Loading config.jon from egg file on Airflow

How can I load a config file from an egg file? I'm trying to run python code that is packages as egg file on Airflow. In the code, it tries to load a config.json file which fails to run on Airflow. I guess the issue is that it tries to read the file from the egg file and since it is zipped it can't find it. I updated as follow to make sure the config file is in the pckage:

from setuptools import find_packages, setup

    description='Quality checks on IPTV linear viewing data',
    author='Sarah Berenji',
    data_files=[('src/codes', ['src/codes/config.json'])],

Now it complains that the config_file_path is not a directory:

NotADirectoryError: [Errno 20] Not a directory: '/opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json'

I checked the path and the json file is on there. Here is my code with some print statement added to debug which shows that it doesn't see config_file_path as a file or a directory:

dir_path = os.path.dirname(__file__)
config_file_path = dir_path + '/config.json'

print(f"config_file_path = {config_file_path}")
print(f"relpath(config_file_path) = {os.path.relpath(config_file_path)}")

if not os.path.isfile(config_file_path):
    print(f"{config_file_path} is not a file")
if not os.path.isdir(config_file_path):
    print(f"{config_file_path} is not a dir")

with open(config_file_path) as json_file:
    config = json.load(json_file)

It returns the following outputs:

config_file_path = /opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json
relpath(config_file_path) = ../../artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json
/opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json is not a file
/opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json is not a dir

Traceback (most recent call last):

NotADirectoryError: [Errno 20] Not a directory: '/opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json'

As my next try, I tried to use importlib_resources but ended up to the weird error that the module is not installed but the log show it was successfully installed by pip: ModuleNotFoundError: No module named 'importlib_resources'

import importlib_resources

config_file = importlib_resources.files("") / "config.json"
with open(config_file) as json_file:
    config = json.load(json_file)


  • I just managed to do it using pkg_resources:

    config_file = pkg_resources.resource_stream('', 'config.json')
    config = json.load(config_file)
