundError: No module named 'scikitplot'
  </code></pre>
  
  <p>I have tried using the following on anaconda prompt:</p>
  
  <pre><code>pip install -U scikit-learn scipy matplotlib
  </code></pre>
  
  <p>and</p>
  
  <pre><code>pip3 install -U scikit-learn scipy matplotlib
  </code></pre>
  
  <p>However, neither of these have worked. Results in anaconda prompt:</p>
  
  <pre><code>(base) C:\Users\johndoe&gt;pip install -U scikit-learn scipy matplotlib
