## Stats |
|
|
|
In addition to the recently released [German BERT](https://deepset.ai/german-bert) |
|
model by [deepset](https://deepset.ai/) we provide another German-language model. |
|
|
|
The source data for the model consists of a recent Wikipedia dump, EU Bookshop corpus, |
|
Open Subtitles, CommonCrawl, ParaCrawl and News Crawl. This results in a dataset with |
|
a size of 16GB and 2,350,234,427 tokens. |
|
|
|
For sentence splitting, we use [spacy](https://spacy.io/). Our preprocessing steps |
|
(sentence piece model for vocab generation) follow those used for training |
|
[SciBERT](https://github.com/allenai/scibert). The model is trained with an initial |
|
sequence length of 512 subwords and was performed for 1.5M steps. |
|
|
|
This release includes both cased and uncased models. |
|
|
|
## 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 German BERT models can be loaded like: |
|
|
|
```python |
|
from transformers import AutoModel, AutoTokenizer |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("dbmdz/bert-base-german-cased") |
|
model = AutoModel.from_pretrained("dbmdz/bert-base-german-cased") |
|
``` |
|
|
|
