Model Summary

SantaCoderPack is an pre-trained model with the same architecture of SantaCoder on CommitPack using this format:

<commit_before>code_before<commit_msg>message<commit_after>code_after
Data CommitPack 4TB of GitHub commits across 350 programming languages
Model SantaCoderPack SantaCoderPack (1.1B parameters) pre-trained on CommitPack
Evaluation   HumanEvalPack/HumanEvalFix Extension of OpenAI's HumanEval to HumanEvalFix

Use

Intended use

The model follows instructions provided in the input. We recommend prefacing your input with "def has_close_elements(numbers: List[float], threshold: float) -> bool:\n for idx, elem in enumerate(numbers):\n for idx2, elem2 in enumerate(numbers):\n if idx != idx2:\n distance = elem - elem2\n if distance < threshold:\n return True\n\n return FalseFix bugs in has_close_elements."

Feel free to share your generations in the Community tab!

Generation

# pip install -q transformers
from transformers import AutoModelForCausalLM, AutoTokenizer
checkpoint = "bigcode/santacoderpack"
device = "cuda" # for GPU usage or "cpu" for CPU usage
tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(checkpoint).to(device)
inputs = tokenizer.encode("Q<commit_before>def has_close_elements(numbers: List[float], threshold: float) -> bool:\n    for idx, elem in enumerate(numbers):\n        for idx2, elem2 in enumerate(numbers):\n            if idx != idx2:\n                distance = elem - elem2\n                if distance < threshold:\n                    return True\n\n    return False<commit_message>Fix bugs in has_close_elements.<commit_after>", return_tensors="pt").to(device)
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))
