Thank you for the module. I made simple test file cython_study.pyx:

cpdef int test(int x):
    cdef int y = 0
    cdef int i
    for i in range(x):
        y += i
    return y

command cythonizer cython_study.pyx compiles the file successfully, but when I run import cython_study there's 'ModuleNotFoundError'. On the other hand, if I use conventional setup.py & python setup.py build_ext --inplace:

from distutils.core import setup
from Cython.Build import cythonize

setup(ext_modules = cythonize('cython_study.pyx'))

the import cython_study runs without errors. The observed difference is in output files at compilation. In cythonizer case output was: cython_study.pypy36-pp73-x86_64-linux-gnu.so and in conventional was: cython_study.cpython-36m-x86_64-linux-gnu.so.

I'm still at learning stage, so any idea how to solve import the cython_study.pypy36-pp73-x86_64-linux-gnu.so or solve the problem? Thank you.

Thank you for making it easy to use Cython.

by the way,

Is there an obligation to notify MIT license for the result of converting my Python project to pyd through cythonizer?

I want you to clearly. Thank you.
