Error: failed to send plot to http://127.0.0.1:63342 when trying to plot any NILMTK plot on Pycharm!

Hi! I am trying to plot the raw power data of the fridge from the UK-DALE dataset from building 1 using the following code:

import matplotlib.pyplot as plt
from nilmtk import DataSet, MeterGroup

elec = uk_dale.buildings[1].elec
fridge_meter = elec['fridge']
fridge_meter.plot()
plt.show()

However, I receive the following error on Pycharm

Error: failed to send plot to http://127.0.0.1:63342

I don't really understand this error, and the only solution (which was not a solution in the end) was to disable "Show plots in tool window" in Pycharm Settings, which just printed absolutely nothing (no errors, no plot).

I would appreciate any help. Thanks!
