-> [!WARNING]
-> Please use BigCodeBench with caution. Different from [EvalPlus](https://github.com/evalplus/evalplus), BigCodeBench has a much less constrained execution environment to support tasks with diverse library dependencies. This may lead to security risks. We recommend using a sandbox such as [Docker](https://docs.docker.com/get-docker/) to run the evaluation.
