Sometimes we may need to import python files in another path, such as the following directory structure, where we want to import _lstm.py in _train.py in the networks directory and _config.py in the parent directory.
_config.py networks _lstm.py _cnn.py pipelines _train.py
Just two steps
(1) Create an empty __init__.py file in the networks folder
_config.py networks _lstm.py _cnn.py pipelines _train.py
(2) Add a path using the sys library
# _train.py
import sys
("..") # This sentence is for importing _config
from networks._lstm import *
from _config import *
update
Some students have reported that the Python 3.6.7+ method fails. An inelegant workaround is given here, which essentially recursively traverses the file path and adds to the referenced path.
The full test code can be found at/SongDark/Import_Test
# _train.py
import sys, os
("..")
([(root, name) for root, dirs, _ in ("../") for name in dirs])
