-Dependencies
-------------
-
-Runtime dependencies
-~~~~~~~~~~~~~~~~~~~~
-
-Scikit-learn requires the following dependencies both at build time and at
-runtime:
-
-- Python (>= |PythonMinVersion|),
-- NumPy (>= |NumpyMinVersion|),
-- SciPy (>= |ScipyMinVersion|),
-- Joblib (>= |JoblibMinVersion|),
-- threadpoolctl (>= |ThreadpoolctlMinVersion|).
-
-Build dependencies
-~~~~~~~~~~~~~~~~~~
-
-Building Scikit-learn also requires:
-
-- Cython >= |CythonMinVersion|
-- A C/C++ compiler and a matching OpenMP_ runtime library. See the
-  :ref:`platform system specific instructions
-  <platform_specific_instructions>` for more details.
-
-.. note::
-
-   If OpenMP is not supported by the compiler, the build will be done with
-   OpenMP functionalities disabled. This is not recommended since it will force
-   some estimators to run in sequential mode instead of leveraging thread-based
-   parallelism. Setting the ``SKLEARN_FAIL_NO_OPENMP`` environment variable
-   (before cythonization) will force the build to fail if OpenMP is not
-   supported.
-
-Since version 0.21, scikit-learn automatically detects and uses the linear
-algebra library used by SciPy **at runtime**. Scikit-learn has therefore no
-build dependency on BLAS/LAPACK implementations such as OpenBlas, Atlas, Blis
-or MKL.
-
-Test dependencies
-~~~~~~~~~~~~~~~~~
-
-Running tests requires:
-
-- pytest >= |PytestMinVersion|
-
-Some tests also require `pandas <https://pandas.pydata.org>`_.
