Offscreen render does not work (GLEW initalization error: Missing GL version) #408

caprest · 2019-05-23T09:01:57Z

Describe the bug
Rendering with off screen fails to initialize.

To Reproduce

import mujoco_py
model = """
<mujoco model="cartpole">
  <worldbody>
    <geom name="floor" pos="0 0 -3.0" size="40 40 40" type="plane"/>
  </worldbody>
</mujoco>
"""


model = mujoco_py.load_model_from_xml(model)
sim = mujoco_py.MjSim(model)
mujoco_py.MjRenderContextOffscreen(sim, device_id=0)

Error Messages
ERROR: GLEW initalization error: Missing GL version

It seems like the error occurs at the first line of this function (mjr_makeContext(self._model_ptr, &self._con, mjFONTSCALE_150))

mujoco-py/mujoco_py/mjrendercontext.pyx

Lines 83 to 93 in 1aeb02e

    
           def _set_mujoco_buffers(self): 
        
               mjr_makeContext(self._model_ptr, &self._con, mjFONTSCALE_150) 
        
               if self.offscreen: 
        
                   mjr_setBuffer(mjFB_OFFSCREEN, &self._con); 
        
                   if self._con.currentBuffer != mjFB_OFFSCREEN: 
        
                       raise RuntimeError('Offscreen rendering not supported') 
        
               else: 
        
                   mjr_setBuffer(mjFB_WINDOW, &self._con); 
        
                   if self._con.currentBuffer != mjFB_WINDOW: 
        
                       raise RuntimeError('Window rendering not supported') 
        
               self.con = WrapMjrContext(&self._con)

(found by print debug)

Furthermore when I add "None" argument at mysterious position
mujoco_py.MjRenderContextOffscreen(sim, None,device_id=0)
images are correctly rendered, though black winodow appears.

Desktop (please complete the following information):

OS: [Ubuntu18.04 ]

I am having the same problem.

gitanshu · 2019-06-04T21:39:35Z

Have you already looked at #268 ?

caprest · 2019-06-05T06:20:26Z

At least, I already tried the solution for LD_PRELOAD and seems like to have correct output

>>> echo LD_PRELOAD
/usr/lib/x86_64-linux-gnu/libGLEW.so

It seems like if you have it render in 'window' mode for the first time, there will be no error. But the following offscreen render will be all zeros (black) matrix. (So, I still didn't fix it.)

ZiwenZhuang · 2019-07-07T03:04:30Z

After gained some insight from my several tests, I found that letting the system render on screen or make a 'window' mode render context will get rid of the problem. But that would lead to a serious buffer problem and get only all zero numpy arrays if you keep using that context viewer, which might due to some OpenGL buffer problems.
Also, I've noticed that PyOpenGL supports OpenGL only from v1.1 to 4.4 (referring to here). But you reported your OpenGL version is 4.6 :)

Solution

Theoretically, you can downgrade your OpenGL version via reinstall a lower version of Nvidia driver. But that would lead to a series of re-installation of Cuda, or more. So I didn't try that.
Let the entire program initialize an on-screen render context ('window' mode) and abandon it. Then, make your off-screen render context as normal, which will ensure you get the image you expected. Although this will leave a black window on your screen and system keep reporting 'mujoco-py not responding'.

I face exactly the same issue.
Any other idea on how to solve that? Thanks

This solved my issue in Ubuntu 18.04.3 LTS:
sudo mkdir -p /usr/lib/nvidia-000
Then add this in ~/.bashrc file:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-000

Issue's been solved!!

See #408 (comment)

I was having the same problem.

I tried below yet, none of them had worked.

Spec

OS: Ubuntu 18.04.3 LTS
GPU: GeForce RTX 2080 with Max-Q Design
Driver: 430
mujoco-py==2.0.2.7

import gym
from gym.wrappers import Monitor

env = gym.make('HalfCheetah-v2')
env = Monitor(env, './video', force=True)
env.reset()
while True:
    obs, r, done, info = env.step([0, 0, 0, 0, 0, 0])
    if done: break

RajK853 · 2019-12-17T19:26:00Z

Recently while installing mujoco-py in a new conda environment to use tensorflow-gpu 1.13.1, I faced the same problem again. My problem was resolved by installing tensorflow-gpu and glew using conda instead of pip. This will also install the supported cuda version in the conda and it might have solved my issue.

Rowing0914 · 2019-12-17T23:32:29Z

This solved my issue in Ubuntu 18.04.3 LTS:
sudo mkdir -p /use/lib/nvidia-000
Then add this in ~/.bashrc file:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-000

@RajK853
Thank you for your sharing! In my case, which is described above, your advice worked well and solved my issue.

So, after I created the empty dir named nvidia-OOO(OOO == 430 in my case), at the first execution of import mujoco_py it started compiling the library again though, everything seems to settle now!

Edit: I am running scripts on PyCharm, which requires some tricky bit in terms of environment variables....

@wangcongrobot did you find the solution?

wangcongrobot · 2020-09-02T22:05:14Z

@seyeeet I use Unity3d to render.

hermanjakobsen · 2020-10-09T07:51:51Z

Has anyone been able to come up with a solution to this problem?

Vigilans · 2020-11-30T09:44:28Z

To sum up: do not link the libraries provided by system packages (e.g., libglew-dev and libegl1-mesa)

/usr/lib/x86_64-linux-gnu/libGLEW.so
/usr/lib/x86_64-linux-gnu/mesa-egl/libEGL.so.1

Instead, link the libraries provided by mujoco and nvidia:

$HOME/.mujoco/mujoco200/bin/libglewegl.so
/usr/lib/nvidia-xxx/libEGL.so.1

A proper environment setup may look like this:

export LD_LIBRARY_PATH=/usr/lib/nvidia-<xxx>:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$HOME/.mujoco/mujoco200/bin:$LD_LIBRARY_PATH
export LD_PRELOAD=/usr/lib/nvidia-410/libEGL.so.1:$LD_PRELOAD
export LD_PRELOAD=$HOME/.mujoco/mujoco200/bin/libglewegl.so:$LD_PRELOAD

Explanation

Inside cymj.OffscreenOpenGLContext, initOpenGL function (EGL version) will be called, which first initializes EGL, then intializes glew by calling glewInit():

mujoco-py/mujoco_py/gl/eglshim.c

Lines 113 to 119 in 4830435

    
           GLenum err = glewInit(); 
        
           if( GLEW_OK != err ) { 
        
               // MuJoCo does this automatically, but we need it if we want 
        
               // to create e.g. PBOs before calling MuJoCo rendering functions. 
        
               fprintf("glewInit error: %s\n", glewGetErrorString(err)); 
        
               return -9; 
        
           }

If the glew library provided by system (libglew-dev) is linked, the glewInit() call will be directed to an implementation which invokes glGetString(GL_VERSION) (sourced from apt source libglew-dev 1.13.0):

  /* query opengl version */
  s = glGetString(GL_VERSION);
  dot = _glewStrCLen(s, '.');
  if (dot == 0)
    return GLEW_ERROR_NO_GL_VERSION;

Which results in the error in the issue. It seems that the EGL is correctly initialized, but the system glew library cannot correctly detect it.

However, mujoco's libglewegl.so seems to provide an implementation of glew with special support for EGL. Linking with this library will let glewInit() correctly execute without error.

Also, libEGL.so.1 should be linked with the nvidia provided one, linking with the libegl1-mesa one will result in segment fault from my tested machine.

Above code comes from cymj, a cython package which will be compiled locally after installing mujoco-py. You make check the library dependency of the generated .so file in this way:

$ python
>>> import mujoco_py
>>> mujoco_py.__file__
'<some-path>/site-packages/mujoco_py/__init__.py'

$ ldd <some-path>/site-packages/mujoco_py/generated/cymj_2.0.2.<xxxxxxxx>.so

A working machine reports the dependency like this:

        linux-vdso.so.1 =>  (0x00007fffb65f8000)
        libglewegl.so => /home/<user>/.mujoco/mujoco200/bin/libglewegl.so (0x00007f1a0a1c1000)
        libmujoco200.so => /home/<user>/.mujoco/mujoco200/bin/libmujoco200.so (0x00007f1a09e0e000)
        libEGL.so.1 => /usr/lib/nvidia-418/libEGL.so.1 (0x00007f1a09c08000)
        libOpenGL.so.0 => /usr/lib/nvidia-418/libOpenGL.so.0 (0x00007f1a099d3000)
        libgomp.so.1 => /usr/lib/x86_64-linux-gnu/libgomp.so.1 (0x00007f1a097b1000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f1a09594000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f1a091ca000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f1a08e48000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f1a08b3f000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f1a08929000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f1a08725000)
        libGLdispatch.so.0 => /usr/lib/nvidia-418/libGLdispatch.so.0 (0x00007f1a08452000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f1a0a69a000)

A non-working machine will typically include dependencies like:

/usr/lib/x86_64-linux-gnu/libGLEW.so (0x00007fa44cf82000)

And once you added libGLEW.so to the LD_PRELOAD, the glewInit() may be forwarded to the implementation of it and the error happens thereafter.

@seyeeet did you find the solution?

When I reinstall my OS system from Ubuntu16.04 to Ubuntu18.04, the solution above works fine.

hermanjakobsen · 2021-01-18T10:03:41Z

Hi @Vigilans!

Thank you for coming up with what seems to be a viable solution. 😄 However, I am not very proficient at modifying linked packages etc on Ubuntu and I am therefore terrified of messing something up. I would therefore be thrilled if you could make a step-by-step guide for us dummies 😅

What I have previously tried is to create an empty folder

sudo mkdir -p /usr/lib/nvidia-455

and added the following to ~/.bashrc

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-455

When I then ran

This solved my issue in Ubuntu 18.04.3 LTS:
sudo mkdir -p /use/lib/nvidia-000
Then add this in ~/.bashrc file:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-000

@RajK853 Thank you for your sharing! In my case, which is described above, your advice worked well and solved my issue.

So, after I created the empty dir named nvidia-OOO(OOO == 430 in my case), at the first execution of import mujoco_py it started compiling the library again though, everything seems to settle now!

Edit: I am running scripts on PyCharm, which requires some tricky bit in terms of environment variables....

and how to know the 000?

Maybe it's the nvidia driver version installed in your Ubuntu.

这解决了我在 Ubuntu 18.04.3 LTS 中的问题：
sudo mkdir -p /use/lib/nvidia-000
然后将其添加到 ~/.bashrc 文件中：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-000

@RajK853感谢您的分享！就我而言，如上所述，您的建议效果很好并解决了我的问题。
因此，在我创建了名为nvidia-OOO（OOO == 430在我的例子中）的空目录之后，在它第一次执行时import mujoco_py再次开始编译库，现在一切似乎都解决了！
编辑：我在 PyCharm 上运行脚本，这需要一些棘手的environment variables......

以及如何知道000？

也许这是您的 Ubuntu 中安装的 nvidia 驱动程序版本。

Sad, it does not work for me.

Sad to hear that. I am not sure if this will help but recently I reinstalled the packages again in my conda environment and I was able to solve the issue with the mujoco with these settings. Hope it helps
