Learn more. The snowflake-ml-python Python package also includes the ML Modeling APIs, which support data preprocessing, feature engineering, and model training in Snowflake using popular machine learning frameworks, such as scikit-learn, xgboost, lightgbm, and pytorch. The value in this field is case-sensitive. local_time, CASE WHEN T2. For case-insensitive matching, use ILIKE instead. Ask Question Asked 3 years, 4 months ago.
