can you check if you have the folder cached_klines in the same directory where you are running the command?

Good catch !

Maybe adding something like

import pathlib

...

        cached_klines_path = pathlib.Path(CACHED_KLINES_PATH)
        p.mkdir(parents=True, exist_ok=False)
        file_out = cached_klines_path / file_out_1

could help

PS : pathlib is great https://docs.python.org/3/library/pathlib.html
