[CodeParrot](https://huggingface.co/lvwerra/codeparrot) is a code generation model trained on **50GB** of pre-processed Python data 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
  - Alphanumeric characters fraction > 0.25
  - Remove auto-generated files (keyword search)
