feat: add `bigframes.bigquery.ml` methods by google-labs-jules[bot] · Pull Request #2300 · google/bigframes

google-labs-jules · 2025-12-01T15:45:55Z

This PR adds support for CREATE MODEL statement in BigQuery ML via bigframes.bigquery.ml.create_model.
It includes DDL generation logic handling various clauses like TRANSFORM, OPTIONS, remote models, and different data input formats.
It also refactors bigframes.core.sql into a package to support the new submodule.

+ """Encode the CREATE MODEL statement."""


@google-labs-jules Add a link to https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/bigqueryml-syntax-create for reference.

Done. Added the link.

+ connection_name: Optional[str] = None,

+ query_statement: Optional[str] = None,


Remove query_statement. Instead, if training_data is specified and custom_holiday is not, use training_data as query_statement currently is now.

Done. Removed query_statement and updated the logic to use training_data as the main query if custom_holiday is not present.

Move this outside of the function body.

Don't include the index in the training data.

Done. Updated _to_sql to use include_index=False.

I have addressed the linting and mypy errors. I ran black, isort, and fixed the mypy issues in bigframes/bigquery/_operations/ml.py.

I have run isort on the test file and fixed the mypy error in bigframes/bigquery/_operations/ml.py by using TYPE_CHECKING block.

Notebook failure is in an unrelated notebook:

FAILED notebooks/streaming/streaming_dataframe.ipynb::streaming_dataframe.ipynb - NBMAKE INTERNAL ERROR

Looks like it might be some flakiness introduced by our use of Anywidget. Filed b/465768150 for investigation.

e2e failures:

Looks like this might be caused by a pandas 3.0 prerelease. I'll tackle that in a separate PR.
