मैं निम्नलिखित कोड है कि propperly cython को परिवर्तित किया हैNumpy-> Cython रूपांतरण: संकलित करें त्रुटि: कनवर्ट नहीं कर सकता 'npy_intp *' अजगर वस्तु को
from numpy import *
## returns winning players or [] if undecided.
def score(board):
scores = []
checked = zeros(board.shape)
for i in xrange(len(board)):
for j in xrange(len(board)):
if checked[i,j] == 0 and board[i,j] !=0:
... do stuf
रूपांतरण पर मेरे प्रयास cython रहे हैं:
import numpy as np
cimport numpy as np
@cython.boundscheck(False)
@cython.wraparound(False)
@cython.nonecheck(False)
## returns winning players or [] if undecided.
def score(np.ndarray[int, ndim=2] board):
scores = []
cdef np.ndarray[int, ndim = 2 ] checked
checked = np.zeros(board.shape)
for i in xrange(len(board)):
for j in xrange(len(board)):
if checked[i,j] == 0 and board[i,j] !=0:
... do stuf
लेकिन जब मैं संकलन मैं:
$ python setup.py build_ext --inplace
running build_ext
cythoning newgox.pyx to newgox.c
## returns winning players or [] if undecided.
def score(np.ndarray[int, ndim=2] board):
scores = []
cdef np.ndarray[int, ndim = 2 ] checked
checked = np.zeros(board.shape)

newgox.pyx:58:28: Cannot convert 'npy_intp *' to Python object

इसके अलावा, मुझे यकीन है कि यह सही तरीके से फूल के साथ काम करने है नहीं कर रहा हूँ cython में ts:
scores = []
if some_stuff_is_true:
scores.append(some_integer)
संपादित करें:
धन्यवाद, कोड अब संकलित लेकिन जब मैं इसे चलाने मैं त्रुटि मिलती है:
ctypedef np.int_t DTYPE_t
DTYPE = np.int
File "newgox.pyx", line 63, in newgox.score (newgox.c:1710)
def score(np.ndarray[np.int, ndim=2] board):
ValueError: Buffer dtype mismatch, expected 'int object' but got 'long'
और फिर जारी रखें:
board = zeros((5,5), dtype = DTYPE)
def score(np.ndarray[DTYPE, ndim=2] board):
या सिर्फ दोनों घोषणाओं में:
... np.int ...
यह वही त्रुटि में परिणाम है, लेकिन हस्ताक्षर के साथ:
ValueError: Buffer dtype mismatch, expected 'int' but got 'long'
धन्यवाद bellamyj, लेकिन आपके द्वारा सुझाए गए कोड को संकलित नहीं होगा,

और कुछ और:
है तो मुझे इस बताता है।

newgox.c:2420: error: too many arguments to function ‘__pyx_f_6newgox_check_life’
लेकिन स्कोर से मेरे कॉल/1 check_life के लिए है:
life, newly_checked = check_life(i,j,board,[])
और यह इस तरह प्राप्त होता है:
# helper functions of score/1
cdef check_life(int i, int j, np.ndarray[int, ndim=2] board, checked):
...
return life, checked
अंत में, क्या किस तरह का डेटा प्रकार "i4" है जिसका आप उपयोग करते हैं?
