data_root = os.path.abspath(os.path.join(os.getcwd(), "../.."))

This code snippet creates a variable called `data_root` that stores the absolute path of the parent directory of the current working directory.

Here's how it works:

- `os.getcwd()` returns the current working directory as a string.
- `os.path.join()` joins the current working directory with the relative path `"../.."` which represents the parent directory of the current directory.
- `os.path.abspath()` returns the absolute path of the joined path. This ensures that the path is in a standardized format with all symbolic links resolved and any relative paths converted to absolute paths.

Overall, this code is useful for navigating to a specific directory relative to the current working directory, regardless of where the code is run from.
