# 🤗 + 📚 dbmdz Turkish BERT model |
|
|
|
In this repository the MDZ Digital Library team (dbmdz) at the Bavarian State |
|
Library open sources a cased model for Turkish 🎉 |
|
|
|
# 🇹🇷 BERTurk |
|
|
|
BERTurk is a community-driven cased BERT model for Turkish. |
|
|
|
Some datasets used for pretraining and evaluation are contributed from the |
|
awesome Turkish NLP community, as well as the decision for the model name: BERTurk. |
|
|
|
## Stats |
|
|
|
The current version of the model is trained on a filtered and sentence |
|
segmented version of the Turkish [OSCAR corpus](https://traces1.inria.fr/oscar/), |
|
a recent Wikipedia dump, various [OPUS corpora](http://opus.nlpl.eu/) and a |
|
special corpus provided by [Kemal Oflazer](http://www.andrew.cmu.edu/user/ko/). |
|
|
|
The final training corpus has a size of 35GB and 44,04,976,662 tokens. |
|
|
|
Thanks to Google's TensorFlow Research Cloud (TFRC) we could train a cased model |
|
on a TPU v3-8 for 2M steps. |
|
|
|
For this model we use a vocab size of 128k. |
|
|
|
## Model weights |
|
|
|
Currently only PyTorch-[Transformers](https://github.com/huggingface/transformers) |
|
compatible weights are available. If you need access to TensorFlow checkpoints, |
|
please raise an issue! |

|
## Usage |
|
|
|
With Transformers >= 2.3 our BERTurk cased model can be loaded like: |
|
|
|
```python |
|
from transformers import AutoModel, AutoTokenizer |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("dbmdz/bert-base-turkish-128k-cased") |
|
model = AutoModel.from_pretrained("dbmdz/bert-base-turkish-128k-cased") |
|
``` |
|
|
