Configuration for MaskedLanguageModel

Contains information regarding the model to load and device to place the model on.

Fields

model_type: ModelType

Model type

model_resource: Box<dyn ResourceProvider + Send>

Model weights resource (default: pretrained BERT model on CoNLL)

config_resource: Box<dyn ResourceProvider + Send>

Config resource (default: pretrained BERT model on CoNLL)

vocab_resource: Box<dyn ResourceProvider + Send>

Vocab resource (default: pretrained BERT model on CoNLL)

merges_resource: Option<Box<dyn ResourceProvider + Send>>

Merges resource (default: None)

lower_case: bool

Automatically lower case all input upon tokenization (assumes a lower-cased model)

strip_accents: Option<bool>

Flag indicating if the tokenizer should strip accents (normalization). Only used for BERT / ALBERT models

add_prefix_space: Option<bool>

Flag indicating if the tokenizer should add a white space before each tokenized input (needed for some Roberta models)

mask_token: Option<String>

Token used for masking words. This is the token which the model will try to predict.

device: Device

Device to place the model on (default: CUDA/GPU when available)

Implementations

impl MaskedLanguageConfig

pub fn new<RM, RC, RV>(
    model_type: ModelType,
    model_resource: RM,
    config_resource: RC,
    vocab_resource: RV,
    merges_resource: Option<RV>,
    lower_case: bool,
    strip_accents: impl Into<Option<bool>>,
    add_prefix_space: impl Into<Option<bool>>,
    mask_token: impl Into<Option<String>>
) -> MaskedLanguageConfigwhere
    RM: ResourceProvider + Send + 'static,
    RC: ResourceProvider + Send + 'static,
    RV: ResourceProvider + Send + 'static,

Instantiate a new masked language configuration of the supplied type.

Arguments

• model_type - ModelType indicating the model type to load (must match with the actual data to be loaded!)
• model_resource - The ResourceProvider pointing to the model to load (e.g. model.ot)
• config - The ResourceProvider pointing to the model configuration to load (e.g. config.json)
• vocab - The ResourceProvider pointing to the tokenizer’s vocabulary to load (e.g. vocab.txt/vocab.json)
• vocab - An optional ResourceProvider pointing to the tokenizer’s merge file to load (e.g. merges.txt), needed only for Roberta.
• lower_case - A bool indicating whether the tokenizer should lower case all input (in case of a lower-cased model)
• mask_token - A token used for model to predict masking words..
