Mujoco-py: Unknow error installing using Python3 and Anaconda3 on Linux

Created on 28 Jun 2017  Â·  15Comments  Â·  Source: openai/mujoco-py

After coming to know that this is not available in Python2, I did fresh install of Anaconda3, set up python3 environment and tried installing.
However, it throws errors such as:

TypeError: can't pickle Cython.Compiler.Code.FunctionState objects

and

Command "/home/him/anaconda3/envs/tensorflow/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-j00wxlw4/mujoco-py/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('rn', 'n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-dstl1tts-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-j00wxlw4/mujoco-py/

Attaching hereby the full installation log file and hardware configuration for reference.

install_log.txt

Edit: I was getting very similar errors after modifying the source code to make it compatible for Python2 too! Here is python2 install log.
python2_install_log.txt
(I really don't want you to bug you with python2 thing, since its now mentioned there that python2 isn't supported. Still I just want to see if it's not the problem of python2. If it's the case, I will make it compatible for python2.)

Finally, After a lot of trying, I was able to install the mujoco_py lib in python3 global as well as Anacoda environment, but not using pip, instead using python setup.py install command.

There are some observations for _an end user_ that I would like to make, that might seem to be helpful:

  1. DO NOT try building mujoco_py using python2. There is some bug in cython, which got rectified in python versions 3.5+
  2. Set Up exact same environment as mentioned by the authors. I even failed with python 3.6.2. I don't know why!
  3. Pip/Pip3 installation can fail. It did in my case all the time. So instead use python setup.py install command. This holds true for both Anaconda environment as well as global environment. For global, ofcourse u will need root access.
  4. For building with CPU support, make sure you have the libosmesa6-dev library installed.

Some _Observations/Request to the authors_:

  1. Please include patchelf==0.9 and mention autoreconf as requirements in your documentation for building for GPU. 0.8 version was abruptly failing due to not having required functions.
  2. In Builder.py, instead of sys.platform == 'linux', please check for sys.platform.startswith("linux"). My Laptop shows 'linux2' as its platform.
  3. The GPU OpenGL library address (/usr/local/nvidia/) is for older model. So for new GPUs, please add a check to /usr/lib/nvidia-*/ or something similar. My laptop had the libs at /usr/lib/nvidia-375/. My GPU being GTX960M.

Thanks

The Dockerfile can provide a good reference for what is needed in an otherwise-empty linux machine.

Thanks @hmishra2250, we'll be tracking support for Python 3.6 in #52. Would you mind opening a PR for the other issues you mentioned? Thanks!

@hmishra2250 Thank you so much for your comment! I ran into the same problem today and your comment saved me bunch of time.

Here is the Makefile that does the job:

  • [x] use 3.5.2 with conda
  • [x] clone and install
  • [x] use Dockerfile as a reference for the dependencies.

can anyone give me a specific procedure to install the mujoco_py which can be used well. After several days trying, I am tatally lost.

taosheng1993 picture taosheng1993 on 3 Jul 2017

Yeah! I have mujoco_py working with me.
So the above procedure mentioned by @episodeyang is for Linux. It'll work for sure, the only problem u will encounter is the MjViewer class will give seg fault or some GL init error. Check this issue.
So to make it work, switch to windows, install using the exact same specifications mentioned as in this and python==3.5.2 file, and then install mujoco_py (try with pip, if that fails, try installing using python setup.py install after cloning the repo to the local system). You can also refer to this appveyor file for instructions related to how to install.
In windows, you will have the advantage of the viewer working well and good. So prefer windows for now.

_TL;DR_

  1. Use Windows (suggested for Viewer to work)
  2. Install python==3.5.2
  3. Install all dependencies and dev dependencies (if required).
  4. Install mujoco_py using pip command and if that fails, use the cloned repo and install using setup.py (python setup.py install).

Good luck!

Hi,I am still a little confused. what do you mean referring to this this appveyor file for instructions? I have no idea how to use the yml file? plz give me some clues.

Hey there, Your script allowed me to install it on fedora but there's a problem it still gives me an error when I import it with python.

fatal error: mjmodel.h: No such file or directory
 #include "mjmodel.h"
DakshMiglani picture DakshMiglani on 4 Jul 2017

The header files (mjmodel.h, etc) have to be installed separately from this python package. Make sure you've got those: https://github.com/openai/mujoco-py#install-mujoco

Hello everyone,
I tried to use the series of commands shared by @epidoseyang with slight modifications as:

sudo bash ./Anaconda3-4.4.0-Linux-x86_64.sh
source ~/.bashrc
# install-python3.5.2:
    conda create --name ml python=3.5.2
    source activate ml (tried without this command but got the same results)
# get-mujoco: (Done offline)
# install-mujoco-dependencies:
    sudo apt-get update -q
    DEBIAN_FRONTEND=noninteractive sudo apt-get install -y \
    curl \
    git \
    libgl1-mesa-dev \
    libgl1-mesa-glx \
    libosmesa6-dev \
    python3-pip \
    python3-numpy \
    python3-scipy \
    unzip \
    vim \
    wget \
    xpra \
    xserver-xorg-dev
    sudo apt-get clean
    sudo rm -rf /var/lib/apt/lists/*
# install patch
    sudo curl -o /usr/local/bin/patchelf https://s3-us-west-2.amazonaws.com/openai-sci-artifacts/manual-builds/patchelf_0.9_amd64.elf
    sudo chmod +x /usr/local/bin/patchelf

# install-mujoco:
    rm -rf mujoco-py
    git clone https://github.com/openai/mujoco-py.git
    bash -c "cd mujoco-py && source activate ml && python setup.py install"

I used Anaconda3 with python 3.5.2 on Ubuntu 16.04. I tried to use both mj150 and mj131 version but am getting same errors at "python setup.py install" command. Can someone please help me with the possible reasons. I would really appreciate any help I can get. I have attached the text file with output messages from installation process.

After this, I still tried to run the example file "body_interaction.py" and it threw errors as:

@episodeyang: Thank you so much for the response. I tried your new makefile multiple times but unfortunately received similar errors. It starts throwing errors when it is installing mujoco_py. I am attaching the initial errors. I am totally stuck in installation of mujoco-py and would really appreciate if you/ anyone can help me further with the troubleshooting.

@puneetsinghal the illegal instruction might mean your CPU is missing AVX instructions.

Unfortunately AVX is required for mujoco 1.50, though it's only likely to be on processors from 2010 or later.

@episodeyang I followed your script to install mujoco-py on my Linux Mint, which is based on Ubuntu 16.04. Upon successful installation of mujoco-py, when I try the following code:

import gym
env = gym.make('Humanoid-v1')
env.reset()
env.render()

I get the following error:

During handling of the above exception, another exception occurred:

Would you know how to resolve this?
