CML Streamlit

A minimal example of a Streamlit application running as a CML or CDSW Application. We'll refer only to CML from here on out, but the instructions are exactly the same for CDSW.

Instructions

Create a new CML project from git, or otherwise clone this repo into a CML project.

Open a Python 3 session in CML.

Install Streamlit by running !pip3 install -r requirements.txt in the Python REPL to the right.

There are two scripts relevant to running Streamlit as a CML Application:

app.py        # this is the streamlit app itself
launcher.py   # this is the script we pass to the CML Application to launch our app

Create a new Application by navigating to the Applications pane on the left. Fill in the details similarly to the screenshot below.

Once the Application has been created, you can launch it from the Applications pane. This should open a browser window, with a Streamlit application running at a URL something like streamlit-demo.cml.your-organization.com.

If everything worked, you should see something like this:

To develop the Streamlit app, return to the Python 3 session, and hack away. Hot reloading of the app on save should work.

Happy hacking!
