Matplotlib pyplot.title(string) returns error
提问by olben1
When I call pyplot.title('some string')it throws the exception, 'str' object is not callable'.
I copied the following from the matplotlib online documentation:
当我调用pyplot.title('some string')它时抛出异常，'str' object is not callable'. 我从 matplotlib 在线文档中复制了以下内容：
mu, sigma = 100, 15
x = mu + sigma * np.random.randn(10000)
# the histogram of the data
n, bins, patches = plt.hist(x, 50, normed=1, facecolor='g', alpha=0.75)
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title('Histogram of IQ')
plt.text(60, .025, r'$\mu=100,\ \sigma=15$')
plt.axis([40, 160, 0, 0.03])
plt.grid(True)
plt.show()
and get
并得到
TypeError Traceback (most recent call last)
<ipython-input-158-40fe7a831b06> in <module>()
8 plt.xlabel('Smarts')
9 plt.ylabel('Probability')
---> 10 plt.title('Histogram of IQ')
11 plt.text(60, .025, r'$\mu=100,\ \sigma=15$')
12 plt.axis([40, 160, 0, 0.03])
TypeError: 'str' object is not callable
pyplot.suptitle()works OK
pyplot.suptitle()工作正常
I'm using python 2.7.5 and the latest release of matplotlib on an iMac with an I7 processor OSX 10.8 and 8 gig ram and ipython notebook.
我在带有 I7 处理器 OSX 10.8 和 8 gig ram 以及 ipython 笔记本的 iMac 上使用 python 2.7.5 和最新版本的 matplotlib。
Does anyone know what's going on?
有谁知道发生了什么？

Had the same problem olben1, using ipython, anaconda and the --pylab flag. Reinstalled and it worked. Fwiw, using an anaconda env makes the uninstall/reinstall easier..

I had the same problem. The code was fine, but in the interpreter, I had previoulsy used incorrect xlabel() calls. re-starting the interpreter (close and reopen it) was enough for me, no need to reinstall all python/matplotlib !
我有同样的问题。代码很好，但是在解释器中，我以前使用了不正确的 xlabel() 调用。重新启动解释器（关闭并重新打开它）对我来说就足够了，无需重新安装所有 python/matplotlib ！

It happened to me because I tried to do plot.title = "Some string"so that rewrote the title()method. That's the exact reason why it happens :) .
As others have said you just need to restart the kernel, no need to reinstall.
它发生在我身上，因为我试图这样plot.title = "Some string"做重写了title()方法。这就是它发生的确切原因:)。正如其他人所说，您只需要重新启动内核，无需重新安装。

I've had this happen when I've previously accidentally plt.title = ''
我以前不小心 plt.title = '' 时发生过这种情况
After that that function is no longer a function. Restarting python kernel or re-importing plt library can fix it.
之后那个函数就不再是函数了。重新启动python内核或重新导入plt库可以解决它。
Not re-installing. Re-IMPORTING.
不是重新安装。重新进口。

Without restarting, I've found that changing to a .set_title()method following my plotting method has resulted in a successful pass without an error.
无需重新启动，我发现更改为.set_title()遵循我的绘图方法的方法已成功通过而没有错误。
