# InCoder 1B
A 1B parameter decoder-only Transformer model trained on code using a causal-masked objective, which allows inserting/infilling code as well as standard left-to-right generation.
The model was trained on public open-source repositories with a permissive, non-copyleft, license (Apache 2.0, MIT, BSD-2 or BSD-3) from GitHub and GitLab, as well as StackOverflow. Repositories primarily contained Python and JavaScript, but also include code from 28 languages, as well as StackOverflow.
For more information, see our:
- [Demo](https://huggingface.co/spaces/facebook/incoder-demo)
- [Project site](https://sites.google.com/view/incoder-code-models)
- [Examples](https://sites.google.com/view/incoder-code-models/home/examples)
- [Paper](https://arxiv.org/abs/2204.05999)
A larger, 6B, parameter model is also available at [facebook/incoder-6B](https://huggingface.co/facebook/incoder-6B).
## Requirements
`pytorch`, `tokenizers`, and `transformers`. Our model requires HF's tokenizers >= 0.12.1, due to changes in the pretokenizer.
```
pip install torch
pip install "tokenizers>=0.12.1"
pip install transformers
```
## Usage
See [https://github.com/dpfried/incoder](https://github.com/dpfried/incoder) for example code.
### Model
Load with
`model = AutoModelForCausalLM.from_pretrained("facebook/incoder-1B")`
### Tokenizer
`tokenizer = AutoTokenizer.from_pretrained("facebook/incoder-1B")`.
Note: the incoder-1B and incoder-6B tokenizers are identical, so 'facebook/incoder-6B' could also be used.
When calling `tokenizer.decode`, it's important to pass `clean_up_tokenization_spaces=False` to avoid removing spaces after punctuation:
`tokenizer.decode(tokenizer.encode("from ."), clean_up_tokenization_spaces=False)`
