   Hi @toufikoss , 
   As it is a list, it can't be reshaped.
   Convert it into a numpy array and then use it's reshape function.
   i.e. `np.array().reshape()`
   So above feedforward function will look like - 
   ```
   def feedforward(x, W1, W2, b1, b2):
       z1=np.dot(W1, np.array(x).reshape(4,1))+b1
       a1=relu(z1)
       z2=np.dot(W2, a1)+b2
       a2=sigmoid(z2)
       return z1, z2, a1, a2
   ```
   Let us know if it is solved.
