spacy-transformers: Use pretrained transformers like BERT, XLNet and GPT-2 in spaCy
This package provides spaCy components and
architectures to use transformer models via
spaCy. The result is convenient access to state-of-the-art transformer
architectures, such as BERT, GPT-2, XLNet, etc.
- Use pretrained transformer models like BERT, RoBERTa and XLNet to power your spaCy pipeline.
- Easy multi-task learning: backprop to one transformer model from several pipeline components.
- Train using spaCy v3's powerful and extensible config system.
- Automatic alignment of transformer output to spaCy's tokenization.
- Easily customize what transformer data is saved in the
- Easily customize how long documents are processed.
- Out-of-the-box serialization and model packaging.
Installing the package from pip will automatically install all dependencies, including PyTorch and spaCy. Make sure you install this package before you install the models. Also note that this package requires Python 3.6+, PyTorch v1.5+ and spaCy v3.0+.
pip install spacy[transformers]
For GPU installation, find your CUDA version using
nvcc --version and add the
version in brackets, e.g.
spacy[transformers,cuda92] for CUDA9.2 or
If you are having trouble installing PyTorch, follow the instructions on the official website for your specific operating system and requirements, or try the following:
pip install spacy-transformers -f https://download.pytorch.org/whl/torch_stable.html
⚠️ Important note: This package has been extensively refactored to take advantage of spaCy v3.0. Previous versions that were built for spaCy v2.x worked considerably differently. Please see previous tagged versions of this README for documentation on prior versions.
