OffscreenRenderer failed. about pyrender HOT 11 CLOSED

@barvin04 I can confirm problem still exist during OffScreen rendering.

the error are:

pyrender/platforms/osmesa.py", line 42, in make_current
    assert(OSMesaMakeCurrent(
AssertionError

from pyrender.

Still having this issue with version 0.1.32

     42         assert(OSMesaMakeCurrent(
     43             self._context, self._buffer, gl.GL_UNSIGNED_BYTE,
---> 44             self.viewport_width, self.viewport_height
     45         ))
     46 

AssertionError: 

Interestingly enough this only happens when I try to run the script in Jupyter. If called from the command line - everything works as expected.

@mmatl
The "Assertion Error" is still there with PyOpenGL(3.1.5) and Pyrender(0.1.45) during OffScreen rendering

from pyrender.

Even got it when set egl as backend

@mmatl , sorry for asking that stupid question and thanks for sharing this wonderful code, now I have successfully made it work!

Just for your information, after I installed pyrender via pip, it seems like there is no 'shaders' folder under in the installation, which trigered a 'No such file' error in running time. So I just downloaded the shaders folder from github repo and copied it to the desired place, and now it is working.

@ChenXuelinCXL There are no stupid questions! I probably just forgot to include the 'shaders' folder in the pip repo. Will double-check that ASAP and fix it. Thanks for the heads up!

Should be fixed with 9a11d4c

from pyrender.

And it's fixed in version 0.1.6, now on PyPi. Thanks @ChenXuelinCXL for the solution.

I am experiencing the same problem. Version 0.1.39.

from pyrender.

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.

from pyrender.

In my case, simply running

apt-get upgrade

solve the problem. Maybe it is related to the gcc version?
