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
