In some instances, we might have to install packages that do not come prebuilt. The setup.py file comes in handy in such scenarios:

from setuptools import setup, find_packages
setup(name='mnist_mlp_lr_numsteps',
      version='1.0',
      packages=find_packages(),
      include_package_data=True,
      install_requires=[
          'keras',
          'h5py'],
      zip_safe=False)

In the preceding code, one could include the additional packages that are needed to run the model file.
