Now you have access to many transformer-based models including the pre-trained Bert models in pytorch. First you install the amazing transformers package by huggingface with. I will show you how you can finetune the Bert model to do state-of-the art named entity recognition. Installation pip install pytorch-text-crf Usage This code is based on the excellent Allen NLP implementation of CRF.
This package contains a simple wrapper for using conditional random fields(CRF). The forward computation of this class computes the log likelihood of the given sequence of tags and emission score tensor. This module implements a conditional random field _.
