I also separately tried to install by cloning the repo and running python setup.py install. That command runs without errors, but afterwards when I import mujoco_py in python I get the following, similar error:

Could someone help me work through this bug? Thanks for the help!

EDIT: GOMP seems to be a gcc thing, so here's my gcc version if anyone was wondering:

This is my gcc version (I'm using OSX sierra), though I'm not sure it's what's wrong in this case:

Hmm...

$ brew install gcc@6 --without-multilib

doesn't seem to install a gcc without multilib.

$ brew install gcc@6 --without-multilib

Has anyone else got this to work? There are some posts on the interwebs about this not working in homebrew... but looks like @machinaut got it to work?

Thanks all.

P.S. I am also on OSX Sierra, 10.12.6

I did finally get it to work using gcc@5, specifically:

$ brew install cmake boost boost-python sdl2 swig wget
$ pip install 'gym[all]'
$ brew install gcc@5

(Thanks to @JoeNyland in this thread https://github.com/dmlc/xgboost/issues/1501 )

Then put this in your .bash_profile (easy to undo later):

alias gcc='gcc-5'
alias cc='gcc-5'
alias g++='g++-5'
alias c++='c++-5'

Then (after you source .bash_profile) this works:

pip install 'mujoco-py<1.50.2,>=1.50.1'

(Don't forget to undo .bash_profile changes.)

Now unfortunately I have hit the "No module named 'mujoco_py.mjlib'" issue! https://github.com/openai/mujoco-py/issues/80 :-(

All of the above was with Python 3.5.4 and mujoco150. I can't use mujoco131 because I have a new Mac and it fails with "ERROR: Could not open disk" as here: https://github.com/openai/mujoco-py/issues/36 https://github.com/openai/gym/issues/638

It took me awhile, but the above comment helped me get it working for OSX. This is what I did:

openAI/gym install on OSX 10.12.6, with mujoco

# create conda env with python v3.5.2
# https://github.com/openai/mujoco-py/issues/47#issuecomment-312551946
conda create --name gym python=3.5.2
source activate gym
mkdir -p ~/openai && cd ~/openai

# install gym
# https://github.com/openai/mujoco-py/issues/74#issuecomment-338410266
brew install cmake boost boost-python sdl2 swig wget

# see: https://github.com/openai/gym/issues/164#issuecomment-263785233
export MACOSX_DEPLOYMENT_TARGET=10.12
# pip install 'gym[all]'
git clone https://github.com/openai/gym.git
cd ./gym
pip install -e '.[all]'
brew install gcc@5

## use gcc5
# add to ~/.bash_profile
alias gcc='gcc-5'
alias cc='gcc-5'
alias g++='g++-5'
alias c++='c++-5'
# source ~/.bash_profile

## install mujoco v1.50 binaries
cd ~/openai
mkdir ~/.mujoco
# NOTE: remember to copy mujoco license key to ~/.mujoco/mjkey.txt

# download OSX binaries
wget https://www.roboti.us/download/mjpro150_osx.zip
unzip mjpro150_osx.zip && mv mjpro150  ~/.mujoco  

# wget https://www.roboti.us/download/mjpro131_osx.zip
# unzip mjpro131_osx.zip && mv mjpro131  ~/.mujoco 
git clone https://github.com/openai/mujoco-py.git

# pwd: cd ~/openai
rm -rf mujoco-py
git clone https://github.com/openai/mujoco-py.git
git checkout master             # mujoco v1.50

cd mujoco-py && python setup.py install

And you can run this script in python to verify

import gym
env = gym.make('Hopper-v1')
print(env.observation_space)
print(env.action_space)
env.reset()
for _ in range(100):
    env.render()
    env.step(env.action_space.sample()) # take a random action

@mixuala I'm on OSX 10.11.3 and I'm having the same error even after following your steps.

Update: I did get it to work by but then got hit by issue #80 specifically this after trying to solve it :

mixuala commented 7 years ago

did you install mujoco-py from the cloned git repo? I did not install using pip

tshrjn commented 7 years ago

Yes, I did but that did not help. Finally resolved all problems by installing 0.5.7 via pip.

pip install mujoco-py==0.5.7
richardrl commented 6 years ago

Although I can install .5.7, functions are missing. For example, 'load_model_from_path' which is only present in latest mujoco_py 1.5. Anyone get that working?

erwincoumans commented 6 years ago

What are the up-to-date instructions to install mujoco_py on Mac OSX (my OSX version is 10.13.4, but errors are the same, and tried various gcc versions /cymj_macextensionbuilder.so, 2): Symbol not found: _GOMP_parallel)

mixuala commented 6 years ago

I just installed again on a new Mac-mini with the latest 10.13. It worked fine according to the script I posted above. But I had to use the 1.3.1 version—1.5.0 did not work.

nemanja-rakicevic commented 6 years ago

check if this helps https://github.com/openai/mujoco-py/issues/80#issuecomment-366438347

f1recracker commented 6 years ago

If it helps, I resolved the Symbol not found: _GOMP_parallel) problem by using Python 3.5.3 (I was actually using Python 3.6 all this while which is currently not supported). I was also able to install mujoco_py directly from pip (MacOS 10.13.3, conda).

azmosavi commented 6 years ago

@mixuala Thanks it was really helpful.

billtubbs commented 6 years ago

@mixuala's install script worked for me on OS X 10.13.4 with python 3.6.5, gym 0.10.5, and mujoco 1.50.1.56. Although the coursework I am doing says I have to install 1.3.1.

Note that we use version 1.31 and not the latest version 1.50. The python interface to mujoco bundled with OpenAI gym is also compatible with this version of mujoco.

See course material here. Does anyone know if this is still an issue or whether it will now work with 1.5.1? I will try it...

zjzijielu commented 6 years ago

Hi @billtubbs, I'm also struggling with the same issue. Did you get it to work with mujoco 1.5?
