Panel: The powerful data exploration & web app framework for Python

Panel is an open-source Python library that lets you easily build powerful tools, dashboards and complex applications entirely in Python. It has a batteries-included philosophy, putting the PyData ecosystem, powerful data tables and much more at your fingertips. High-level reactive APIs and lower-level callback based APIs ensure you can quickly build exploratory applications, but you aren't limited if you build complex, multi-page apps with rich interactivity. Panel is a member of the HoloViz ecosystem, your gateway into a connected ecosystem of data exploration tools.

Installation Errors

Common errors when installing panel with pip.

ModuleNotFoundError: No module named 'panel'

Cause: The package is not installed in the current Python environment.

Fix: Run pip install panel. If using a virtual environment, ensure it is activated first.

ModuleNotFoundError: No module named 'panel' (installed but still failing)

Cause: pip installed the package into a different Python than the one running your script.

Fix: Use python -m pip install panel to install into the interpreter you are running.

ImportError: cannot import name 'X' from 'panel'

Cause: The function or class does not exist in the installed version.

Fix: Check the version with pip show panel and upgrade with pip install --upgrade panel.

pip: command not found

Cause: pip is not in PATH or Python was not added to PATH during installation.

Fix: Try python -m pip install panel. On macOS/Linux try pip3.

PermissionError: [Errno 13] Permission denied

Cause: No write access to the system Python package directory.

Fix: Use a virtual environment, or add --user: pip install --user panel

SSL: CERTIFICATE_VERIFY_FAILED

Cause: pip cannot verify PyPI's SSL certificate — common behind corporate proxies.

Fix: Try: pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org panel

MemoryError when loading data

Cause: Dataset is too large to fit in RAM.

Fix: Read in chunks, filter columns on load, or consider Polars/Dask for out-of-core processing.
