What does this model do?

This model converts the natural language input to MongoDB (MQL) query. It is a fine-tuned CodeT5+ 220M. This model is a part of nl2query repository which is present at https://github.com/Chirayu-Tripathi/nl2query

You can use this model via the github repository or via following code.

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
import torch
model = AutoModelForSeq2SeqLM.from_pretrained("Chirayu/nl2mongo")
tokenizer = AutoTokenizer.from_pretrained("Chirayu/nl2mongo")
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = model.to(device)
