paraphrase-multilingual-mpnet-base-v2-embedding-all

This model is a fine-tuned version of paraphrase-multilingual-mpnet-base-v2 on the following datasets: squad, newsqa, LLukas22/cqadupstack, LLukas22/fiqa, LLukas22/scidocs, deepset/germanquad, LLukas22/nq.

Usage (Sentence-Transformers)

Using this model becomes easy when you have sentence-transformers installed:

pip install -U sentence-transformers

Then you can use the model like this:

python

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('LLukas22/paraphrase-multilingual-mpnet-base-v2-embedding-all')
embeddings = model.encode(sentences)
print(embeddings)
