IPython中無法繪製3D散點圖

Question

當我嘗試繪製一個三維散點圖per the instructions here，我得到以下錯誤：

In [10]: Traceback (most recent call last): 
    File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_qt5agg.py", line 176, in __draw_idle_agg

If you suspect this is an IPython bug, please report it at: 
    https://github.com/ipython/ipython/issues 
or send an email to the mailing list at ipython-dev@scipy.org 

You can print a more detailed traceback right now with "%tb", or use "%debug" 
to interactively debug it. 

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:

以前我使用PyQt4的時候得到這個錯誤。我花了幾個小時安裝PyQt5（在我的Ubuntu版本上很難）。現在開始ipython與

ipython --pylab='qt5' 

我預計它會工作，但再次嘗試繪圖時得到相同的錯誤信息。

請注意，當我調用scatter方法時會發生這種情況。然後，直到我結束這個數字，每次我在ipython中輸入時它都會繼續給出相同的回溯。

任何想法，我可能做錯了什麼？

看來我發現了這個問題。 I was passing some keyword arguments到scatter()而沒有**。

Argh。
