如何解决 import matplotlib.pyplot as plt 错误？

Question

I am having trouble getting my matplotlib library to work. I am running it on a virual environment, and I have installed numpy, and matplotlib. I first open my virtual environment, activate python, then I enter,

import matplotlib 

everything goes fine, but then I enter,

import matplotlib.pyplot as plt

I get the error,

    Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/kendallreid/.virtualenvs/cv/lib/python2.7/site-packages/matplotlib/pyplot.py", line 115, in <module>

    return _import_module(self.mod)

    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter

I have tried a number of different solutions to no avail. What could be the problem?

Use the below mentioned commands:

import matplotlib
matplotlib.use(‘TkAgg’)
import matplotlib.pyplot as plt

This worked for me. I hope it helps.
