# plT5 Large |
|
**plT5** models are T5-based language models trained on Polish corpora. The models were optimized for the original T5 denoising target. |
|
|
|
## Corpus |
|
plT5 was trained on six different corpora available for Polish language: |
|
|
|
| Corpus | Tokens | Documents | |
|
| :------ | ------: | ------: | |
|
| [CCNet Middle](https://github.com/facebookresearch/cc_net) | 3243M | 7.9M | |
|
| [CCNet Head](https://github.com/facebookresearch/cc_net) | 2641M | 7.0M | |
|
| [National Corpus of Polish](http://nkjp.pl/index.php?page=14&lang=1)| 1357M | 3.9M | |
|
| [Open Subtitles](http://opus.nlpl.eu/OpenSubtitles-v2018.php) | 1056M | 1.1M |
|
| [Wikipedia](https://dumps.wikimedia.org/) | 260M | 1.4M | |
|
| [Wolne Lektury](https://wolnelektury.pl/) | 41M | 5.5k | |
|
|
|
## Tokenizer |
|
The training dataset was tokenized into subwords using a sentencepiece unigram model with |
|
vocabulary size of 50k tokens. |
|
|
|
## Usage |
|
Example code: |
|
```python |
|
from transformers import AutoTokenizer, AutoModel |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("allegro/plt5-large") |
|
model = AutoModel.from_pretrained("allegro/plt5-large") |
|
``` |
