title: PyCharm cannot find module from pip install
body: <p>I installed the module with the command: <code>pip install matplotlib</code>. However, PyCharm does not find the module I installed.</p>
  <pre><code># importing the required module
  import matplotlib.pyplot as plt
  
  # x axis values
  x = [1,2,3]
  # corresponding y axis values
  y = [2,4,1]
  
  # plotting the points
  plt.plot(x, y)
  
  # naming the x axis
  plt.xlabel('x - axis')
  # naming the y axis
  plt.ylabel('y - axis')
  
  # giving a title to my graph
  plt.title('My first graph!')
  
  # function to show the plot
  plt.show()
  </code></pre>
