我已经阅读了这些并尝试了解决方案,但仍然无法显示任何内容:
matplotlib show nothing although i called show
Why doesn't pyplot.show() work? [duplicate]
matplotlib does not show my drawings although I call pyplot.show()
我在Ubuntu 12.04上使用Python 2.7.6 | Anaconda 1.9.0(64位)。 我该如何诊断问题并尝试解决?
编辑:
- 首先我编辑了matplotlibrc并将后端更改为GtkAgg(设置为QtAgg)。
- 然后我尝试通过代码更改后端:matplotlib.rcParams [' backend'] =" GtkAgg"
EDIT2 - 从Spyder控制台添加细节(最后没有显示情节):
Python 2.7.6 |Anaconda 1.9.0 (64-bit)| (default, Jan 17 2014, 10:13:17)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
Imported NumPy 1.8.0, SciPy 0.13.3, Matplotlib 1.3.1
Type "scientific" for more details.
>>> scientific
This is a standard Python interpreter with preloaded tools for scientific
computing and visualization. It tries to import the following modules:
>>> import numpy as np # NumPy (multidimensional arrays, linear algebra, ...)
>>> import scipy as sp # SciPy (signal and image processing library)
>>> import matplotlib as mpl # Matplotlib (2D/3D plotting library)
>>> import matplotlib.pyplot as plt # Matplotlib's pyplot: MATLAB-like syntax
>>> from pylab import * # Matplotlib's pylab interface
>>> ion() # Turned on Matplotlib's interactive mode
Within Spyder, this interpreter also provides:
* special commands (e.g. %ls, %pwd, %clear)
* system commands, i.e. all commands starting with '!' are subprocessed
(e.g. !dir on Windows or !ls on Linux, and so on)
>>> plot(range(3))
[<matplotlib.lines.Line2D object at 0x3f3cd50>]
>>> show()

为了使matplotlib
后端选择起作用,您需要安装该后端的Python绑定。例如,您可能正在运行基于GTK的Windows管理器,例如GNOME,但仍然没有Python绑定。根据{{3}},正确的Ubuntu包是python-gtk
。因此,打开您最喜欢的终端模拟器并输入
sudo apt-get install python-gtk
(您需要管理员权限才能执行此操作)。重启你的python / matplotlib会话,你应该好好去。

我最终在Spyder中做到这一点: 偏好 - &gt;控制台 - &gt;外部模块 - &gt;检查为Qt安装Spyder的输入挂钩
答案 2 :(得分:0)
我在小牛队,通过在matplotlibrc中将后端更改为Qt4Agg来解决问题。 (按照另一个答案的说明:Why doesn't pyplot.show() work?)
