Installing Isaac Lab
--------------------

Cloning Isaac Lab
~~~~~~~~~~~~~~~~~

.. note::

   We recommend making a `fork <https://github.com/isaac-sim/IsaacLab/fork>`_ of the Isaac Lab repository to contribute
   to the project but this is not mandatory to use the framework. If you
   make a fork, please replace ``isaac-sim`` with your username
   in the following instructions.

Clone the Isaac Lab repository into your workspace:

.. tab-set::

   .. tab-item:: SSH

      .. code:: bash

         git clone git@github.com:isaac-sim/IsaacLab.git

   .. tab-item:: HTTPS

      .. code:: bash

         git clone https://github.com/isaac-sim/IsaacLab.git


.. note::
   We provide a helper executable `isaaclab.sh <https://github.com/isaac-sim/IsaacLab/blob/main/isaaclab.sh>`_ that provides
   utilities to manage extensions:

   .. tab-set::

Creating the Isaac Sim Symbolic Link
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Set up a symbolic link between the installed Isaac Sim root folder
and ``_isaac_sim`` in the Isaac Lab directory. This makes it convenient
to index the python modules and look for extensions shipped with Isaac Sim.

.. tab-set::
   :sync-group: os

   .. tab-item:: :icon:`fa-brands fa-linux` Linux
      :sync: linux

      .. code:: bash

         # enter the cloned repository
         cd IsaacLab
         # create a symbolic link
         ln -s path_to_isaac_sim _isaac_sim
         # For example: ln -s /home/nvidia/.local/share/ov/pkg/isaac-sim-4.1.0 _isaac_sim

   .. tab-item:: :icon:`fa-brands fa-windows` Windows
      :sync: windows

      .. code:: batch

         :: enter the cloned repository
         cd IsaacLab
         :: create a symbolic link - requires launching Command Prompt with Administrator access
         mklink /D _isaac_sim path_to_isaac_sim
         :: For example: mklink /D _isaac_sim C:/Users/nvidia/AppData/Local/ov/pkg/isaac-sim-4.1.0


Setting up the conda environment (optional)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. attention::
   This step is optional. If you are using the bundled python with Isaac Sim, you can skip this step.

The executable ``isaaclab.sh`` automatically fetches the python bundled with Isaac
Sim, using ``./isaaclab.sh -p`` command (unless inside a virtual environment). This executable
behaves like a python executable, and can be used to run any python script or
module with the simulator. For more information, please refer to the
`documentation <https://docs.omniverse.nvidia.com/isaacsim/latest/manual_standalone_python.html#isaac-sim-python-environment>`__.

Although using a virtual environment is optional, we recommend using ``conda``. To install
``conda``, please follow the instructions `here <https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html>`__.
In case you want to use ``conda`` to create a virtual environment, you can
use the following command:

.. tab-set::
   :sync-group: os

   .. tab-item:: :icon:`fa-brands fa-linux` Linux
      :sync: linux

      .. code:: bash

         # Option 1: Default name for conda environment is 'isaaclab'
         ./isaaclab.sh --conda  # or "./isaaclab.sh -c"
         # Option 2: Custom name for conda environment
         ./isaaclab.sh --conda my_env  # or "./isaaclab.sh -c my_env"

   .. tab-item:: :icon:`fa-brands fa-windows` Windows
      :sync: windows

      .. code:: batch

         :: Option 1: Default name for conda environment is 'isaaclab'
         isaaclab.bat --conda  :: or "isaaclab.bat -c"
         :: Option 2: Custom name for conda environment
         isaaclab.bat --conda my_env  :: or "isaaclab.bat -c my_env"


If you are using ``conda`` to create a virtual environment, make sure to
activate the environment before running any scripts. For example:

.. code:: bash

   conda activate isaaclab  # or "conda activate my_env"

Once you are in the virtual environment, you do not need to use ``./isaaclab.sh -p`` / ``isaaclab.bat -p``
to run python scripts. You can use the default python executable in your environment
by running ``python`` or ``python3``. However, for the rest of the documentation,
we will assume that you are using ``./isaaclab.sh -p`` / ``isaaclab.bat -p`` to run python scripts. This command
is equivalent to running ``python`` or ``python3`` in your virtual environment.


Installation
~~~~~~~~~~~~

-  Install dependencies using ``apt`` (on Linux only):

   .. code:: bash

      # these dependency are needed by robomimic which is not available on Windows
      sudo apt install cmake build-essential

- Run the install command that iterates over all the extensions in ``source/extensions`` directory and installs them
  using pip (with ``--editable`` flag):

.. tab-set::
   :sync-group: os

   .. tab-item:: :icon:`fa-brands fa-linux` Linux
      :sync: linux

      .. code:: bash

         ./isaaclab.sh --install # or "./isaaclab.sh -i"

   .. tab-item:: :icon:`fa-brands fa-windows` Windows
      :sync: windows

      .. code:: batch

         isaaclab.bat --install :: or "isaaclab.bat -i"

.. note::

   By default, the above will install all the learning frameworks. If you want to install only a specific framework, you can
   pass the name of the framework as an argument. For example, to install only the ``rl_games`` framework, you can run

   .. tab-set::
      :sync-group: os

      .. tab-item:: :icon:`fa-brands fa-linux` Linux
         :sync: linux

         .. code:: bash

            ./isaaclab.sh --install rl_games  # or "./isaaclab.sh -i rl_games"

      .. tab-item:: :icon:`fa-brands fa-windows` Windows
         :sync: windows

         .. code:: batch

            isaaclab.bat --install rl_games :: or "isaaclab.bat -i rl_games"

   The valid options are ``rl_games``, ``rsl_rl``, ``sb3``, ``skrl``, ``robomimic``, ``none``.
