Index error not resolving

#1

i am getting an index error on my code:
def hypothesis(x, theta):
return theta[0]+theta[1]x
def error(X,Y,theta):
total_error = 0
m = X.shape[0]
for i in range(m):
total_error+=(y[i]-hypothesis(x[i],theta))**2
return 0.5total_error
def gradient(X,Y,theta):
grad = np.array([0.0,0.0])
m = X.shape[0]
for i in range(m):
grad[0]+=-1*(y[i]-hypothesis(theta,x[i]))
grad[1]+=-1*(y[i]-hypothesis(theta,x[i]))x[i]
return grad
def gradientdescent(X,Y,learning_rate,maxitr):
grad = np.array([0.0,0.0])
theta = np.array([0.0,0.0])
for i in range(maxitr):
grad = gradient(X,Y,theta)
theta[0] = theta[0]-learning_rategrad[0]
theta[1] = theta[1]-learning_rate*grad[1]
return theta
theta = gradientdescent(X,Y,learning_rate = 0.001,maxitr = 50)
print(theta)

Hi @chirag10,
It would be really difficult for anyone to understand code here.
I suggest you to copy paste the code in coding blocks ide and share the link here.
Also, please attach a screenshot at which line index error is occuring, I will directly see that piece of code, instead of scanning all the functions.
