longformer-embedder 0.1.2

A small wrapper for generating Longformer embeddings.

Longformer Embedder

A lightweight wrapper around Hugging Face Longformer to easily generate mean-pooled embeddings.

Installation

pip install longformer-embedder

Usage

from longformer_embedder import LongformerEmbedder

embedder = LongformerEmbedder(model_name="allenai/longformer-base-4096")
vec = embedder.get_embedding("This is a test sentence.")
print(vec.shape)  # (768,)

Batch Mode

texts = ["Text one", "Text two", "Text three"]
embeddings = embedder.generate_embeddings(texts)
print(embeddings.shape)  # (3, 768)

Notes

• Model weights are downloaded from Hugging Face automatically.
• Ensure torch is installed and compatible with your device (CPU/GPU).
• For GPU acceleration, install CUDA-enabled PyTorch.
