Here is the change you need to make:

```bash
benchmark/docker.sh
<<<<<<< ORIGINAL

=======
#!/bin/bash
docker run -it --rm python:3.8 bash
>>>>>>> UPDATED

This script will start a Docker container using the Python 3.8 image and launch bash. You can run this script from the terminal with the command `./benchmark/docker.sh`. Make sure the script has execute permissions. You can add them with the command `chmod +x benchmark/docker.sh` if needed.
