請教各位大神，我在使用pyqtgraph和GLViewWidget畫3D散點圖時遇到了openGL error, 代碼如下：
g = gl.GLGridItem()
self.guiplot.addItem(g)
pos = np.random.random(size=(100000, 3))
pos *= [10, -10, 10]
pos[0] = (0, 0, 0)
color = np.ones((pos.shape[0], 4))
d2 = (pos ** 2).sum(axis=1) ** 0.5
size = np.random.random(size=pos.shape[0]) * 10
sp2 = gl.GLScatterPlotItem(pos=pos, color=(1, 1, 1, 1), size=size)
self.guiplot.addItem(sp2)
屏蔽掉sp2時，可以正常運行并顯示出網格g。但當addItem(sp2)時，就會報如下錯誤：
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

)
During handling of the above exception, another exception occurred:

description = b'\xce\xde\xd0\xa7\xb2\xd9\xd7\xf7',

cArguments = (GL_VERSION,)
)
看起來是addItem(sp2)時，initializeGL出問題了
if hasattr(item, 'initializeGL'):
self.makeCurrent()
try:
item.initializeGL()
except:
self.checkOpenGLVersion('Error while adding item %s to GLViewWidget.' % str(item))
求教各位大神有沒有遇到過類似問題，如何解決？ 謝謝！
