Can I use runcell with Jupyter Notebook?
**No**, runcell currently only supports **JupyterLab 4.4.0+**. The classic Jupyter Notebook interface is not supported. To switch from Jupyter Notebook to JupyterLab: ``` pip install jupyterlab jupyter lab # instead of jupyter notebook ```
What's the difference between the installation methods?
- **pip from PyPI** (recommended): Automatic dependency management, always latest version - **conda + pip**: Best for conda users, maintains environment isolation - **uv**: Fastest installation, good for CI/CD environments - **Manual wheel**: For offline installations or specific version requirements
Why use pip within conda environments?
While conda is excellent for environment management, pip provides better compatibility for Python wheel files and ensures proper installation of JupyterLab extensions.
How do I verify the installation worked?
1. Start JupyterLab: `jupyter lab` 2. Check the right sidebar for the runcell extension 3. The extension should appear as an icon in the sidebar 4. Click on it to access runcell functionality
