+
|
10 |
+
## Introduction
|
11 |
+
|
12 |
+
BertChunker is an end-to-end trained chunker for chunking text for RAG. It's trained based on [MiniLM-L6-H384-uncased](https://huggingface.co/nreimers/MiniLM-L6-H384-uncased) with an adapter.
|
13 |
+
|
14 |
+
This repo includes model checkpoint, BertChunker class definition file and all the other files needed.
|
15 |
+
|
16 |
+
## Quickstart
|
17 |
+
Download this repository. Then enter it. Run the following:
|

+
|
19 |
+
```python
|
20 |
+
import safetensors
|
21 |
+
from transformers import AutoConfig,AutoTokenizer
|
22 |
+
from modeling_bertchunker import BertChunker
|
23 |
+
|
24 |
+
# load bert tokenizer
|
25 |
+
