Error when installing anaconda3 and attempting import matplotlib.pyplot in bash on windows

[Symptoms]
Installing anaconda3 in bash on windows and running the matplotlib demo file dete_demo.py results in an error.

[Procedure]
● lxrun/uninstall, lxrun/install
● bash Anaconda3-4.2.0-Linux-x86_64.sh
● python-V# Python 3.5.2::Anaconda 4.2.0 (64-bit)
● python date_demo.py## Appended error 1

行ったResponse 対応
Do I have to install PyQt4 because it says No module named 'PyQt4'?
● conda list | greppyqt##pyqt5.6.0py35_0
● conda list | grep PyQt4## None
● conda search PyQt4##None
● pipsearchPyQt4##PyQt4(4.11.4) was in the list
● pip install PyQt4##Attachment error 2
● pip install --upgrade pip
● pip install PyQt4## Appended Error 3

I've done it three times, but it was the same symptom

Please let me know if you have any tips or advice.

WindowsAnaconda3 for Windows displays the graph correctly.

[Additional note, what I did after that]
stackoverflow.com had a page for the same symptom.
Is pyqt5 the cause...?
We have taken the last step.

conda install-ypyqt=4.11

Now there are no more errors for PyQt4, but

A new libSM.so.6 error occurred.
There was a page on stackoverflow.com for the same symptom, so we took action.

 apt-get install libsm6 libxrender1 libfontconfig1

Now the above error is gone, but

RuntimeError: Invalid DISPLAY variable appears.orz

As the display cannot be displayed, we decided to save the graph as an image as a short-term response.
※ date_demo.py See correction code

However, the image is not saved. (Tears) orz *The image will be saved with the same code in the Windows version.

So far...

As of November 26, 2016, I received the following report.

Now that I've solved it myself, I'd like to write it down for those with the same symptoms.

●anaconda3 Installation
● conda install nomkl
● sudo apt-get install x11-apps
● Install xming and launch Xming.exe in Windows 10

Test Code

import matplotlib as mpl
mpl.use('tkagg')
import matplotlib.pyplot asplt
import numpy as np

x = np.range (-3,3,0.1)
y = np.sin(x)
plt.plot(x,y)
plt.savefig('test.png')
plt.show()

The PyQt4 error has not been resolved, but matplotlib is now able to save and display images of graphs.
