I run 'sh compile_op.sh'. Then it works.

@yaping222 how did you run it? it gives me this error

Traceback (most recent call last):
  File "setup.py", line 3, in <module>
    from Cython.Distutils import build_ext
ImportError: No module named Cython.Distutils

However, I have Cython installed !

事先运行 sh compile_op.sh

Right,you should pip install cypyton firstly,after that run sh compile_op.sh
