Module not found after setuptools

I have a setup.py file below and I

maindir
   |- setup.py
   |-src
         |- __init__.py
         |- pipeline.py
         |- parameter.py

and 

import setuptools

with open("README.md", "r") as fh:
    long_description = fh.read()

setuptools.setup(
    classifiers=[
        'Programming Language :: Python',
        'Development Status :: 4 - Beta',
        'Environment :: Console',
        'Intended Audience :: Science/Research',
        'License :: OSI Approved :: GNU General Public License (GPL)'
    ],  
    packages=setuptools.find_packages(),
    license='LICENSE.txt',
    long_description=open('README.md').read(),
    entry_points={'console_scripts': ['step1 = src.pipeline:step1']}
)

where pipeline.py has import parameter at the top.

I ran python setup.py install but afterwards it said it couldn't find the module parameter.py. So then instead of using packages = find_packages() I used packages=['src/parameter','src'] but then I have to change import parameter to import src.parameter. Is there anyway to avoid this?

Solution

  • You don't have any packages under src so find_packages() doesn't find any. Listing 'src/parameter' as a package is meaningless as it's not a package (a directory with file __init__.py), it's a module. Only 'src' is a package here.

    I have to change import parameter to import src.parameter

    Python 3, I suppose? Python 3 prefers absolute import but allows relative import. So either use import src.parameter or import .parameter

    import parameter is an absolute import in Python 3 (in Python 2 it was relative+absolute import), i.e. Python searches through sys.path to find parameter and fails.
