• app_name and app_version are used to log information of current version.
  • It is useful if app_version is set to __version__ of the app.
• app_file is used to check the file place's git status to log the git commit hash and diff from the last commit.
• The argument which the main function takes is dict[Any, Any] instead of DictConfig.
• Configuration file can be passed by the first argument or conf=... at the command line.
• Configuration file can have include keyword which has the list of configuration files to include.
  • Included files are merged to the main configuration file.
  • It is resolved at the place of include. If the main file has other configurations after the include, they will overwrite the included configurations.
• n_jobs is fixed to the number of CPUs.
  • It is used to set the number of jobs for parallel processing.
  • If n_jobs is set to 0 or 1, it is set to 1.
  • If n_jobs is set to -1, it is set to the number of logical cores.
  • If n_jobs is set to None, it is set to the number of physical cores.
  • If n_jobs is set to a negative number, it is set to the number of logical cores + 1 + n_jobs, i.e. -1 is the same as the number of logical cores.

There is also wrapper function for to_absolute_path.

from hydra_utils import to_absolute_path

• It returns empty string if the input is empty.
• It returns the input as is if the input includes : (e.g., http://, s3://, ...).
