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，出现以下错误：

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 版本上很难）。现在已经开始使用 ipython 了

ipython --pylab='qt5'

我预计它会起作用，但在尝试绘图时再次收到相同的错误消息。

请注意，当我调用 scatter 方法时会发生这种情况。然后，直到我关闭该图，每次我在 ipython 中输入时，它都会继续给出相同的回溯。

关于我可能做错了什么有什么想法吗？

Answer 1

看来我发现了问题。 I was passing some keyword arguments 到 scatter() 没有 **。

啊。
