1.1.1

1.1.1

Bug Fixes

• Model Registry: The predict target method on registered models is now compatible with unsupervised estimators.
• Model Development: Fix confusion_matrix incorrect results when the row number cannot be divided by the batch size.

Behavior Changes

New Features

• Introduced passthrough_col param in Modeling API. This new param is helpful in scenarios
  requiring automatic input_cols inference, but need to avoid using specific
  columns, like index columns, during training or inference.

1.1.0

1.1.0

Bug Fixes

• Model Registry: Fix panda dataframe input not handling first row properly.
• Model Development: OrdinalEncoder and LabelEncoder output_columns do not need to be valid snowflake identifiers. They
  would previously be excluded if the normalized name did not match the name specified in output_columns.

Behavior Changes

New Features

• Model Registry: Add support for invoking public endpoint on SPCS service, by providing a "enable_ingress" SPCS
  deployment option.
• Model Development: Add support for distributed HPO - GridSearchCV and RandomizedSearchCV execution will be
  distributed on multi-node warehouses.

1.0.12

1.0.12

Bug Fixes

• Model Registry: Fix regression issue that container logging is not shown during model deployment to SPCS.
• Model Development: Enhance the column capacity of OrdinalEncoder.
• Model Registry: Fix unbound `batch_size`` error when deploying a model other than Hugging Face Pipeline
  and LLM with GPU on SPCS.

Behavior Changes

  >=x.y,<(x+1).
• Model Registry: Python with different patchlevel but the same major and minor will not result a warning when loading
  the model via Model Registry and would be considered to use when deploying to SPCS.
• Model Registry: When logging a snowflake.ml.model.models.huggingface_pipeline.HuggingFacePipelineModel object,
  versions of local installed libraries won't be picked as dependencies of models, instead it will pick up some pre-
  defined dependencies to improve user experience.

1.0.10

1.0.10

Behavior Changes

• Model Development: precision_score, recall_score, f1_score, fbeta_score, precision_recall_fscore_support,
  mean_absolute_error, mean_squared_error, and mean_absolute_percentage_error metric calculations are now distributed.

• Model Development: Fix an issue that alias definitions cause SnowparkSQLUnexpectedAliasException in inference.
• Model Registry: Fix an issue that signature inference could be incorrect when using Snowpark DataFrame as sample input.
• Model Registry: Fix too strict data type validation when predicting. Now, for example, if you have a INT8
  type feature in the signature, if providing a INT64 dataframe but all values are within the range, it would not fail.

[1.0.9]

Behavior Changes

• Model Development: log_loss metric calculation is now distributed.

Bug Fixes

• Model Registry: Fix an issue that building images fails with specific docker setup.
• Model Registry: Fix an issue that unable to embed local ML library when the library is imported by zipimport.

• Model Registry: Fix an issue that incorrect docker executable is used when building images.

• Model Registry: add create_if_not_exists parameter in constructor.
• Model Registry: Added get_or_create_model_registry API.
• Model Registry: Added support for using GPU inference when deploying XGBoost (xgboost.XGBModel and xgboost.Booster), PyTorch (torch.nn.Module and torch.jit.ScriptModule) and TensorFlow (tensorflow.Module and tensorflow.keras.Model) models to Snowpark Container Services.
• Model Registry: When inferring model signature, Sequence of built-in types, Sequence of numpy.ndarray, Sequence of torch.Tensor, Sequence of tensorflow.Tensor and Sequence of tensorflow.Tensor can be used instead of only List of them.
• Model Registry: Added get_training_dataset API.
• Model Development: Size of metrics result can exceed previous 8MB limit.
• Model Registry: Added support save/load/deploy HuggingFace pipeline object (transformers.Pipeline) and our wrapper (snowflake.ml.model.models.huggingface_pipeline.HuggingFacePipelineModel) to it. Using the wrapper to specify configurations and the model for the pipeline will be loaded dynamically when deploying. Currently, following tasks are supported to log without manually specifying model signatures:
  • "conversational"
  • "fill-mask"
  • "question-answering"
  • "summarization"
  • "table-question-answering"
  • "text2text-generation"
  • "text-classification" (alias "sentiment-analysis" available)
  • "text-generation"
  • "token-classification" (alias "ner" available)
  • "translation"
  • "translation_xx_to_yy"
  • "zero-shot-classification"

Bug Fixes

• Model Development: Fixed a bug when using simple imputer with numpy >= 1.25.
• Model Development: Fixed a bug when inferring the type of label columns.

Behavior Changes

• Model Registry: log_model() now return a ModelReference object instead of a model ID.
• Model Registry: When deploying a model with 1 target method only, the target_method argument can be omitted.
• Model Registry: When using the snowflake-ml-python with version newer than what is available in Snowflake Anaconda Channel, embed_local_ml_library option will be set as True automatically if not.
• Model Registry: When deploying a model to Snowpark Container Services and using GPU, the default value of num_workers will be 1.
• Model Registry: keep_order and output_with_input_features in the deploy options have been removed. Now the behavior is controlled by the type of the input when calling model.predict(). If the input is a pandas.DataFrame, the behavior will be the same as keep_order=True and output_with_input_features=False before. If the input is a snowpark.DataFrame, the behavior will be the same as keep_order=False and output_with_input_features=True before.
• Model Registry: When logging and deploying PyTorch (torch.nn.Module and torch.jit.ScriptModule) and TensorFlow (tensorflow.Module and tensorflow.keras.Model) models, we no longer accept models whose input is a list of tensor and output is a list of tensors. Instead, now we accept models whose input is 1 or more tensors as positional arguments, and output is a tensor or a tuple of tensors. The input and output dataframe when predicting keep the same as before, that is every column is an array feature and contains a tensor.
