In today’s rapidly evolving AI landscape, text embeddings are crucial for various tasks such as classification, retrieval, clustering, and semantic search. This guide will walk you through how to utilize the FlagEmbedding library to map your text to dense vector representations effectively. We’ll also provide troubleshooting tips to ensure your experience is smooth.
Getting Started with FlagEmbedding
- Installation: You can easily install FlagEmbedding with pip. Open your terminal and run:
pip install -U FlagEmbedding
Usage for Embedding Model
Here’s a simple example of how to encode sentences into embeddings using FlagEmbedding:
from FlagEmbedding import FlagModel
sentences_1 = ["Sample data 1", "Sample data 2"]
sentences_2 = ["Sample data 3", "Sample data 4"]
model = FlagModel("BAAIbge-large-zh-v1.5", query_instruction_for_retrieval="Generate vector representation for relevant articles:", use_fp16=True)
embeddings_1 = model.encode(sentences_1)
embeddings_2 = model.encode(sentences_2)
similarity = embeddings_1 @ embeddings_2.T
print(similarity)
In this example, we initialize the model and encode two groups of sentences, obtaining their embeddings. The similarity score between these embeddings reveals how closely related the sentences are.
Troubleshooting Common Issues
If you encounter any problems while using FlagEmbedding, consider the following troubleshooting steps:
- Issue: The encoding process is slow.
- Solution: Ensure that you set
use_fp16=Trueto speed up computation. - Issue: You receive inaccurate similarity scores.
- Solution: Use the new version [BAAIbge-base-en-v1.5](https://huggingface.co/BAAIbge-base-en-v1.5) for better similarity distribution.
- Issue: Queries yield unexpected results.
- Solution: It is recommended to add query instructions for retrieval tasks, ensuring that context is maintained.
