Ray's web UI requires **Python 3**. To enable the web UI to work, install these
Python packages.
.. code-block:: bash
pip install aioredis asyncio websockets
Then install `Polymer`_, which also requires `Node.js`_ and `Bower`_.
.. _`Polymer`: https://www.polymer-project.org/1.0/docs/tools/polymer-cli
.. _`Node.js`: https://nodejs.org/en/download/
.. _`Bower`: http://bower.io/#install-bower
Once you've installed Polymer, run the following.
.. code-block:: bash
cd ray/webui
bower install
Then while Ray is running, you should be able to view the web UI at
``http://localhost:8080``.

When you want to stop the Ray processes, run `./ray/scripts/stop_ray.sh`
on each node.
### Using the Web UI on a Cluster
If you followed the instructions for setting up the web UI, then
`./ray/scripts/start_ray.sh --head` will attempt to start a Python 3 webserver
on the head node. In order to view the web UI from a machine that is not part of
the cluster (like your laptop), you can use SSH port forwarding. The web UI
requires ports 8080 and 8888, which you can forward using a command like the
following.
```
ssh -L 8080:localhost:8080 -L 8888:localhost:8888 ubuntu@<head-node-public-ip>
```
Then you can view the web UI on your laptop by navigating to
`http://localhost:8080` in a browser.
#### Troubleshooting the Web UI
Note that to use the web UI, additional setup is required. In particular, you
must be using Python 3 or you must at least have `python3` on your path.
If the web UI doesn't work, it's possible that the web UI processes were never
started (check `ps aux | grep polymer` and `ps aux | grep ray_ui.py`). If they
were started, see if you can fetch the web UI from within the head node (try
`wget http://localhost:8080` on the head node).
