[HiroIshida]

I tried to save image by the following way, but I this causes segmentation fault at glGetIntegerv inside
BufferManager.__init__.

Do you have any idea to save image?

import skrobot
import time
import numpy as np

robot = skrobot.models.PR2()
viewer = skrobot.viewers.TrimeshSceneViewer(resolution=(640, 480))
viewer.add(robot)
viewer.show()
time.sleep(3.0)

png_byte = viewer.save_image("hoge.png")

The output is

/usr/lib/python3/dist-packages/requests/__init__.py:89: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (3.0.4) doesn't match a supported version!
  warnings.warn("urllib3 ({}) or chardet ({}) doesn't match a supported "
/home/h-ishida/.local/lib/python3.8/site-packages/skrobot/model/robot_model.py:1691: UserWarning: texture specified in URDF is not supported
  warnings.warn(

for your information the output of pip3 freeze is
freeze.txt
