# turkish-base-bert-uncased

This is a Turkish Base uncased BERT model. Since this model is uncased: it does not make a difference between turkish and Turkish. 

#### ⚠ Uncased use requires manual lowercase conversion

 
**Don't** use the `do_lower_case = True` flag with the tokenizer. Instead, convert your text to lower case as follows: 
```python
text.replace("I", "ı").lower()
```
This is due to a [known issue](https://github.com/huggingface/transformers/issues/6680) with the tokenizer.

Be aware that this model may exhibit biased predictions as it was trained primarily on crawled data, which inherently can contain various biases.

Other relevant information can be found in the [paper](https://arxiv.org/abs/2307.14134). 


## Example Usage
```python
from transformers import AutoTokenizer, BertForMaskedLM
from transformers import pipeline

model = BertForMaskedLM.from_pretrained("ytu-ce-cosmos/turkish-base-bert-uncased")
# or
# model = BertForMaskedLM.from_pretrained("ytu-ce-cosmos/turkish-base-bert-uncased", from_tf = True)

tokenizer = AutoTokenizer.from_pretrained("ytu-ce-cosmos/turkish-base-bert-uncased")

unmasker = pipeline('fill-mask', model=model, tokenizer=tokenizer)
unmasker("gelirken bir litre [MASK] aldım.")
[{'score': 0.6248273253440857,
  'token': 2417,
  'token_str': 'su',
  'sequence': 'gelirken bir litre su aldım.'},
