Hello,
I just installed "Anaconda3 for Windows v2.4.0" on my Windows 10 Home (64
bit) machine.
(Downloaded the Windows 64-bit Graphical Installer
"Anaconda3-2.4.0-Windows-x86_64.exe" (392 MB) from
https://www.continuum.io/downloads)
In a Command Prompt window, I did the conda "Test Drive", including "conda
update conda", etc, and in the end see the following:
C:\Users\Anshul\Downloads\Python>conda update conda
Fetching package metadata: ....
# All requested packages already installed.
# packages in environment at C:\Anaconda3:
#
conda 3.18.6 py35_0 defaults
C:\Users\Anshul\Downloads\Python>conda list matplotlib
# packages in environment at C:\Anaconda3:
#
matplotlib 1.5.0 np110py35_0 defaults
The installation seems to have been successful:
C:\Users\Anshul\Downloads\Python>python
Python 3.5.0 |Anaconda 2.4.0 (64-bit)| (default, Nov 7 2015, 13:15:24) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Hello World
>>> import os

However, I get an error message when I try to import "matplotlib.pyplot"
as below (note that matplotlib appears to be imported fine):
>>> import matplotlib.pyplot as pp

I opened "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py" in a
text editor and tried to look for the source of the error. I think this is
where things are going wrong:
>>> mpl.get_cachedir()
'C:\\Users\\Anshul\\.matplotlib'
>>> mpl.get_configdir()
'C:\\Users\\Anshul\\.matplotlib'
>>>
But I'm at a loss as to why this is happening, and how to rectify it.
Please help.
Thanks,
