Installation

First, you need to install Polars.

Then, you’ll need to install polars-xdt:

pip install polars-xdt

Then, if you can run

import polars as pl
import polars_xdt  # noqa: F401

print(pl.col('a').xdt)

and see something like <polars_xdt.ExprXDTNamespace at 0x7f5bc943fc10>, it means installation all worked correctly!
