Quickly train and evaluate transformer models with just 3 lines of code.
Train and evaluate transformer models quickly with minimal code.
Simple Transformers is a Python library built on top of Hugging Face Transformers that simplifies training and evaluating NLP models. It allows you to initialize, train, and evaluate a model in just three lines of code, making it ideal for data scientists working with text classification, NER, and question answering.
The library provides task-specific wrapper classes like ClassificationModel, NERModel, and QuestionAnsweringModel to handle datasets easily using Pandas DataFrames. It supports a wide range of tasks including conversational AI, language generation, document retrieval, and multi-modal classification.
It suits data scientists and machine learning engineers who want to prototype and train transformer models quickly without writing boilerplate PyTorch training loops. It does not suit those who need low-level architectural control over every single layer of the transformer without using the library's abstraction layers.
Initialize, train, and evaluate models using only three lines of Python code.
Built-in classes for text classification, NER, question answering, T5, and retrieval.
Feed training and evaluation data directly into models using standard pandas DataFrames.
Optional integration with wandb for tracking and visualizing training experiments.
The software is free under its Apache-2.0 license, and the only cost is running your own hardware infrastructure or optional tracking services like Weights and Biases.
