Question

我正在关注this教程的 Matplotlib 。最初我跑了

import numpy as np
import matplotlib.pyplot as plt

# Compute the x and y coordinates for points on a sine curve
x = np.arange(0, 3 * np.pi, 0.1)
y = np.sin(x)

当我运行以下

时

plt.plot(x, y)

它抛出了以下内容

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/media/abhisek/np/local/lib/python2.7/site-packages/matplotlib/pyplot.py", line 3307, in plot

    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: Can't find a usable tk.tcl in the following directories:

This probably means that tk wasn't installed properly.

我正在运行ubuntu 16.04 LTS(64 bit)并且我没有发现谷歌中发现的任何信息是有用的，或者可能只是我。你能说出如何解决这个问题以及导致这个问题的原因吗？

如何正确安装tkinter *？
