lance-tensorflow 0.1.0

TensorFlow integration for Lance datasets

lance-tensorflow

TensorFlow integration for Lance datasets.

This package provides a small Python adapter that exposes Lance datasets as tf.data.Dataset pipelines. The core Lance format and Python bindings remain in the pylance package.

Install

pip install lance-tensorflow

TensorFlow support is currently targeted at Linux.

Usage

from lance_tensorflow import from_lance

ds = from_lance(
    "s3://bucket/path",
    columns=["image", "label"],
    filter="split = 'train'",
    batch_size=256,
)

for batch in ds:
    print(batch["label"])

If you want the tf.data.Dataset.from_lance convenience methods, register them explicitly:

import tensorflow as tf
import lance_tensorflow

lance_tensorflow.register_tensorflow_dataset()

ds = tf.data.Dataset.from_lance("s3://bucket/path")
