How to Use Pretrained Transformers in spaCy

Unlock the power of your text processing tasks with pretrained transformers such as BERT, RoBERTa, and XLNet using the spaCy-transformers package. This user-friendly guide will walk you through the installation and application of transformer models in your spaCy pipeline.

Getting Started with spaCy-transformers

The spaCy-transformers package gives you access to state-of-the-art transformer architectures through Hugging Face’s transformers. However, to get started, you need to ensure you have the right prerequisites:

• Python 3.6+
• PyTorch v1.5+
• spaCy v3.0+

Installation

To install the package, you can use pip, which will take care of installing all necessary dependencies:

pip install spacy[transformers]

GPU Installation

If you want faster processing with GPU support, find your CUDA version using:

nvcc --version

Then add the relevant version in brackets. For example:

pip install spacy[transformers,cuda92]

Understanding Transformers in spaCy

Imagine you have a powerful Swiss Army knife (the transformer). Just like how a Swiss Army knife has multiple tools for different tasks, a transformer model can provide various functionalities for handling language. When integrated with spaCy, you can utilize these functionalities in a structured way. For instance, if you have several tools (pipeline components) that need to work together (multi-task learning), you can orchestrate them to achieve an effective outcome, just like different tools in a Swiss Army knife functioning seamlessly to complete a project.

Key Features

The spaCy-transformers package comes loaded with features:

• Use pretrained transformer models like BERT and XLNet in your pipeline.
• Automatic alignment of transformer output with spaCy’s tokenization.
• Effortless multi-task learning.
• Easy customization of how data is processed and saved.
• Out-of-the-box model packaging.

Documentation and Learning Resources

If you need further guidance, the documentation provides several resources:

• Embeddings, Transformers and Transfer Learning
• Training Pipelines and Models
• Layers and Model Architectures
• Transformer Pipeline Component API Reference
• Transformer Architectures

Troubleshooting Common Issues

If you encounter issues during installation or usage, consider the following troubleshooting steps:

• Ensure you have the required versions of Python, spaCy, and PyTorch.
• Check the CUDA version compatibility if you are installing with GPU.
• Review the [spaCy issue tracker](https://github.com/explosion/spaCy/issues) to see if your issue has already been discussed.
