How to pass a numpy array of string types to a function in Cython

Question

Passing a numpy array of dtype np.float64_t works fine ( below), but I can\'t pass string arrays.

This is what works :

# c         


        

Answer 1

With Cython 0.20.1 it works using cdef np.ndarray, without specifying the data type and the number of dimensions:

import numpy as np
cimport numpy as np

cdef func1(np.ndarray A):
    print A

def testing():
    chunk = np.array([['huh','yea'], ['swell','ray']])
    func1(chunk)
