Hi I am running Jupyter Notebook on my local machine but got the following error when I tried to run the cell. Can I ask for some help? Many thanks in advance.

Hi @rebecca.mun

Welcome to the community!

This error raise because your numbers output are greater than `sys.maxsize`

:

```
import sys
print(sys.maxsize)
```

the solution is to convert the cost list to float data type like this

```
import numpy as np
cost =[]
# Sample NumPy array of integers
int_array = np.array(cost )
# Convert the elements of the array to float
float_array = int_array.astype(float)
cost = list(float_array)
```

or change the implementation of the fuction compute cost to

```
#Function to calculate the cost
def compute_cost(x, y, w, b):
m = x.shape[0]
cost = 0
for i in range(m):
f_wb = w * x[i] + b
cost = cost + (f_wb - y[i])**2
total_cost = 1 / (2 * m) * cost
total_cost = float(total_cost)
return total_cost
```
