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

         On Windows systems, by default,Isaac Sim is installed in the directory
         ``%USERPROFILE%\AppData\Local\ov\pkg\isaac_sim-*``, with ``*`` corresponding to the Isaac Sim version.

Verifying the Isaac Sim installation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To avoid the overhead of finding and locating the Isaac Sim installation
directory every time, we recommend exporting the following environment
variables to your terminal for the remaining of the installation instructions:

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

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

      .. code:: bash

         # Isaac Sim root directory
         export ISAACSIM_PATH="${HOME}/.local/share/ov/pkg/isaac-sim-4.2.0"
         # Isaac Sim python executable
         export ISAACSIM_PYTHON_EXE="${ISAACSIM_PATH}/python.sh"

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

      .. code:: batch

         :: Isaac Sim root directory
         set ISAACSIM_PATH="%USERPROFILE%\AppData\Local\ov\pkg\isaac-sim-4.2.0"
         :: Isaac Sim python executable
         set ISAACSIM_PYTHON_EXE="%ISAACSIM_PATH:"=%\python.bat"


For more information on common paths, please check the Isaac Sim
`documentation <https://docs.omniverse.nvidia.com/isaacsim/latest/installation/install_faq.html#common-path-locations>`__.


-  Check that the simulator runs as expected:

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

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

         .. code:: bash

            # note: you can pass the argument "--help" to see all arguments possible.
            ${ISAACSIM_PATH}/isaac-sim.sh

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

         .. code:: batch

            :: note: you can pass the argument "--help" to see all arguments possible.
            %ISAACSIM_PATH%\isaac-sim.bat


-  Check that the simulator runs from a standalone python script:

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

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

         .. code:: bash

            # checks that python path is set correctly
            ${ISAACSIM_PYTHON_EXE} -c "print('Isaac Sim configuration is now complete.')"
            # checks that Isaac Sim can be launched from python
            ${ISAACSIM_PYTHON_EXE} ${ISAACSIM_PATH}/standalone_examples/api/isaacsim.core.api/add_cubes.py

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

         .. code:: batch

            :: checks that python path is set correctly
            %ISAACSIM_PYTHON_EXE% -c "print('Isaac Sim configuration is now complete.')"
            :: checks that Isaac Sim can be launched from python
            %ISAACSIM_PYTHON_EXE% %ISAACSIM_PATH%\standalone_examples\api\isaacsim.core.api\add_cubes.py


.. caution::

   If you have been using a previous version of Isaac Sim, you need to run the following command for the *first*
   time after installation to remove all the old user data and cached variables:

   .. tab-set::

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

      	.. code:: bash

      		${ISAACSIM_PATH}/isaac-sim.sh --reset-user

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

         .. code:: batch

            %ISAACSIM_PATH%\isaac-sim.bat --reset-user


If the simulator does not run or crashes while following the above
instructions, it means that something is incorrectly configured. To
debug and troubleshoot, please check Isaac Sim
`documentation <https://docs.omniverse.nvidia.com/dev-guide/latest/linux-troubleshooting.html>`__
and the
`forums <https://docs.omniverse.nvidia.com/isaacsim/latest/isaac_sim_forums.html>`__.


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

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-4.2.0 _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-4.2.0


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.

.. note::

   If you use Conda, we recommend using `Miniconda <https://docs.anaconda.com/miniconda/miniconda-other-installer-links/>`_.

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 'env_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 'env_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 env_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`` 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``.

Verifying the Isaac Lab installation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To verify that the installation was successful, run the following command from the
top of the repository:

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

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

      .. code:: bash

         # Option 1: Using the isaaclab.sh executable
         # note: this works for both the bundled python and the virtual environment
         ./isaaclab.sh -p scripts/tutorials/00_sim/create_empty.py

         # Option 2: Using python in your virtual environment
         python scripts/tutorials/00_sim/create_empty.py

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

      .. code:: batch

         :: Option 1: Using the isaaclab.bat executable
         :: note: this works for both the bundled python and the virtual environment
         isaaclab.bat -p scripts\tutorials\00_sim\create_empty.py

         :: Option 2: Using python in your virtual environment
         python scripts\tutorials\00_sim\create_empty.py


The above command should launch the simulator and display a window with a black
viewport. You can exit the script by pressing ``Ctrl+C`` on your terminal.
On Windows machines, please terminate the process from Command Prompt using
``Ctrl+Break`` or ``Ctrl+fn+B``.
