4. Running the Streamlit App from the Terminal🖥️
Getting Started with the Command Line 🚀
For those unfamiliar, the terminal (or command line) is a text-based interface to operate your computer. It's a powerful tool that allows developers to run scripts, utilities, and manage files.
Launching the App 🌐
To run the Streamlit app, you need to use the terminal. Follow the steps below:
Navigate to the Directory: Before running the app, ensure you're in the correct directory (folder) where your Streamlit script is located. Use the cd command to change directories: cd path/to/your/folder
Run the Streamlit App: Once in the correct directory, you can run the app with the following streamlit run app.py Replace app.py with the name of your Streamlit script file.
Accessing the App: After running the command, Streamlit will provide a local URL in the terminal (typically http://localhost:8501). Click on it or copy-paste it into your web browser to interact with the app.
Troubleshooting 🛠️
Port Issues: If the default port (8501) is occupied, Streamlit will try to use the next available port. Make sure to check the terminal for the correct URL.
Dependencies: Ensure all necessary libraries are installed. If you encounter an error related to a missing library, you can install it using pip: pip install library_name
Closing the App 🚫
To stop the Streamlit app, go back to the terminal and press CTRL+C (or CMD+C on macOS). This command will halt the app and return control to the terminal.
