I installed matplotlib using pip. But I couldn't import this when I tried in ipython notebook. I wrote,

import matplotlib.pyplot as plt

and outputs is

--------------------------------------------------------------------------

ValueError: unknown locale: UTF-8

Please tell me the solution for this.

  • Have you tried [this solution](http://stackoverflow.com/questions/19961239/pelican-3-3-pelican-quickstart-error-valueerror-unknown-locale-utf-8)? – j08lue Feb 09 '16 at 08:52
  • When you get an error in Python, look up just the error, like `ValueError: unknown locale: UTF-8`, seasoned with `python` and perhaps the name of the module, and you will find... – j08lue Feb 09 '16 at 08:57
  • I tried that solution and I could import matplotlib. Thanks! – Yuchi Matsuoka Mar 19 '16 at 12:50
