Fine-tune BERT (examples are given for single-sentence and multi-sentence datasets) Save the trained model and use it Key Point: The model you develop will be end-to-end. In addition to reading this blog, check out the demo discussed in more detail below, showing how you can use TensorFlow 2.0 in Azure to fine-tune a BERT (Bidirectional Encoder Representations from Transformers) model for automatically tagging questions. Then, we will search for tuning the hyperparameters. pip install -q tf-models-official==2.7. BERT Tokenizer 3.2. To fine-tune BERT, you really only need intermediate fluency with Python, and experience manipulating arrays and tensors correctly. 1.3 Feed the pre-trained vector representations into a model for a downstream task (such as text classification). It is trained on Wikipedia and the Book Corpus dataset. BERT is a pre-trained Transformer Encoder stack. That was the uncased model while we are currently using the cased model, which explains the better result. So my doubt is if I set this to false does it mean that I am freezing all the layers of the BERT which is my intension too. I have tried to follow the tutorial from the tensorflow website.
