• Parameters:path (str or Path) – Path to the file.
• Returns: A list of stripped lines from the file.
• Return type: List[str]
• Raises:
  • FileNotFoundError – If path does not exist.
  • PermissionError – If the file cannot be read.

>>> cfg = OmegaConf.create({"vocab": "${load_line:tokens.txt}"})
