We have extended support for the SentencePiece tokenizer, which traditionally uses a protobuf data file (tokenizer.model). This update introduces the ability to create a tokenizer object by passing an options object containing tokenizer data such as vocabulary and normalization. With this change, users can initialize a tokenizer without loading a protobuf file, enabling them to source tokenizer data from formats like JSON files and other alternatives.

We have extended support for the SentencePiece tokenizer, which traditionally uses a protobuf data file (tokenizer.model). This update introduces the ability to create a tokenizer object by passing an options object containing tokenizer data such as vocabulary and normalization. With this change, users can initialize a tokenizer without loading a protobuf file, enabling them to source tokenizer data from formats like JSON files and other alternatives.

PR Overview

This PR introduces the ability to create a SentencePieceTokenizer from an options object, enabling support for models defined by JSON or similar non-protobuf formats. Key changes include adding a new SentencePieceOptions class with configurable properties, updating existing model implementations and tests to support options-based creation, and adding new constructors and methods to handle JSON-based initialization.

We have extended support for the SentencePiece tokenizer, which traditionally uses a protobuf data file (tokenizer.model). This update introduces the ability to create a tokenizer object by passing an options object containing tokenizer data such as vocabulary and normalization. With this change, users can initialize a tokenizer without loading a protobuf file, enabling them to source tokenizer data from formats like JSON files and other alternatives.

PR Overview

This PR introduces the ability to create a SentencePieceTokenizer from an options object, enabling support for models defined by JSON or similar non-protobuf formats. Key changes include adding a new SentencePieceOptions class with configurable properties, updating existing model implementations and tests to support options-based creation, and adding new constructors and methods to handle JSON-based initialization.

Reviewed Changes

FileDescription
src/Microsoft.ML.Tokenizers/Model/SentencePieceOptions.csAdds a new options class to configure SentencePiece model properties.
test/Microsoft.ML.Tokenizers.Tests/UnigramTests.csIntroduces tests ensuring the created tokenizer from JSON behaves as expected and validates shifted token IDs.
src/Microsoft.ML.Tokenizers/Model/SentencePieceUnigramModel.csUpdates constructor and internal methods to support options-based initialization and renames internal counter for normalized text.
src/Microsoft.ML.Tokenizers/Model/SentencePieceBpeModel.csAdds a new constructor that validates unsupported normalization data and initializes the vocabulary based on options.
src/Microsoft.ML.Tokenizers/Model/SentencePieceBaseModel.csIntroduces a new constructor from options and changes token ID properties from read-only to mutable.
src/Microsoft.ML.Tokenizers/Model/SentencePieceTokenizer.csAdds an overload of the Create method that instantiates a tokenizer using the options object.
