How can I integrate the Ordinary differential equation using odeint from scipy.integrate?

Question

I am trying to integrate function defined as f in the code using odeint from scipy. The function f takes theta, t, and K as arguments, which are defined below the function f. y is the result, for which I am getting error. The reason for error is theta which is 2 dimensional. I am not able to perform integration. Could somebody help me in this ?

import numpy as np
import random
from scipy.integrate import odeint

f is function to be integrated

def f(theta, t, K):
    global N   
    tau = 1.5  
    dtheta = np.zeros([T,N], float)  
    for i in range(N):  
        s = 0.  
        for j in range(i+1,N):  
            s = s + np.sin(theta[t-tau,j] - theta[t,i])  
        dtheta[t,i] = K*s  
    return dtheta  

# Number of nodes
N = 10
# Constant
K = 1.0
# Number of time steps 
T = 100
t = np.linspace(0, T, 100, endpoint=False)
theta = np.zeros([T,N], float)

Uniformly generates random number

for i in range(N):
    theta[0,i] = random.uniform(-180, 180)  

Integrate function f using odeint from scipy

y = odeint(f, theta, t, args=(K,))
print y

Answer 1

Write

y = odeint(f, theta.ravel(), t, args=(K,))

and

def f(theta, t, K):
    global N
    theta = theta.reshape(T, N)
    ...
    return dtheta.ravel()
