Python installation error no matching distribution found for pyplot

Question

I am trying to run this program

import matplotlib.pyplot as plt
import numpy

plt.plot([1, 2, 3],[5, 7, 4])
plt.show()

I am getting an error message: ImportError: No module named pyplot

I have installed matplotlib on Windows 8 64-bit, Python 2.7 with pip command from bash and I also updated it, got this message as a result:

Aneta@AKZ-5K-Computer:~$ C:/Python27/Scripts/pip install --upgrade matplotlib

Requirement already up-to-date: six>=1.4 in c:\python27\lib\site-packages\six-1.10.0-py2.7.egg (from matplotlib)

When I tried to install pyplot I got this massage:

Aneta@AKZ-5K-Computer:~$ C:/Python27/Scripts/pip install pyplot
Collecting pyplot
  Could not find a version that satisfies the requirement pyplot (from versions: )
No matching distribution found for pyplot

If anyone has an idea how to install pyplot and why my distribution is not matching, I appreciate your help.

Solution 1

Try reinstalling matplotlib from here. It doesn't matter if you're on a 64 bit computer (I am as well). What matters is which version of Python did you install? If you installed the 32-bit (recommended as it's somewhat easier to deal with), then you still install the 32-bit versions of modules.

The site I linked you shows prerequisite modules for matplotlib, so make sure you also have those installed.

Solution 2

Or what you can do is just try pip install matplotlib. Then import matplotlib.pyplot to make get the pyplot data. matplotlib is a module with pyplot inside it so you can access pyplot easily.

Solution 3

If you try

pip install matplotlib

and it fails, try

pip install --upgrade matplotlib

You might already have the package pre-installed.

This is the main point: pip install matplotlib so that you can import matplotlib.pyplot as plt or import pylab
