Environment Identification

This repository collects the work conducted by a collaboration between UniSa, PoliMi and IDSIA. The repository is thought for students with the aim to provide an environment for the development of master theses projects and some research activities.

Getting Started

This section explains how to setup the environment needed to launch the demos. First, MuJoCo needs to be installed, then some preliminary packages are required for the virtual environment creation.

Install MuJoCo 2.1.0

In order to install MuJoCo you need to:

1. Create a hidden folder:

   cd
   mkdir .mujoco

2. Download MuJoCo library

   cd .mujoco
   wget https://mujoco.org/download/mujoco210-linux-x86_64.tar.gz

3. Extract the MuJoCo downloaded library into the hidden folder .mujoco

   tar -xf mujoco210-linux-x86_64.tar.gz -C .
   rm mujoco210-linux-x86_64.tar.gz

4. Add these lines to the .bashrc file:

   export LD_LIBRARY_PATH=$HOME/username/.mujoco/mujoco210/bin #substitute username with your username
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia #if nvidia graphic
   export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libGLEW.so
   export PATH="$LD_LIBRARY_PATH:$PATH"

5. Source the .bashrc file:

   cd
   source .bashrc

6. Test the installation:

   cd ~/.mujoco/mujoco210/bin
   ./simulate ../model/humanoid.xml

Prerequisites

You will need Pip for the virtual environment packages installation, venv for the virtual environment and some other packages as prerequisites for Mujoco-Py. sudo can be needed for some installations.

• Pip

  apt install pip
  

• Packages needed for Mujoco-Py

  apt install libosmesa6-dev libgl1-mesa-glx libglfw3
  apt install patchelf gcc
  apt install python3-dev build-essential libssl-dev libffi-dev libxml2-dev
  apt install libxslt1-dev zlib1g-dev libglew-dev
  

• Python-venv

  apt install python3.8-venv
  

Setting up the virtual environment

Create a venv and activate it

python3 -m venv venv
source venv/bin/activate

Install via pip the required packages into the virtual environment

python3 -m pip install -r requirements.txt

Clone environment_identification
