我有一个完美的python程序，我想在这个程序中使用Cython来实现一个函数。
原始功能是：
def NoFeedB(Ef, Ef2, Nf, u, tijd ):
dEdt= np.zeros_like(Ef, dtype=np.complex128)
dNdt= np.zeros_like(Nf)
Efcon = np.conjugate(Ef)
for j in xrange(nrModes):
for n in xrange(nrMoments):
dEdt = dEdt + 0.5 * CouplingE((j+1,n,0)) * dg * (1+ A*1j) * Nf[n] * Ef[j] * np.exp( 1j* (sweep.omega[j]-sweep.omega) *tijd)
for k in xrange(nrModes):
if n==0:
dNdt = dNdt + (g* CouplingN((j+1, k+1, 0 )) * Efcon[j] * Ef[k] * np.exp( 1j* (sweep.omega[k]-sweep.omega[j]) *tijd) )
dNdt = dNdt + ( dg*(1+A*1j) * CouplingN((j+1,k+1,n)) * Nf[n] * Efcon[j] * Ef[k] * np.exp( 1j* (sweep.omega[k]-sweep.omega[j]) *tijd) )
dEdt = dEdt - 0.5*(pd-g)*Ef
dNdt = sweep.Jn - Nf*ed - np.real(dNdt)
return dEdt, dNdt
看看这两个网站： http://docs.cython.org/src/tutorial/cython_tutorial.html#primes 和 http://docs.cython.org/0.14/src/tutorial/numpy.html我将代码更改为：
def NoFeedB( np.ndarray[np.complex128_t,ndim= nrModes] Ef, np.ndarray[np.complex128_t,ndim= nrModes] Ef2, np.ndarray[np.complex128_t,ndim= nrMoments]Nf, np.ndarray[np.float64_t,ndim= nrModes] u, float tijd ):
cdef np.ndarray[np.complex128_t,ndim= nrModes] dEdt = np.zeros(nrModes,dtype=np.complex128)
cdef np.ndarray[np.complex128_t,ndim= nrMoments] dNdt= np.zeros(Nf, float64)
cdef np.ndarray[np.complex128_t,ndim= nrModes] Efcon = np.conjugate(Ef)
cdef Py_ssize_t j,n,k
for j in xrange(nrModes):
for n in xrange(nrMoments):
dEdt = dEdt + 0.5 * CouplingE((j+1,n,0)) * dg * (1+ A*1j) * Nf[n] * Ef[j] * np.exp( 1j* (sweep.omega[j]-sweep.omega) *tijd)
for k in xrange(nrModes):
if n==0:
dNdt = dNdt + (g* CouplingN((j+1, k+1, 0 )) * Efcon[j] * Ef[k] * np.exp( 1j* (sweep.omega[k]-sweep.omega[j]) *tijd) )
dNdt = dNdt + ( dg*(1+A*1j) * CouplingN((j+1,k+1,n)) * Nf[n] * Efcon[j] * Ef[k] * np.exp( 1j* (sweep.omega[k]-sweep.omega[j]) *tijd) )
dEdt = dEdt - 0.5*(pd-g)*Ef
dNdt = sweep.Jn - Nf*ed - np.real(dNdt)
return dEdt, dNdt
现在我收到了这个错误：
TypeError: %d format: a number is required, not NoneType

完成错误消息:(我的functions.pyx文件中没有提到错误发生在哪一行）
