Custom python package not found

Question

I followed this tutorial from python.org and managed to upload to PyPI and install with pip but all I get is

ModuleNotFoundError: No module named 'tomaszslittlehelpers'

Any suggestions?

The import works locally that is when imported from a file in a folder above.

package name is tomaszslittlehelpers

setup.py:

import setuptools

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

setuptools.setup(
        name='tomaszslittlehelpers',
        version='0.0.2',
        author='TomaszAndrzej',
        author_email='',
        description='Tomasz\'s Little Helpers',
        long_description=long_description,
        long_description_content_type='text/markdown',
        url='',
        packages=setuptools.find_packages(),
        classifiers=[
                'Programming Language :: Python :: 3',
                'License :: OSI Approved :: MIT License',
                'Operating System :: OS Independent',
                ],
        python_requires='>=3.7',

        )

__init__.py:

name='tomaszslittlehelpers'

Project tree:

pip install tomaszslittlehelpers
installs into

Hi @Tomasz. It'd be good to get more specifics on this. What is the package called on PyPI? Please also share the setup.py file so we can see how you're attempting to build it. — John Adjei

It sounds like an issue with the location of the installed package. I can see the package on pypi.org so it must be an issue with where the package is installed locally. — deprekate

Somewhere along the way you did something like python setup.py build to create an archive in dist/ that you uploaded, right? I'd bet that the package you created has no Python files in it because setuptools.find_packages() didn't find anything. — Kirk Strauser

If you can show the directory tree of your project that would help. You probably want an empty tomaszslittlehelpers/__init__.py in your package. — askaroni

There is an issue with your packaging. Your code is not added to your distributions. You are using packages=setuptools.find_packages(), but there doesn't seem to be any package to look for. It looks like your code is in the __init__.py file at the root of your project. This most likely won't work.

Two solutions:

Rename your __init__.py to tomaszslittlehelpers.py and replace packages=setuptools.find_packages(), with py_modules=['tomaszslittlehelpers'],.
Move your __init__.py to a tomaszslittlehelpers subdirectory, and find_packages() should be able to find it.

In both cases you should then be able to import your code like this: import tomaszslittlehelpers.

If you look on pypi and download your release You can see that in this release there are no python files included

As @kirk-strauser mentioned. This is most likely because setuptools.find_packages() didn't find any packages
