No module named 'mujoco_py.mjlib' #80
Comments
|
Updating the gym mujoco environments is on the roadmap, but for now gym's mujoco environments use the 0.5 version of mujoco-py. (gym itself doesn't require mujoco-py, though) https://github.com/openai/gym/blob/master/setup.py#L14 calls out the specific version needs. It's recommended to use python environments to have separate versions of mujoco-py for different uses. |

I'm using the mujoco envs in gym which do use the mujoco-py bindings, and
I'd like to switch to the latest version so I can make use of the headless
rendering on a remote server. Any idea if that's an easy change I can make
myself?

I think so. The mujoco environment wrappers (in gym) would need to be updated, as internal state (e.g. the XML files can stay the same I think. |
|
So I replaced mjlib and model.data with the new versions pymjmodel and
mjsim (I think) but am again getting glfw errors:
File
"/opt/conda/envs/pytorch-py35/lib/python3.5/site-packages/mujoco_py-1.50.1.10-py3.5.egg/mujoco_py/mjviewer.py",
line 132, in __init__
super().__init__(sim)

super().__init__(sim)
File "mujoco_py/mjrendercontext.pyx", line 246, in
mujoco_py.cymj.MjRenderContextWindow.__init__

File "mujoco_py/opengl_context.pyx", line 64, in
mujoco_py.cymj.GlfwContext._init_glfw
mujoco_py.cymj.GlfwError: Failed to initialize GLFW
so I assume in the new mujoco_py model and sim got explicitly separated to
enable headless rendering, but I am not familiar enough with the code to
understand how I should change the gym code to support this...and I
probably just re-mucked it up. Any tips? I'm just going through
the mujoco/mujoco_env.py file and fixing all the parts that broke with new
mujoco_py...

We got this working, we'll try to push a PR soon if anyone's interested. |
|
@adamlerer great news, any update about the status of the PR? |
|
Any update? This would be very helpful to me |
|
I extracted the relevant changes into this branch (co-authored with @yayitsamyzhang ): https://github.com/adamlerer/gym/tree/mujoco-1.0 I don't have any test cases except an internal environment that we are working on, so I don't know if it will be accepted as a PR yet, but you can fork that branch and try it out. Let me know if it works for you! |
|
@adamlerer @yayitsamyzhang That's great news. I tried the mujoco-1.0 branch, but got the follow error: Any tips? |
|
Any progress on this? |
|
@jalexvig progress on what? @DoraXingyu I didn't update the individual envs; I think that |
|
@adamlerer Wondering if anyone had been testing this/ working on getting the PR merged |
|
@adamlerer Sorry, not sure what you meant by got this working. |
|
@adamlerer Hi, I tried your gym version, but am getting the error. If possible could you suggest any directions. |
|
Did you install mujoco_py?

@abhigenie92 Not sure if you figured it out already, but just in case: |

@yayitsamyzhang @adamlerer Tried your version of gym, still facing |
|
where do I download the old version of mujoco-py so that the gym will support it? |
|
I am using MacOS Sierra 10.12.6 and Python 3.5.2 Anaconda environment I had an identical issue like @abhigenie92 and previously like #74 I solved it by:
You should be able to have this example working: |
|
@nemanja-rakicevic this worked great! python setup.py install was the main fix |
|
@nemanja-rakicevic thanks for the info. I tried it but for me it failed upon running the example: |
|
@kirk86 so one issue might be that you're using python 3.6, I think gym has problems with 3.6. Another issue could be related to the gcc update. |
|
@nemanja-rakicevic thanks a lot. Appreciate it! I thought that by reading the docs they mentioned that they released PR in which they support python 3.6?
I don't understand why that could be an issue. It's version 5.4.x ? The main error is here: Anyways thanks again. 😉 |
|
@kirk86 : Looks like libglew-dev is not installed. Use all the dependencies mentioned in this Dockerfile: https://github.com/openai/mujoco-py/blob/master/Dockerfile |
|
Has the mjlib module been deleted in mujoco-py? What if I want to use some built-in functions such as mj_fwdPosition? |
Check this example. Basically you can use |

Looks like gym is not compatible with the latest mujoco-py version. When will it be updated/what do I use to replace the mjlib dependency?
