Python的Tkinter库的安装

在FCN代码中运行infer.py时出现如下错误：

File "infer.py", line 4, in <module>
import matplotlib.pyplot as plt
File "/usr/local/lib/python2.7/dist-packages/matplotlib/pyplot.py", line 115, in <module>

return _import_module(self.mod)
File "/usr/local/lib/python2.7/dist-packages/six.py", line 82, in _import_module
__import__(name)
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 42, in <module>
raise ImportError, str(msg) + ‘, please install the python-tk package‘
ImportError: No module named _tkinter, please install the python-tk package

解决办法：

Tkinter是Python的GUI widget。一般情况下Linux都没有自带，要自己安装。

1、确定Tkinter没有安装：
>>> import Tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 41, in ?
    raise ImportError, str(msg) + ‘, please install the python-tk package‘
ImportError: No module named _tkinter, please install the python-tk package
>>>

2、安装Tkinter：
$sudo apt-get install python-tk

3、安装成功：
>>> import Tkinter
>>>
