Dear developer of cython,
First of all I thank you for all your work. Thanks to Cython and the
documentation and tutorial that you displayed on internet, I have
successfully managed to create a cython code approximately 250 times
quicker than with python and even 1.4times quicker than C.
In fact I created two cython codes corresponding to two python codes of
the same algorithm (one with a single function and one with several
classes and function).
I hesitated several minutes before posting in this list or in the user
list but since this is not simple cython problem but a problem with the
new version of cython, i have finally chosen to post here. I hope I made
the right choice.
I downloaded the version 0.13 of cython yesterday (I was previously using
the version 0.12.1) and two problems appeared when I used cython.
The first one is that it seems that we can no more combine cpdef and
decorator :
@cython.boundscheck(False)
@cython.wraparound(False)
cpdef run(self,adjacencyMatrix_,nodesPosition_,int dimension,nbLink_):
^
------------------------------------------------------------
/homelocal/max/Memoire/Sources/CAttractionRepulsionAlgorithm.pyx:48:4:
Decorators can only be followed by functions
I have the same problem with cdef and I have not the problem with def.
The second problem is that it seems that we can nore more used
@cython.wraparound(False).
I have this error
@cython.wraparound(False)
^
------------------------------------------------------------
/homelocal/max/Memoire/Sources/CAttractionRepulsionAlgorithm.pyx:47:4:
'wraparound' not a valid cython attribute or is being used incorrectly
and this error for the same line :
@cython.wraparound(False)
^
------------------------------------------------------------
/homelocal/max/Memoire/Sources/CAttractionRepulsionAlgorithm.pyx:47:4:
'wraparound' not a valid cython language construct
The use of this decorator with cpdef is important for me since it speed up
my cython code by nearly a factor 2.
Max.
