pyrender.OffscreenRenderer fail

[liwenssss]

Hello, I run a test code:

import os
os.environ['PYOPENGL_PLATFORM'] = 'osmesa'
import pyrender

pyrender.OffscreenRenderer(viewport_width=224, viewport_height=224,point_size=1.0)

and got the error:

Traceback (most recent call last):
  File "test.py", line 8, in <module>
    point_size=1.0)
  File "/home/liwensh2/.conda/envs/SPIN/lib/python3.6/site-packages/pyrender/offscreen.py", line 31, in __init__
    self._create()
  File "/home/liwensh2/.conda/envs/SPIN/lib/python3.6/site-packages/pyrender/offscreen.py", line 135, in _create
    self._platform.make_current()

    self.viewport_width, self.viewport_height

can you give me some help?Thanks!

After I build omesa from source , got the same error. Need Help orz..

I keep on getting the same error.

I was able to reproduce it in different Docker containers, by simply installing pyrender and libosmesa6-dev.

Traceback (most recent call last): File "pyrender_example.py", line 30, in <module> r = pyrender.OffscreenRenderer(640, 480) File "/notebooks/voca/pyrender/pyrender/offscreen.py", line 31, in __init__ self._create() File "/notebooks/voca/pyrender/pyrender/offscreen.py", line 135, in _create self._platform.make_current() File "/notebooks/voca/pyrender/pyrender/platforms/osmesa.py", line 44, in make_current self.viewport_width, self.viewport_height AssertionError

Searching on forums suggests that Mesa can't create OpenGL context.

Any help would be appreciated.

In my case, the problem magically disappeared after running:

module load LLVM/6.0.0-GCCcore-7.3.0

It may be related to LLVM somehow.

I am experiencing the same problem in version 0.1.45. Does anyone have solved this problem?
