Linux 禁用OpenGL for Python/Matplotlib

我正在学习一门Python课程，为此我在虚拟机中安装了ArchLinux。当我使用Matplotlib.pyplot来绘制东西（x对y）时，我会得到一系列错误

当我开始使用虚拟机的3D支持时，它只是要求使用openGL。我的脚本确实创建了一个绘图（空画布），但没有线条

我认为在没有openGL的情况下应该可以画一些线，对吗？如何处理这件事

---

编辑：我认为这是一个VirtualBox错误，加上Python代码中的一个错误。事实上，我可以得到很好的图表，最后显示错误消息。在最新版本的VirtualBox中，我不再出现错误。Thanx感谢您的建议。

因此，尽管有所有的错误，我从来没有发现任何不起作用的东西，事实上，我没有看到图表并不是因为原始帖子中的错误。我想这与mpl无关，更多的是与VirtualBox中缺乏3D加速有关。

mpl没有（直接）接触openpl。您是否也在使用

vispy

？我的猜测是，这更通用，并且与gui工具包所做的事情相关，而不是特定于mpl。而且，您的虚拟机在与视频卡通信时出现硬件问题。我使用import matplotlib.pyplot作为plt，我认为这与Virtualbox不支持opengl 3这一事实有关。但我一直在想，在python中，我应该能够完全不使用硬件加速。它与

Agg

后端（

matplotlib.use（'Agg'）

）一起工作吗？我认为这最终是一个virtualbox bug。我再也看不到这个错误了，而且我在自己的Python代码中发现了一个错误，尽管有这个错误，我还是可以得到很好的输出。
