At the time of writing this post, we are in the process of releasing pandas 2. The project has a large number of users, and it's used in production quite widely by personal and corporate users. This large use based forces us to be conservative and make us avoid most big changes that would break existing pandas code, or would change what users already know about pandas. So, most changes to pandas, while they are important, they are quite subtle. Most of our changes are bug fixes, code improvements and clean up, performance improvements, keep up to date with our dependencies, small changes that make the API more consistent, etc.

The new release represents a significant milestone in data processing efficiency and offers best practices for optimizing your code. Providing intuitive data structures and functions, Pandas enables users to effortlessly work with structured data, streamlining the process of cleaning, analyzing, and visualizing datasets. The much-anticipated Pandas 2. This major update, years in the making, is the most significant overhaul since the library's inception. While most existing Pandas code will likely run as before and the changes might not be immediately apparent, the new version introduces substantial improvements. The shift from NumPy to Apache Arrow for data representation addresses many limitations and boosts the performance of numerous Pandas tasks.

Pandas 2.0

It aims to be the fundamental high-level building block for doing practical, real world data analysis in Python. It is already well on its way towards this goal. The list of changes to pandas between each release can be found here. See the full installation instructions for minimum supported versions of required, recommended and optional dependencies. To install pandas from source you need Cython in addition to the normal dependencies above. Cython can be installed from PyPI:. In the pandas directory same one where you found this file after cloning the git repo , execute:. See the full instructions for installing from source.

Nov 10, But things are actually more complex. The shift from NumPy to Apache Arrow for data representation addresses many limitations and boosts the performance of numerous Pandas tasks. For the case of floating point numbers, the internal CPU representation is more complex, and there are actually some sentinel values already defined in the IEEE standard, which CPUs implement, and are able to deal with efficiently. The PyArrow-specific extension array supports all other PyArrow dtypes on top of it. Sep 20, Not as stable or mature yet, but it's faster and more memory efficient than pandas. But when performance is important, data types are represented in the CPU representation, and can't be mixed with other types. When migrating to Pandas 2. Mar 18, Patrick Hoefler. Additionally, many operations now properly operate on the nullable arrays which maintains the appropriate dtype when returning the result. Jun 22, All numeric indexes are now represented as Index with an associated dtype, e. Jun 18,

We are pleased to announce the release of pandas 2. This release includes some new features, bug fixes, and performance improvements. We recommend that all users upgrade to this version.

I need to build a pipeline to load some data from my company data warehouse, transform it, compute some analytics, and then export an automatically generated long report with the analytics. As a note, pandas has its own implementation of an equivalent categorical type backed by NumPy arrays. Or if Polars could understand NumPy directly. No items found. The new release represents a significant milestone in data processing efficiency and offers best practices for optimizing your code. In part II we will show how to implement pandas extensions by using Arrow. This is visible through a bunch of significant performance improvements:. Another important milestone was the implementation of a string data type based on Arrow that started in This section will provide a short guide on how to address these issues and help you migrate your code smoothly. This has two main implications. Mar 2, Jun 22, Dec 26, We are pleased to announce a release candidate for pandas 2. Dec 24,
