# Dataset Card for MultiPL-E

## Dataset Description

## Dataset Summary

MultiPL-E is a dataset for evaluating large language models for code
generation that supports 18 programming languages. It takes the OpenAI 
"HumanEval" Python benchmarks and uses little compilers to translate them 
to other languages. It is easy to add support for new languages and benchmarks.

## Example

The following script uses the Salesforce/codegen model to generate Lua
and MultiPL-E to produce a script with unit tests for luaunit.

```python
import datasets
from transformers import AutoTokenizer, AutoModelForCausalLM

LANG = "lua"
MODEL_NAME = "Salesforce/codegen-350M-multi"
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
model = AutoModelForCausalLM.from_pretrained(MODEL_NAME).half().cuda()
problems = datasets.load_dataset("nuprl/MultiPL-E", LANG)

def stop_at_stop_token(decoded_string, problem):
    """
    Truncates the output at stop tokens, taking care to skip the prompt
    which may have stop tokens.
    """
    min_stop_index = len(decoded_string)
    for stop_token in problem["stop_tokens"]:
        stop_index = decoded_string.find(stop_token)
        if stop_index != -1 and stop_index > len(problem["prompt"]) and stop_index < min_stop_index:
            min_stop_index = stop_index
    return decoded_string[:min_stop_index]

for problem in problems["test"]:
    input_ids = tokenizer(
        problem["prompt"],
        return_tensors="pt",
    ).input_ids.cuda()
    generated_ids = model.generate(
        input_ids, max_length=256, pad_token_id=tokenizer.eos_token_id + 2
    )
    truncated_string = stop_at_stop_token(tokenizer.decode(generated_ids[0]), problem)
    filename = problem["name"] + "." + LANG
    with open(filename, "w") as f:
        print(f"Created {filename}")
        f.write(truncated_string)
        f.write("\n")
        f.write(problem["tests"])
```
