Thoth Solver

Dependency solver used in Thoth project.

Project Scope

The aim of this project is to answer a simple question - what packages will be installed (resolved by pip) for the provided stack?

Imagine you have an application that has one dependency:

$ cat requirements.txt
tensorflow

This project will tell you how dependencies could be resolved:

thoth-solver -vvv pypi -r requirements.txt

The output can be found at here.

You can optionally also specify a list of indexes which should be checked for each package.

Installation and Deployment

git clone git@github.com:thoth-station/solver.git thoth-solver
cd thoth-solver
PYTHONPATH='.' ./thoth-solver-cli --help

This project is also released on PyPI, so the latest release can be installed via pip or Pipenv:

pipenv install thoth-solver

Solver is run in Thoth to gather information about package dependencies. You can find deployment templates in the openshift/ directory present in the root of solver’s Git repository. The actual deployment is done using Ansible playbooks available in the Thoth’s core repository.
