Open in Colab Read in the docs View on GitHub

Colab runs it in your browser. If it calls a model provider, it asks for that provider's API key in a cell.

How it works

You use pxt.create_table() with a source parameter to create a table from a Parquet file. Pixeltable infers column types from the Parquet schema automatically.

What it covers

Import Parquet files directly into tables
Export tables to Parquet for external tools
Handle schema type overrides

What it uses

Install: terminal
pip install pixeltable pyarrow pandas
Pixeltable calls: pxt.create_table()add_computed_column()
