fasttext.rs
A Rust-backed Python implementation of Facebook's fastText.
Installation
uv add fasttext-rs
# or
uv pip install fasttext-rs
Quick start
import fasttext_rs
# Train
model = fasttext_rs.train_supervised(input="cooking.train", epoch=25, lr=1.0, word_ngrams=2)
# Predict
labels, probs = model.predict("Which baking dish is best?")
# Vectors
vec = model.get_word_vector("hello")
# Save / Load
model.save_model("model.bin")
model = fasttext_rs.load_model("model.bin")
Performance
Benchmarked on the cooking.stackexchange dataset (12k training, 3k validation) with default parameters, single-threaded. Median of 5 runs, Apple M3 Pro.
