# Data Portrait: StarCoder training data

A [Data Portrait](https://github.com/ruyimarone/data-portraits) of [bigcode/starcoderdata](https://huggingface.co/datasets/bigcode/starcoderdata) (The Stack v1.2 in 86 languages,
GitHub issues, Jupyter notebooks and git commits), the training data of [bigcode/starcoderbase](https://huggingface.co/bigcode/starcoderbase) (and its 1B/3B/7B versions) and
[bigcode/starcoder](https://huggingface.co/bigcode/starcoder). StarCoder is StarCoderBase
further trained on the Python subset, so this portrait covers both. StarCoder's special tokens (`<reponame>`,
`<gh_stars>`, `<issue_comment>`, `<jupyter_code>`, ...) inside the stored text are replaced by newlines.

Text is normalised as in data-portraits and split into 50-character n-grams with stride
50, stored in 1 Bloom filter(s) sized to fit in RAM. A query ORs membership
across filters: combined false-positive rate <= 0.01 (each filter 0.010000).

Each partition is a separate revision of this repo (tag `p<i>of<k>`, branch `partition-<n>`):

`partitions.json` lists the exact files (pinned dataset revision) in each partition. Query with
`portraits.query`:

```python
from portraits.query import SequentialPortrait
portrait = SequentialPortrait("aalkaswan/starcoder-portrait", ["p0of1"])
report = portrait.contains_from_text([text], sort_chains_by_length=True)[0]
```
