Offscreen renderer gives GLError (eglMakeCurrent)

[atenpas]

After running offscreen rendering a few times, I get the following error.

[...].py", line 296, in createPointCloudFromView depth = self.renderer.render(self.scene, flags=self.flags) File "[...]/env/lib/python3.7/site-packages/pyrender/offscreen.py", line 86, in render self._platform.make_current() File "[...]/env/lib/python3.7/site-packages/pyrender/platforms/egl.py", line 198, in make_current self._egl_context File "[...]/env/lib/python3.7/site-packages/OpenGL/error.py", line 232, in glCheckError baseOperation = baseOperation, OpenGL.error.GLError: GLError( err = 12289, baseOperation = eglMakeCurrent, cArguments = ( <OpenGL._opaque.EGLDisplay_pointer object at 0x7f5c66d3cf80>, <OpenGL._opaque.EGLSurface_pointer object at 0x7f5bf8a5ae60>, <OpenGL._opaque.EGLSurface_pointer object at 0x7f5bf8a5ae60>, <OpenGL._opaque.EGLContext_pointer object at 0x7f5c62539a70>, ), result = 0 )

I'm using EGL, i.e., PYOPENGL_PLATFORM=egl, Python 3.7.5, nvidia-450 and Ubuntu 16.04.

Same issue here. I'm on Ubuntu 18.04, Python 3.6.12, and nvidia 435.21.

In my case, my problem was creating the offscreen renderer within every loop (i.e., calling render = pyrender.OffscreenRenderer). It works okay 'osmesa' as the pyopengl platform. But, for 'egl', it seems to have a problem with automatically get rid of opengl related things. So I just put renderer.delete() that will call the self.delete() of the OffscreenRenderer inside the loop. Hope it helps.

@SuwoongHeo I don't understand what you saying. I got same rror:

/OpenGL/error.py", line 228, in glCheckError
    raise GLError(
OpenGL.error.GLError: GLError(
    err = 12290,
    baseOperation = eglMakeCurrent,
    cArguments = (
        <OpenGL._opaque.EGLDisplay_pointer object at 0x7ff528e2ccc0>,
        <OpenGL._opaque.EGLSurface_pointer object at 0x7ff528e2c2c0>,
        <OpenGL._opaque.EGLSurface_pointer object at 0x7ff528e2c2c0>,
        <OpenGL._opaque.EGLContext_pointer object at 0x7ff528e52bc0>,
    ),
    result = 0
)

  ),
  result = 0
)

@jinfagang Just add renderer.delete() at the next line of rgb, depth = renderer.render(scene, flags=pyrender.RenderFlags.RGBA) as @SuwoongHeo said, that works for me.

I have the same issue (calling renderer.delete() doesn't help). It crashes the first time I instantiate OffscreenRenderer.
