Build Requirements ------------------ * `Python >= 2.5 <http://python.org>`__ * `Numpy >= 1.6 <http://numpy.scipy.org/>`__ * `Cython >= 0.17 <http://www.cython.org/>`__ `Matplotlib >= 1.0 <http://matplotlib.sf.net>`__ is needed to generate the examples in the documentation. You can use pip to automatically install the base dependencies as follows:: $ pip install -r requirements.txt Runtime requirements -------------------- * `SciPy >= 0.10 <http://scipy.org>`__ Known build errors ------------------ On Windows, the error ``Error:unable to find vcvarsall.bat`` means that distutils is not correctly configured to use the C compiler. Modify (or create, if not existing) the configuration file ``distutils.cfg`` (located for example at ``C:\Python26\Lib\distutils\distutils.cfg``) to contain:: [build] compiler=mingw32 Usage Requirements ------------------ * `Scipy <http://www.scipy.org/>`__ Optional Requirements --------------------- You can use this scikit with the basic requirements listed above, but some functionality is only available with the following installed: * `PyQt4 <http://wiki.python.org/moin/PyQt>`__ The ``qt`` plugin that provides ``imshow(x, fancy=True)`` and `skivi`. * `FreeImage <http://freeimage.sf.net>`__ The ``freeimage`` plugin provides support for reading various types of image file formats, including multi-page TIFFs. * `PyAMG <http://pyamg.org/>`__ The ``pyamg`` module is used for the fast `cg_mg` mode of random walker segmentation. * `Pillow <https://pypi.python.org/pypi/Pillow>`__ (or `PIL <http://www.pythonware.com/products/pil/>`__) The ``Pillow`` library (or equivalently ``PIL``) is used for Input/Output. * `Astropy <http://www.astropy.org>`__ is required to use the FITS io plug-in. Testing requirements -------------------- * `Nose <https://nose.readthedocs.org/en/latest/>`__ A Python Unit Testing Framework * `Coverage.py <http://nedbatchelder.com/code/coverage/>`__ A tool that generates a unit test code coverage report
