Pyarrow will become a required dependency of pandas in the next major release of pandas (pandas 3.0)

Pyarrow is set to become a required dependency of pandas in the upcoming major release, pandas 3.0. This change aims to enhance the performance of data types, especially with the introduction of the Arrow string type, and improve interoperability with other libraries. However, if you encounter the error message “Pyarrow not found on your system” after the update, don’t worry—there’s a simple solution.

Understanding the Change

The decision to make Pyarrow a mandatory dependency in pandas 3.0 is driven by the desire to leverage more performant data types and improve compatibility with other data science and analytics libraries. The Arrow string type, in particular, offers better performance and memory efficiency, contributing to an overall enhanced user experience.

Dealing with Installation Issues

After the upgrade to pandas 3.0, some users might encounter the error message stating that Pyarrow is not installed on their system. If you face this issue, there’s no need to panic. The solution is straightforward: install Pyarrow using the following pip command.

pip install pyarrow 

Executing this command will resolve the problem and ensure that Pyarrow is properly installed on your system, allowing pandas 3.0 to function seamlessly.

Why Pyarrow?

Pyarrow is a powerful library that provides a cross-language platform for in-memory data representation. By making it a required dependency, pandas aims to tap into the efficiency and capabilities offered by Pyarrow, especially concerning the Arrow string type. This strategic integration enhances the overall performance of pandas and enables smoother collaboration with other data-oriented tools and frameworks.


As pandas evolves with each major release, embracing new dependencies and technologies is crucial for staying at the forefront of data science and analysis. The decision to make Pyarrow a required dependency in pandas 3.0 reflects the project’s commitment to performance improvements and enhanced interoperability.

If you encounter the Pyarrow installation issue, the provided pip command offers a quick and effective resolution. Stay informed about these changes, embrace the updates, and enjoy a more efficient and powerful pandas experience with version 3.0.
