Simple Transformers

This library is based on the Transformers library by HuggingFace. Simple Transformers lets you quickly train and evaluate Transformer models. Only 3 lines of code are needed to initialize a model, train the model, and evaluate a model.

Supports

  • Sequence Classification
  • Token Classification (NER)
  • Question Answering
  • Language Model Fine-Tuning
  • Language Model Training
  • Language Generation
  • T5 Model
  • Seq2Seq Tasks
  • Multi-Modal Classification
  • Conversational AI.
  • Text Representation Generation.

Setup

With Conda

  1. Install Anaconda or Miniconda Package Manager from here

  2. Create a new virtual environment and install packages. conda create -n st python pandas tqdm conda activate st If using cuda:     conda install pytorch>=1.6 cudatoolkit=10.2 -c pytorch else:     conda install pytorch cpuonly -c pytorch

  3. Install simpletransformers. pip install simpletransformers

Optional

  1. Install Weights and Biases (wandb) for tracking and visualizing training in a web browser. pip install wandb

Usage

All documentation is now live at simpletransformers.ai

Simple Transformer models are built with a particular Natural Language Processing (NLP) task in mind. Each such model comes equipped with features and functionality designed to best fit the task that they are intended to perform. The high-level process of using Simple Transformers models follows the same pattern.

  1. Initialize a task-specific model
  2. Train the model with train_model()
  3. Evaluate the model with eval_model()
  4. Make predictions on (unlabelled) data with predict()

However, there are necessary differences between the different models to ensure that they are well suited for their intended task. The key differences will typically be the differences in input/output data formats and any task specific features/configuration options. These can all be found in the documentation section for each task.

The currently implemented task-specific Simple Transformer models, along with their task, are given below.

Task Model
Binary and multi-class text classification ClassificationModel
Conversational AI (chatbot training) ConvAIModel
Language generation LanguageGenerationModel
Language model training/fine-tuning LanguageModelingModel
Multi-label text classification MultiLabelClassificationModel
Multi-modal classification (text and image data combined) MultiModalClassificationModel
Named entity recognition NERModel
Question answering QuestionAnsweringModel
Regression ClassificationModel
Sentence-pair classification ClassificationModel
Text Representation Generation RepresentationModel
  • Please refer to the relevant section in the docs for more information on how to use these models.

  • Example scripts can be found in the examples directory.

  • See the Changelog for up-to-date changes to the project.

A quick example

from simpletransformers.classification import ClassificationModel, ClassificationArgs
import pandas as pd
import logging


logging.basicConfig(level=logging.INFO)
transformers_logger = logging.getLogger("transformers")
transformers_logger.setLevel(logging.WARNING)

# Preparing train data
train_data = [
    ["Aragorn was the heir of Isildur", 1],
    ["Frodo was the heir of Isildur", 0],
]
train_df = pd.DataFrame(train_data)
train_df.columns = ["text", "labels"]

# Preparing eval data
eval_data = [
    ["Theoden was the king of Rohan", 1],
    ["Merry was the king of Rohan", 0],
]
eval_df = pd.DataFrame(eval_data)
eval_df.columns = ["text", "labels"]

# Optional model configuration
model_args = ClassificationArgs(num_train_epochs=1)

# Create a ClassificationModel
model = ClassificationModel(
    "roberta", "roberta-base", args=model_args
)

# Train the model
model.train_model(train_df)

# Evaluate the model
result, model_outputs, wrong_predictions = model.eval_model(eval_df)

# Make predictions with the model
predictions, raw_outputs = model.predict(["Sam was a Wizard"])

Current Pretrained Models

For a list of pretrained models, see Hugging Face docs.

The model_types available for each task can be found under their respective section. Any pretrained model of that type found in the Hugging Face docs should work. To use any of them set the correct model_type and model_name in the args dictionary.

How to Contribute

How to Update Docs

The latest version of the docs is hosted on Github Pages, if you want to help document Simple Transformers below are the steps to edit the docs. Docs are built using Jekyll library, refer to their webpage for a detailed explanation of how it works.

  1. Install Jekyll: Run the command gem install bundler jekyll
  2. Visualizing the docs on your local computer: In your terminal cd into the docs directory of this repo, eg: cd simpletransformers/docs From the docs directory run this command to serve the Jekyll docs locally: bundle exec jekyll serve Browse to http://localhost:4000 or whatever url you see in the console to visualize the docs.
  3. Edit and visualize changes: All the section pages of our docs can be found under docs/_docs directory, you can edit any file you want by following the markdown format and visualize the changes after refreshing the browser tab.

Acknowledgements

None of this would have been possible without the hard work by the HuggingFace team in developing the Transformers library.
