Supported Tasks
Happy Transformer supports a broad spectrum of NLP tasks, both for inference and training:
- Text Generation: Create and understand sequences of human-like text.
- Text Classification: Categorize text into predefined classes, useful for sentiment analysis and more.
- Word Prediction: Predict missing words in a sentence using contextual clues.
- Question Answering: Derive answers from given text based on questions posed.
- Text-to-Text Tasks: Perform transformations from one text format to another.
- Next Sentence Prediction: Infer whether a specified sentence logically follows another sentence, available for inference.
- Token Classification: Identify and classify individual entities or token spans within a text.
Getting Started
Installation of Happy Transformer is straightforward. Simply execute the following command to install via pip:
pip install happytransformer
Here is an example of how to use Happy Transformer for word prediction:
from happytransformer import HappyWordPrediction
happy_wp = HappyWordPrediction() # Default uses distilbert-base-uncased
result = happy_wp.predict_mask("I think therefore I [MASK]")
print(result) # [WordPredictionResult(token='am', score=0.10172799974679947)]
print(result[0].token) # am
