Hi to all! I am trying to cythonize some code including operations on numpy arrays. Following the user manual I declared the type of the arrays and tried to compile, which fails with a syntax error message for which I can't see any reason. It appears not to like the [] in my declaration (or at least notto find the closing ]. I tried compiling without using the DTYPE declaration at all (np.ndarray without specified type) and it works, but of course the speed gain is not much.
Any clue? Thanks in advance for your help JF The abridged code: > > DTYPE = np.int > > ctypedef np.int_t DTYPE_t > > > > ... > > > > #[email protected](False) #commented just to see if solves the problem...
