這是我從功能我會在底部提供得到的錯誤：Matplotlib錯誤：乳膠無法處理以下字符串：「LP」
'latex' is not recognized as an internal or external command,
operable program or batch file.

這是我的功能「M使用創建上述錯誤：
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()
通知線路plt.title(r"$\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi}}{2^n}$")。我從first graph上Matplotlib的網站採取了這種（和我試着運行該程序，以及他們提供的），我似乎無法得到它的工作。我幾乎肯定這是一個簡單的修復（就像我可能缺少一個LaTeX模塊或其他東西？）。
整個目標是能夠使用命令\displaystyle在標題和情節的標籤，讓分數變大。
我道歉，如果這是一個重複的（雖然我無法找到一個類似的問題），我只需要一個指針，讓我朝着正確的方向發展。
謝謝您的時間，

有沒有經過「這裏是乳膠生成完整的報告：」什麼？你也可以看到，如果這是有幫助的：http://stackoverflow.com/questions/11354149/python-unable-to-render-tex-in-matplotlib –
@AmyTeegarden不幸的是，不，「後下面是生成的完整報告乳膠：'它是空白的。感謝您的鏈接！我會看看type1cm。 – bjd2385
你能直接處理在LaTeX的那條線，通過matplotlib沒有運行？如果它不調用'\ displaystyle'，你能處理它嗎？你可以運行使用LaTeX的Matplotlib圖庫示例代碼嗎？ – cphlewis
