pip install openjij \n# From Source\n$ pip install --no-binary=openjij openjij\n```\n\n### install via pip from source codes\n\nTo install OpenJij from source codes, please install CMake first then install OpenJij.\n\n#### cmake setup\n\nIf you want to use setup.py instead of PIP, You will need to install CMake\u003e=3.22.\\\nWe are Highly recommended install CMake via PYPI.\n\n```\n$ pip install -U cmake\n```\n\nMake sure the enviroment path for CMake is set correctly.\n\n#### install OpenJij\n\n```\n$ pip install --no-binary=openjij openjij\n```\n\n### install from github repository\n\n```\n$ git clone git@github.com:OpenJij/OpenJij.git\n$ cd openjij\n$ python -m pip install -vvv .\n```\n\n## For Contributor\n\nUse `pre-commit` for auto chech before git commit.\n`.pre-commit-config.yaml`\n\n```\n# pipx install pre-commit \n# or \n# pip install pre-commit\npre-commit install\n```\n\n## Test\n\n### Python\n\n```sh\n$ python -m venv .venv\n$ .

lint-requirements.txt\n```\n\n```sh\n$ python -m flake8\n$ python -m mypy\n$ python -m pyright\n```\n\n## Python Documentation \nUse Juyter Book for build documentation.   \nWith KaTeX    \nNeed: Graphviz\n\n``` sh\n$ pip-compile setup.cfg\n$ pip-compile build-requirements.in\n$ pip-compile doc-requirements.in\n$ pip-sync requirements.txt build-requirements.txt doc-requirements.txt\n```\n\nPlease place your document to `docs/tutorial`either markdown or jupyter notebook style.\n\n```sh\n$ pip install -vvv .\n```\n\n```sh \n$ jupyter-book build docs --all\n```\n\n\n## How to use\n\n### Python example\n\n```python\nimport openjij as oj\nsampler = oj.SASampler()\nresponse = sampler.sample_ising(h={0: -1}, J={(0,1): -1})\nresponse.states\n# [[1,1]]\n\n# with indices\nresponse = sampler.sample_ising(h={'a': -1}, J={('a','b'): 1})\n[{index: s for index, s in zip(response.indices, state)} for state in response.states]\n# [{'b': -1, 'a': 1}]\n```\n\n## Community\n\n- [OpenJij Discord Community](https://discord.gg/Km5dKF9JjG)\n\n## About us\n\nThis product is maintained by Jij Inc.\n\n**Please visit our website for more
