# What does this model do? |
|
This model converts the natural language input to Neo4j (Cypher) 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. More information can be found on the repository. |

|
```python |
|
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM |

model = AutoModelForSeq2SeqLM.from_pretrained("Chirayu/nl2cql") |
|
tokenizer = AutoTokenizer.from_pretrained("Chirayu/nl2cql") |
|
device = torch.device("cuda" if torch.cuda.is_available() else "cpu") |
|
model = model.to(device) |
