Python 伊皮顿罐头'；t绘制三维散点图

当我尝试绘制三维散点图时，会出现以下错误：

In [10]: Traceback (most recent call last):

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

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）。从现在开始，伊普顿

ipython --pylab='qt5'

我希望它能工作，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，在我关闭图形之前，每次我在ipython中按enter键时，它都会继续给出相同的回溯

你知道我做错了什么吗？

Argh.

您是否使用了mpl_toolkits.mplot3d导入Axes3D中的

和
ax=fig.add_子图（111，projection='3d'）
？（如果您显示了导致错误的所有命令，这将很有帮助。）您是否使用了mpl_toolkits.mplot3d导入Axes3D和
