我的基于QT 5.8的代码无法在某些Windows机器上运行任何OpenGl命令。好像它找不到合适的渲染API 这是终端日志的相对部分。

看这行：
qt.qpa.gl：GPU功能：QSet（“ disable_desktopgl”）
qt.qpa.gl：禁用桌面GL：GpuDescription（vendorId = 0x8086， deviceId = 0x102，subSysId = 0x2abf103c，revision = 9，驱动程序： “ igdumd64.dll”，版本= 9.17.10.4459，“ Intel（R）HD Graphics”）
它表示此图形卡上禁止使用台式机OpenGL，因此创建了Angle上下文。但是您的OpenGL代码不是GLES 2.0代码，因此无法正常工作。 您可以通过设置以下属性来覆盖图形检查：
result = np.sqrt(
m ** 2
+ ((reshaped_x - x) / m) ** 2
+ 2 * reshaped_x ** 2
+ 2 * x ** 2
) / 2
应在创建QApplication之前进行设置。 https://www.qt.io/blog/2014/11/27/qt-weekly-21-dynamic-opengl-implementation-loading-in-qt-5-4
