.. _python-install: Installing aubio for Python=========================== aubio is available as a package for Python 2.7 and Python 3. The aubioextension is written C using the `Python/C`_ and the `Numpy/C`_ APIs. .. _Python/C: https://docs.python.org/c-api/index.html.. _Numpy/C: https://docs.scipy.org/doc/numpy/reference/c-api.html For general documentation on how to install Python packages, see `InstallingPackages`_. Installing aubio with pip------------------------- aubio can be installed from `PyPI`_ using ``pip``: .. code-block:: console     $ pip install aubio See also `Installing from PyPI`_ for general documentation. .. note::   aubio is currently a `source only`_ package, so you will need a compiler to  install it from `PyPI`_. See also `Installing aubio with conda`_ for  pre-compiled binaries. .. _PyPI: https://pypi.python.org/pypi/aubio.. _Installing Packages: https://packaging.python.org/tutorials/installing-packages/.. _Installing from PyPI: https://packaging.python.org/tutorials/installing-packages/#installing-from-pypi.. _source only: https://packaging.python.org/tutorials/installing-packages/#source-distributions-vs-wheels Installing aubio with conda--------------------------- `Conda packages`_ are available through the `conda-forge`_ channel for Linux,macOS, and Windows: .. code-block:: console     $ conda config --add channels conda-forge    $ conda install -c conda-forge aubio .. _Conda packages: https://anaconda.org/conda-forge/aubio.. _conda-forge: https://conda-forge.org/ .. _py-doubleprecision: Double precision---------------- This module can be compiled in double-precision mode, in which case thedefault type for floating-point samples will be 64-bit. The default issingle precision mode (32-bit, recommended). To build the aubio module with double precision, use the option`--enable-double` of the `build_ext` subcommand: .. code:: bash     $ ./setup.py clean    $ ./setup.py build_ext --enable-double    $ pip install -v . **Note**: If linking against `libaubio`, make sure the library was alsocompiled in :ref:`doubleprecision` mode.  Checking your installation-------------------------- Once the python module is installed, its version can be checked with: .. code-block:: console     $ python -c "import aubio; print(aubio.version, aubio.float_type)" The command line `aubio` is also installed: .. code-block:: console     $ aubio -h  Python tests------------ A number of Python tests are provided in the `python tests`_. To run them,install `nose2`_ and run the script ``python/tests/run_all_tests``: .. code-block:: console     $ pip install nose2    $ ./python/tests/run_all_tests .. _demo_filter.py: https://github.com/aubio/aubio/blob/master/python/demos/demo_filter.py.. _python tests: https://github.com/aubio/aubio/blob/master/python/tests.. _nose2: https://github.com/nose-devs/nose2
