Dataset Card for "openai_humaneval_alpaca_style"

This dataset consists of hand-written Python solutions to 164 programming problems by OpenAI. This dataset is equivalent to openai_humaneval, but has been slightly modified to fit the Alpaca format and include an input field ("The prompt's code is written in Python. Write corresponding response code in Python, as well.") when Python is not explicitly mentioned in the prompt.
