Thinc

✨ New features and improvements

To improve loading times and reduce conflicts, MXNet and TensorFlow are no longer imported automatically (890).

⚠️ Backwards incompatibilities

MXNet and TensorFlow support needs to be enabled explicitly. Previously, MXNet and TensorFlow were imported automatically if they were available in the current environment.

To enable MXNet:

python
from thinc.api import enable_mxnet
enable_mxnet()


To enable TensorFlow:

python
from thinc.api import enable_tensorflow
enable_tensorflow()


With spaCy CLI commands you can provide this custom code using `-c code.py`. For training use `spacy train -c code.py` and to package your code with your pipeline use `spacy package -c code.py`.

Future deprecation warning: built-in MXNet and TensorFlow support will be removed in Thinc v9. If you need MXNet or TensorFlow support in the future, you can transition to using a custom copy of the current `MXNetWrapper` or `TensorFlowWrapper` in your package or project.
