推荐答案

我怀疑你的显卡没有帧缓冲扩展。



看看从python调用opengl扩展的过程。



[ ^ ]



我没有opengl的经验在python中。在Windows中，我检索了函数指针以获取帧缓冲扩展函数。如果我尝试在没有显卡的PC中运行我的应用程序，它将返回glgenframebuffer函数的NULL指针。

I suspect your graphics card do not have framebuffer extension.

Have look at the procedure to call opengl extensions from python.

[^]

I have no experience in opengl in python. In windows I have retrieve the function pointers to get framebuffer extension functions. If I try to run my application in a pc without Graphics card it will return NULL pointer for glgenframebuffer function.
