# ------------------------------------------------------------------------------------ #
# `pyrootutils.setup_root(...)` is recommended at the top of each start file
# to make the environment more robust and consistent
#
# the line above searches for ".git" or "pyproject.toml" in present and parent dirs
# to determine the project root dir
#
# adds root dir to the PYTHONPATH (if `pythonpath=True`)
# so this file can be run from any place without installing project as a package
#
# sets PROJECT_ROOT environment variable which is used in "configs/paths/default.yaml"
# this makes all paths relative to the project root
#
# additionally loads environment variables from ".env" file (if `dotenv=True`)
#
# you can get away without using `pyrootutils.setup_root(...)` if you:
# 1. move this file to the project root dir or install project as a package
# 2. modify paths in "configs/paths/default.yaml" to not use PROJECT_ROOT
# 3. always run this file from the project root dir
