title: Cython ImportError: No module named parallel
body: <p>I am trying to access the new parallel features of Cython 0.15 (using
  Cython 0.15.1). However, if I try this minimal example (testp.py), taken from <a href="http://docs.cython.org/src/userguide/parallelism.html" rel="nofollow">http://docs.cython.org/src/userguide/parallelism.html</a>:</p>
  
  <pre><code>from cython.parallel import prange, parallel, threadid
  cdef int i
  cdef int sum = 0
  
  for i in prange(n, nogil=True):
      sum += i
  print sum
  </code></pre>
  
  <p>with this setup.py:</p>
  
  <pre><code>from distutils.core import setup
  from distutils.extension import Extension
  from Cython.Distutils import build_ext
  import numpy
  
  ext = Extension("testp", ["testp.pyx"], include_dirs=[numpy.get_include()],
                  extra_compile_args=['-fopenmp'], extra_link_args ['-fopenmp'])
  setup(ext_modules=[ext], cmdclass={'build_ext': build_ext})
  </code></pre>
  
  <p>when I <code>import testp</code>, Python tells me: <code>ImportError: No module named
  parallel</code>. And in fact, if I browse the Cython package in the
  site-packages, I cannot find any file or directory that is called
  <code>parallel</code>. But I thought it should be included somewhere in the
  release? Could someone please clarify for a confused user?</p>
