Headless rendering EGL (without GLX) about pyrender HOT 31 CLOSED

My problem was gone by this.

from pyrender.

@mmatl I ran your EGL example, but get this error:

Traceback (most recent call last):

Do you know how to solve this problem?

@bhack Great link, thanks so much! Pyglet already had an EGL backend (I had a sample platform for it here), but it hasn't worked very stably as of yet. I'll be keeping an eye on this thread, and I'll add in support for hardware-accelerated headless rendering with EGL as soon as Pyglet supports it cleanly.

Best,
Matt

Hi @bhack,

Thanks for the suggestion. After messing around a lot, I realized that I just had an NVIDIA driver issue with EGL on Ubuntu 16.04. I tried my EGL platform on Google CoLab and it works on newer Ubuntu versions (or if you install your drivers from a runfile). Check it out here. Does that work for you?

from pyrender.

Oops so sorry, forgot to share the link! You should be able to access it now.

Here's the code:

# Render offscreen -- make sure to set the PyOpenGL platform
import os
os.environ["PYOPENGL_PLATFORM"] = "egl"
import numpy as np
import trimesh
import pyrender

# Load the FUZE bottle trimesh and put it in a scene
fuze_trimesh = trimesh.load('pyrender/examples/models/fuze.obj')
mesh = pyrender.Mesh.from_trimesh(fuze_trimesh)
scene = pyrender.Scene()
scene.add(mesh)

# Set up the camera -- z-axis away from the scene, x-axis right, y-axis up
camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0)
s = np.sqrt(2)/2
camera_pose = np.array([
       [0.0, -s,   s,   0.3],
       [1.0,  0.0, 0.0, 0.0],
       [0.0,  s,   s,   0.35],
       [0.0,  0.0, 0.0, 1.0],
    ])
scene.add(camera, pose=camera_pose)

# Set up the light -- a single spot light in the same spot as the camera
light = pyrender.SpotLight(color=np.ones(3), intensity=3.0,
                               innerConeAngle=np.pi/16.0)
scene.add(light, pose=camera_pose)

# Render the scene
r = pyrender.OffscreenRenderer(640, 480)
color, depth = r.render(scene)

# Show the images
import matplotlib.pyplot as plt
plt.figure()
plt.subplot(1,2,1)
plt.axis('off')
plt.imshow(color)
plt.subplot(1,2,2)
plt.axis('off')
plt.imshow(depth, cmap=plt.cm.gray_r)
plt.show()

Have you read about https://stackoverflow.com/questions/34439832/how-to-create-an-opengl-3-3-or-4-x-context-through-egl?

from pyrender.

Cause:

OpenGL 3.3 and above, the corresponding GLSL version matches the OpenGL version

But here i see 3.2:
https://github.com/mmatl/pyrender/blob/master/pyrender/platforms.py#L120

And shaders
#version 330 core

from pyrender.

This require email notification. Can you share in the repo or on gist?
I have a machine to test it.

from pyrender.

Yes it is working correctly.
Of course I need to use savefig in a headless context.

from pyrender.

from pyrender.

I've tested on Ubuntu 16.04

from pyrender.

If you are interested for the readme:
EGL 1.5 on r600, radeonsi, nv50, nvc0 from https://www.mesa3d.org/relnotes/11.0.0.html
So we are talking about 2015 release.
I don't know the updated Intel status.

from pyrender.

Thanks so much! I'll close the issue for now.

I am trying to use pyrender inside a docker image. I get the following error when I try to just import. If I try to import for the second time it goes through and then fails when creating offscreenrenderer. Any suggestions?

@arsalan-mousavian - I am having the same issue. Did you resolve it somehow, or open a new issue? (I am aware this one is closed).

I have seen this post:
https://github.com/NVIDIA/libglvnd/issues/174
but the solution given did not work for me.

from pyrender.

I ended up creating my docker image based of https://hub.docker.com/r/nvidia/cudagl and fixed the issue.

from pyrender.

Thanks for the speedy reply, especially given that the last comment was over two months ago!

Mine is also based on cudagl (have tried 10.0-devel and 10.0-base, to be specific). Could I ask which image you used? And, if possible (I realise time has passed) what apt install packages you used in the run file, in case this is ultimately some sort of missing library issue.

from pyrender.

For the benefit of anyone who reads this at a later date (relevant) - I gave up and switched to a different python package. I couldn't get any of the listed docker images to work for me.

from pyrender.

Haha I have no idea if it works with pyrender, but I use LLVMpipe software rasterization and XVFB to do simple renders in containers to avoid the pain of CUDA/EGL/etc. I just pushed a minimal example which should render a sphere inside a container.

from pyrender.

I have the same problem as @wangg12 :<

thak you very much ， solve my problem

For anyone who might run into this issue and find this issue from Googling: make sure you have libegl1 (or libegl-dev) packages installed.

I get the same error on ubuntu 18, cuda 10, pyrender 0.1.36 with pyopengl 1.30, any helps?

same issue

from pyrender.

Hello guys I met a similar issue with 'OpenGL.error.GLError: GLError( err = 12289', I was doing the offscreen rendering based on Pyrender. Now I solved this problem by calling render.delete(), so every time it will rebuild the rendering again and this issue disappeared. Hope it helps.

where I add this code? could you please give us a example?

from pyrender.

Hi @lingtengqiu , I used the Pyrender example code from here https://pyrender.readthedocs.io/en/latest/examples/quickstart.html , and I added the render.delete() in the end of the script.

import numpy as np
import trimesh
import pyrender
import matplotlib.pyplot as plt
fuze_trimesh = trimesh.load('examples/models/fuze.obj')
mesh = pyrender.Mesh.from_trimesh(fuze_trimesh)
scene = pyrender.Scene()
scene.add(mesh)
camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0, aspectRatio=1.0)
s = np.sqrt(2)/2
camera_pose = np.array([
... [0.0, -s, s, 0.3],
... [1.0, 0.0, 0.0, 0.0],
... [0.0, s, s, 0.35],
... [0.0, 0.0, 0.0, 1.0],
... ])
scene.add(camera, pose=camera_pose)
light = pyrender.SpotLight(color=np.ones(3), intensity=3.0,
... innerConeAngle=np.pi/16.0,
... outerConeAngle=np.pi/6.0)
scene.add(light, pose=camera_pose)
r = pyrender.OffscreenRenderer(400, 400)
color, depth = r.render(scene)
r.delete()

Hope it helps
