title: Why cf.go_offline doesn't work in pyCharm
body: <p>I am trying to create plots using cufflinks in pycharm. I am going offline as suggested in the previous posts, but I don't have any influence and it seem like the program is skipping the command.</p>
  
  <p>I tried to downgrade plotly but it didn't work and higher version of plotly (4) is not compatible with cufflinks.</p>
  
  <pre><code>import cufflinks as cf
  import pandas as pd
  import numpy as np
  from plotly import __version__
  from plotly.offline import *
  from matplotlib import pyplot as plt
  init_notebook_mode(connected=True)
  cf.go_offline()
  
  
  df=pd.DataFrame(np.random.rand(100,4),columns='A B C D'.split())
  df.iplot()
  plt.show()
  
  # The error I am getting is:
  
  Aw, snap! We didn't get a username with your request.
