> According to the reference of python, {{os.removedirs}} doesn't work if there
> are any files in the directory we want to remove.
> https://docs.python.org/3/library/os.html#os.removedirs
> Instead of that, using {{shutil.rmtree()}} would be better to remove a
> temporary directory to test for saving model.
