BERT (Bidirectional Encoder Representations from Transformers) is a deep learning technique for natural language processing (NLP). This tutorial will guide you through the process of implementing BERT in Python.

Prerequisites

  • Basic understanding of Python programming
  • Familiarity with NLP concepts
  • TensorFlow or PyTorch framework

Installation

First, you need to install the necessary libraries. You can do this by running the following commands:

pip install transformers
pip install tensorflow  # or pip install torch

Step-by-Step Implementation

1. Import Libraries

import transformers
from transformers import BertTokenizer, BertModel

2. Load the Model and Tokenizer

tokenizer = BertTokenizer.from_pretrained('bert-base-uncased')
model = BertModel.from_pretrained('bert-base-uncased')

3. Preprocess the Text

text = "This is a sample text for BERT implementation."
encoded_input = tokenizer(text, return_tensors='pt')

4. Forward Pass

output = model(**encoded_input)

5. Extracting Features

last_hidden_state = output.last_hidden_state
