IPython无法绘制3D散点图

Question

当我尝试绘制3D散点图per the instructions here时，得到以下错误：

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:
    %config Application.verbose_crash=True

之前，我在使用PyQt4时遇到了这个错误。我花了几个小时安装PyQt5 (在我的Ubuntu版本上很困难)。现在使用以下命令启动ipython

ipython --pylab='qt5'

我希望它能正常工作，但在尝试绘图时再次得到相同的错误信息。

请注意，当我调用scatter方法时会发生这种情况。然后，在我关闭该图之前，每当我在ipython中点击enter时，它都会继续给出相同的回溯。

你知道我可能做错了什么吗？

看来我找到问题了。不带**的I was passing some keyword arguments到scatter()。

啊。
