polars.DataFrame.to_numpy

DataFrame.to_numpy() → ndarray[Any, Any]

Convert DataFrame to a 2D NumPy array.

This operation clones data.

Notes

If you’re attempting to convert Utf8 to an array you’ll need to install pyarrow.

Examples

>>> df = pl.DataFrame(
...     {"foo": [1, 2, 3], "bar": [6, 7, 8], "ham": ["a", "b", "c"]}
... )
>>> numpy_array = df.to_numpy()
>>> type(numpy_array)
<class 'numpy.ndarray'>
