title: Python IDLE code gives error upon installation of matplotlib
body: <p>Python 3.6.0 (32-bit) is installed on my Windows 10 machine (64-bit).
  This is office machine and Python is installed by IT team.
  I'm using IDLE to run code.
  Without installing matplotlib, the code runs fine.
  However, as soon as matplotlib is installed, even the existing code does not run.</p>
  <pre><code>    Traceback (most recent call last):
        File &quot;C:\Users\saurabh.gupta1\lib\pathlib.py&quot;, line 1231, in mkdir

  <p>It is looking for K: drive which does not exist. Not sure why its doing so!</p>
  <p>Tried reducing the code to a minimal in my .py file.
  It gives above error even with only 1 statement in the .py file e.g.</p>
  <pre><code>    check.py with following line of code:
      import matplotlib
  </code></pre>
  <p>Any help is appreciated. thanks.</p>
