## Usage (HuggingFace Transformers)
|
40 |
+
Without [sentence-transformers](https://www.SBERT.net), you can use the model like this: First, you pass your input through the transformer model, then you have to apply the right pooling-operation on-top of the contextualized word embeddings.
|
41 |
+
|
42 |
+
```python
|
43 |
+
from transformers import AutoTokenizer, AutoModel
|
44 |
+
import torch
|
45 |
+
|
46 |
+
|

#Mean Pooling - Take attention mask into account for correct averaging
|
48 |
+
def mean_pooling(model_output, attention_mask):
|
49 |
+
token_embeddings = model_output[0] #First element of model_output contains all token embeddings
|
50 |
+
input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
|
51 |
+
return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)
|
