Custom python package not found

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',

        )
