copytree's dirs_exist_ok parameter is only available in Python 3.8+

Line 174 in 3aec6a7

shutil.copytree(self.script_path, trainer_path, dirs_exist_ok=True)

See https://docs.python.org/3/whatsnew/3.8.html#shutil

Need to replace with something else to support <3.8 or else an exception occurs.

TODO:

• Replace shutil.copytree with something more compatible
• Add unit test to cover passing in a folder to _TrainingScriptPythonPackager

A potential workaround for <3.8: https://stackoverflow.com/a/31039095

Unfortunately, "distutils has been deprecated in Python 3.10 and is planned to be removed in 3.12, see PEP 632 for info."

Perhaps https://stackoverflow.com/a/12514470 would work across versions.

Yup, and another option is to check if sys.version_info < (3, 8) to only apply the workaround in the post you mentioned on 3.6 and 3.7.
