Python 从气流上的egg文件加载config.jon

如何从egg文件加载配置文件？我正在尝试运行python代码，该代码是以文件包的形式在Airflow上运行的。在代码中，它尝试加载一个config.json文件，但该文件无法在Airflow上运行。我猜问题是它试图从egg文件中读取文件，但由于它已压缩，因此找不到它。我更新了setup.py，如下所示，以确保配置文件位于pckage中：

from setuptools import find_packages, setup

setup(
    name='tv_quality_assurance',
    packages=find_packages(),
    version='0.1.0',
    description='Quality checks on IPTV linear viewing data',
    author='Sarah Berenji',
    data_files=[('src/codes', ['src/codes/config.json'])],
    include_package_data=True,
    license='',
)

现在它抱怨

config\u file\u path

不是目录：

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

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)

我检查了路径，json文件就在那里。下面是我的代码，在调试中添加了一些print语句，这表明它没有将

config\u file\u path

视为文件或目录：

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

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)

它返回以下输出：

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

我只是设法用

pkg_资源
：

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