# sentence-transformers/gtr-t5-xl
|
13 |
-
|
14 |
-
This is a [sentence-transformers](https://www.SBERT.net) model: It maps sentences & paragraphs to a 768 dimensional dense vector space. The model was specifically trained for the task of sematic search.
|
15 |
-
|
16 |
-
This model was converted from the Tensorflow model [gtr-xl-1](https://tfhub.dev/google/gtr/gtr-xl/1) to PyTorch. When using this model, have a look at the publication: [Large Dual Encoders Are Generalizable Retrievers](https://arxiv.org/abs/2112.07899). The tfhub model and this PyTorch model can produce slightly different embeddings, however, when run on the same benchmarks, they produce identical results.
|
17 |
-
|
18 |
-
The model uses only the encoder from a T5-3B model. The weights are stored in FP16.

## Usage (Sentence-Transformers)
|
22 |
-
|
23 |
-
Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:
|
24 |
-
|
25 |
-
```
|
26 |
-
pip install -U sentence-transformers
|
27 |
-
```
|
28 |
-
|
29 |
-
Then you can use the model like this:
|
30 |
-
|
31 |
-
```python
|
32 |
-
from sentence_transformers import SentenceTransformer
|
33 |
-
sentences = ["This is an example sentence", "Each sentence is converted"]
|
34 |
-
|
35 |
-
model = SentenceTransformer('sentence-transformers/gtr-t5-xl')
|
36 |
-
embeddings = model.encode(sentences)
|
37 |
-
print(embeddings)
|
38 |
-
```
