| [CodeParrot](https://huggingface.co/lvwerra/codeparrot) was trained on **50GB** of Python data, after preprocessing, from Github repositories: [CodeParrot dataset](https://huggingface.co/datasets/lvwerra/codeparrot-clean). The original dataset contains a lot of duplicated and noisy data. Therefore, the dataset was cleaned with the following steps: | |
| - Exact match deduplication | |
| - Filtering: | |
| - Average line length < 100 tokens | |
| - Maximum line length < 1000 MB | |
| - Alpha numeric characters fraction > 0.25 | |
| - Remove auto-generated files (keyword search) | |
