Matplotlib plt.show() method does not pop out the window

Question

I have some problem with matplotlib's plt.show() method. When I run the following code, the plot is displayed inside IPython console. I am using Anaconda with Python 3.5

import matplotlib.pyplot as plt
import numpy as np
import csv

x = []
y = []

with open(r"F:\my_dir\example.txt", 'r') as csvfile:
    plots = csv.reader(csvfile, delimiter = ',')
    for row in plots:
        x.append(int(row[0]))
        y.append(int(row[1]))

plt.plot(x,y, label = 'Loaded from file')

plt.xlabel("x")
plt.ylabel("y")
plt.title("This is my plot")
plt.legend()

plt.show()

example.txt is as follows.

1,3
2,6
3,1
4,8
5,9
6,2
7,9
8,5
9,4
10,17

I am also pasting the matplotlibrc file content here

The plt.get_backend() command on the console gives

'module://ipykernel.pylab.backend_inline'

I want the script to pop out the plot window. This used to happen earlier but now it has stopped. Please help

I installed Anaconda just over 2 weeks ago. And plt.show() used to get me pop out window till yesterday. Only today this strange behavior has started — user9026

Does it even create the plot? Try to use "savefig" and see if it fails at generating the plot or at showing it. — PhilipB

Philip, It does show the plot inside IPython console. I want to have pop up window for the plot. — user9026

Found answer here. type %matplotlib qt when you want graphs in a separate window and %matplotlib inline when you want an inline plot — user9026

In Spyder, click Tools, Preferences, Ipython Console, Graphics. Under Graphics, change Backend to “automatic” instead of “inline”.

Thanks pyan. This really helps.

But in addition, after following the above step, please restart your kernel to see the effect. Shortcut is "Ctrl+."
