| # fim-dataset |
|
|
| A Fill-in-the-Middle (FIM) dataset for code autocompletion. |
|
|
| ## Dataset Description |
|
|
| This dataset is designed for training code autocompletion models using the Fill-in-the-Middle (FIM) approach. |
| The dataset contains code snippets formatted with FIM special tokens: |
| - `<fim_prefix>`: Code before the completion point |
| - `<fim_suffix>`: Code after the completion point |
| - `<fim_middle>`: The code to be completed |
|
|
| ## Dataset Structure |
|
|
| ### Data Fields |
|
|
| - `text`: The formatted FIM instruction containing prefix, suffix, and middle tokens |
|
|
| ### Data Splits |
|
|
| | Split | Examples | |
| |-------|----------| |
| | train | 42,922 | |
| | validation | 2,259 | |
|
|
| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| # Load the dataset |
| dataset = load_dataset("KrzTyb/fim-dataset") |
| |
| # Access train and validation splits |
| train_data = dataset["train"] |
| val_data = dataset["validation"] |
| |
| # Example: Print first training example |
| print(train_data[0]["text"]) |
| ``` |
|
|
| ## Training |
|
|
| This dataset can be used to fine-tune code language models for autocompletion: |
|
|
| ```python |
| from transformers import AutoModelForCausalLM, AutoTokenizer, Trainer |
| from datasets import load_dataset |
| |
| # Load model and tokenizer |
| model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen2.5-Coder-0.5B") |
| tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-Coder-0.5B") |
| |
| # Add FIM tokens |
| fim_tokens = ["<fim_prefix>", "<fim_suffix>", "<fim_middle>", "<fim_pad>"] |
| tokenizer.add_special_tokens({"additional_special_tokens": fim_tokens}) |
| model.resize_token_embeddings(len(tokenizer)) |
| |
| # Load dataset |
| dataset = load_dataset("KrzTyb/fim-dataset") |
| |
| # Train (see full training script for details) |
| trainer = Trainer( |
| model=model, |
| train_dataset=dataset["train"], |
| eval_dataset=dataset["validation"], |
| # ... other training arguments |
| ) |
| trainer.train() |
| ``` |
