在Jupyter或Colab环境中,通过以下命令安装BertViz及其依赖项:
pip install bertviz
pip install jupyterlab
pip install ipywidgets
以下是一个简单的代码示例,展示如何使用BertViz可视化BERT模型的注意力:
from bertviz import model_view
from transformers import BertTokenizer, BertModel
model_name = 'bert-base-uncased'
model = BertModel.from_pretrained(model_name, output_attentinotallow=True)
tokenizer = BertTokenizer.from_pretrained(model_name)
text = "The cat sat on the mat."
inputs = tokenizer.encode_plus(text, return_tensors='pt')
outputs = model(**inputs)
attentions = outputs.attentions
tokens = tokenizer.convert_ids_to_tokens(inputs['input_ids'][0])
model_view(attentions, tokens)
