How to install dependencies of a custom python package

I have built a Python package according to the documentation: https://packaging.python.org/en/latest/tutorials/packaging-projects/

Everything works, but when I call pip install my_package.whl, the dependencies are not installed.

The dependencies are listed in the pyproject.toml file as follows: requires = ["hatchling", "package1", "package2"]

Question 1. During the build, I can see the following log:

* Installing packages in isolated environment... (hatchling, pydicom~=2.3.1)

What does it mean the dependencies installed and for what purpose?

Question 2. How to achieve the behavior, where after typing 'pip install my_package.whl', the required dependencies are installed beforehand. This must be possible, becaus all of the available python packages work this way.

require is for build time dependencies.

You want to use dependencies for runtime ones.

i.e.

dependencies = ["package1", "package2"]

I've managed to solve it in the meantime.

Q1: These are packages required during the build, not for using the package.

Q2: Use setuptool and the setup.py file instead of pyproject.toml The content of the file is in my case:

from setuptools import setup

setup(
    name='my_package',
    version='1.0.0',
    description='Description',
    author='Karol',
    packages=['my_package'],
    install_requires=[
        'numpy~=1.23.4',
        'pillow~=9.3.0',
        'pydicom~=2.3.1'
    ],
    zip_safe=False
)
