这是我从功能我会在底部提供得到的错误:Matplotlib错误:乳胶无法处理以下字符串:“LP”

这是我的功能“M使用创建上述错误:

def Derivative(inputArrayList,rowNumber_from_top): 
    for image in inputArrayList: 
     rowValues = image[0][rowNumber_from_top] 
     for i in range(len(rowValues)):   
      # Perform the difference derivative estimation 
      if i == 0 or i == (len(rowValues) - 1): 
       rowValues[ i ] = 0 # set edges to 0 
      else: 
       derivative = (rowValues[ i+1 ] - rowValues[ i-1 ])/(2.0) 
       rowValues[ i ] = derivative 
     plt.rc('text', usetex=True) 
     plt.rc('font', family='serif') 
     plt.plot(rowValues,color="k") 
     plt.ylim((0,image.max() + 10.0)) 
     plt.title(r"$\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi}}{2^n}$") 
     plt.show() 

通知线路plt.title(r"$\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi}}{2^n}$")。我从first graph上Matplotlib的网站采取了这种(和我试着运行该程序,以及他们提供的),我似乎无法得到它的工作。我几乎肯定这是一个简单的修复(就像我可能缺少一个LaTeX模块或其他东西?)。

整个目标是能够使用命令\displaystyle在标题和情节的标签,让分数变大。

我道歉,如果这是一个重复的(虽然我无法找到一个类似的问题),我只需要一个指针,让我朝着正确的方向发展。

谢谢您的时间,

有没有经过“这里是乳胶生成完整的报告:”什么?你也可以看到,如果这是有帮助的:http://stackoverflow.com/questions/11354149/python-unable-to-render-tex-in-matplotlib –

@AmyTeegarden不幸的是,不,“后下面是生成的完整报告乳胶:'它是空白的。感谢您的链接!我会看看type1cm。 – bjd2385

你能直接处理在LaTeX的那条线,通过matplotlib没有运行?如果它不调用'\ displaystyle',你能处理它吗?你可以运行使用LaTeX的Matplotlib图库示例代码吗? – cphlewis

,如果你已经安装了乳胶您应该测试。为此,打开一个终端输入

which latex 

输出应该是你的乳胶二进制文件的路径。如果找不到,请尝试安装乳胶分布。这个过程取决于你的操作系统,例如Ubuntu有几个包。
