def main():
    x = np.arange(0, 5, 0.1)
    y = np.sin(x)
    plt.plot(x, y)

if __name__ == '__main__':
    main()

As mentioned by @Grzegorz Bokota, the problem is coming from the "scientific view mode" of PyCharm. This mode allows to visualise graphs and is thus calling matplotlib, and probably an incompatible version of it if you are using Python 2. This bug has been identified here and it seems that we just have to wait for the next release to get it solved.

Simple answer: disable "show plots in scientific window" (Settings -> Tools -> Python Scientific) or downgrade the PyCharm or move your project to python3
Remember to add plt.show() in your code.

A little more complicated. You need to write own importing hooks to find that urllib.parse and urllib.request (next line in display_.py file are requested. More you can read here https://xion.org.pl/2012/05/06/hacking-python-imports/

(i'm not enough familiar with python 2 import system to write it)

For python 2 use

from urlparse import urlparse

If you need to write code which is Python2 and Python3 compatible you can use the following import

try:
    from urllib.parse import urlparse
except ImportError:
     from urlparse import urlparse

In your PyCharm project:

  • press Ctrl+Alt+s to open the settings
  • on the left column, select Project Interpreter
  • on the top right there is a list of python binaries found on your system, pick the right one
  • eventually click the + button to install additional python modules, in your case, it is parse module is missing so install that one
