text-embedding
Text Embedding with Transformers
author: Jael Gu
Description
A text embedding operator takes a sentence, paragraph, or document in string as an input and output an embedding vector in ndarray which captures the input's core semantic elements. This operator is implemented with pre-trained models from Huggingface Transformers.
Code Example
Use the pre-trained model 'distilbert-base-cased' to generate a text embedding for the sentence "Hello, world.".
Write the pipeline:
import towhee
(
towhee.dc(["Hello, world."])
.text_embedding.transformers(model_name="distilbert-base-cased")
)
Write a same pipeline with explicit inputs/outputs name specifications:
import towhee
(
towhee.dc['text'](["Hello, world."])
.text_embedding.transformers['text', 'vec'](model_name="distilbert-base-cased")
.show()
)
Factory Constructor
Create the operator via the following factory method:
text_embedding.transformers(model_name="bert-base-uncased")
Parameters:
model_name: str
The model name in string. The default model name is "bert-base-uncased".
Supported model names:

Interface
The operator takes a piece of text in string as input. It loads tokenizer and pre-trained model using model name. and then return text embedding in ndarray.
call(txt)
Parameters:
txt: str
The text in string.
Returns:
numpy.ndarray
The text embedding extracted by model.
save_model(format='pytorch', path='default')
Save model to local with specified format.
Parameters:
format: str
The format of saved model, defaults to 'pytorch'.
format: path
The path where model is saved to. By default, it will save model to the operator directory.
supported_model_names(format=None)
Get a list of all supported model names or supported model names for specified model format.
Parameters:
format: str
The model format such as 'pytorch', 'torchscript'.
