How to Install Dash in Kaggle

Dash is a popular Python framework for building interactive web applications. Kaggle kernels (notebooks) operate in a cloud-based environment, which provides a variety of pre-installed libraries. However, Dash is not installed by default. You'll need to install it manually using Kaggle's inbuilt terminal or directly in a notebook cell.

Install Dash Library in Kaggle using pip

Kaggle allows you to install additional Python packages using pip. To install Dash, you can execute the following command:

In a Notebook Cell:

!pip install dash

In the Kaggle Terminal:

1. Click on the "+" button next to "Files" in the sidebar.
2. Select "New Terminal" to open a terminal window.
3. Run the following command:

pip install dash

This will install Dash and its dependencies, including Flask, Plotly, and dash-html-components.

Verify the Installation

To confirm that Dash is successfully installed, you can check its version. Run the following command in a notebook cell:

Output:

Dash version: 2.18.2

If the version is displayed without errors, the installation was successful.

Create a Simple Dash Application

Here’s a quick example to test Dash in Kaggle:

1. Write the Dash Code

Create a simple Dash application to display a line chart.

2. Run the Application

In Kaggle, running Dash directly requires additional configuration to access the app via its external URL.

To simplify, use the following:

• Run the app with ngrok: Kaggle doesn’t provide direct access to custom web servers, but tools like ngrok can expose your app.
• Save Outputs: Use Dash’s static export capabilities to generate visualizations and embed them in your notebook.
