Project description
Fast Sentence Transformers
This repository contains code to run faster sentence-transformers using tools like quantization and ONNX. Just run your model much faster, while a lot of memory. There is not much to it!
Quickstart
from fast_sentence_transformers import FastSentenceTransformer as SentenceTransformer
# use any sentence-transformer
encoder = SentenceTransformer("all-MiniLM-L6-v2", device="cpu", quantize=True)
encoder.encode("Hello hello, hey, hello hello")
encoder.encode(["Life is too short to eat bad food!"] * 2)
Benchmark
Indicative benchmark for CPU usage with smallest and largest model on sentence-transformers. Note, ONNX doesn't have GPU support for quantization yet.
| model | Type | default | ONNX | ONNX+quantized | ONNX+GPU |
|---|---|---|---|---|---|
| paraphrase-albert-small-v2 | memory | 1x | 1x | 1x | 1x |
| speed | 1x | 2x | 5x | 20x | |
| paraphrase-multilingual-mpnet-base-v2 | memory | 1x | 1x | 4x | 4x |
| speed | 1x | 2x | 5x | 20x |
Shout-Out
This package heavily leans on sentence-transformers and txtai.
